[Q] Help with Dual SIM in UK region - Xperia Z3 Q&A, Help & Troubleshooting

​Hello everyone.
So i thought i'd be really smart and pick up a new Xperia Z3 from a foreign website (based in Dubai) as it had the Dual SIM model on offer... Only trouble is this phone seems very 'fussy' with which SIM cards i put in it back in the United Kingdom.
EE - SIMs are rejected outright with a nasty message that doesn't go away til i take it out
3 - SIM is simply not acknowledged at all
O2 - works
Vodafone - Works but gives me no LTE (only 3G and HSDPA)
I would really like to use the phone with either EE or 3 since they offer the best reception / network speed / costs in my area. Any suggestions for me? Should i use a different ROM?
Many thanks!!
Charlie
PS Amazing Battery life on this thing by the way - very happy with it otherwise. Just kinda miss having 4G / fast LTE

Hello Charlie,
Did you get this sorted? I read somewhere that a software update fixed the EE card rejection issue?
I'm looking at getting this phone myself as I use EE but no signal in my work building so I miss calls. However I know O2 works so I was going to get a PAYG O2 SIM and have EE forward to O2 when at work so I can receive calls.
Cheers - Mark

Buying Touch Pro in Japan?

Hey all,
This is my first post here; just found the website. I've been looking for something like this!
Anyway, the reason for my post is that my current freebie cellphone dropped from a high perch last night and shattered into a hundred pieces, finally giving me an excuse to pull the trigger on something nicer. I really like Docomo's Touch Pro, but I'm hoping somebody here might answer two questions about it before I drop 50,000 yen.
1.) The menus are all in Japanese and I've been told they cannot be changed to English. My Japanese is decent but I'm sure for such a sophisticated piece of tech, I'd like everything to be in English to take advantage of fine tuning, etc. Would there be a way to reformat the phone to put an English version of Windows Mobile on there, and if I did, could I still input Japanese characters?
2.) I'm going to be in Japan for at least another year and a half or so, but past that there's a chance I might have to go back to the US for work. If I did, what are the odds that the Touch Pro would work on a carrier like AT&T or Verizon? Are the 3G frequencies too different?
Thanks to anyone who replies

Don't see why you could't change the language by flashing a new rom on, and if you need to enter japanese characters there are software keyboards that let you input them from memory.
1) You can install a WWE rom just fine, there are XDA members who have done this already. Then use the Japanese display/input cab found here to re-add Japanese support. You may need to do additional tweaking for specific apps or to get the keyboard right, but it shouldn't be very difficult.
2) The HT-01A will be locked to DoCoMo, but you can get it unlocked (a quick search on XDA will point you in the right direction) which will allow you to use it with an AT&T SIM card. Important note: DoCoMo uses UMTS 2100 for 3G while AT&T uses UMTS 850/1900, so you will need to make sure the HT-01A supports the latter if you want to use 3G with AT&T. The same goes for SoftBank X05HT. Otherwise you will still be able to use regular GSM/EDGE.
Verizon uses a CDMA network so it will not support either HT-01A or X05HT. au/KDDI (which also runs on CDMA) also has a Touch Pro, the E30HT, however it is next to impossible to switch networks with CDMA devices.
Your other option is to buy an unlocked AT&T Fuze/Touch Pro from the US (eBay?), which supports UMTS 850/1900/2100, and bring it to Japan to use with DoCoMo or SoftBank.
Of course, depending on your situation, you may have an easier time getting a Touch Pro from SoftBank than from DoCoMo due to their contract requirements.
anyone figured out how to get sms working in japan? my friend with his 8525 in tokyo can't sms my fuze in seattle.
Wow, I hadn't even considered importing a Touch Pro from the States. If the AT&T version supports both US and (Docomo) Japanese 3G frequencies, that sounds like a train I need to get on. Any idea if the folks at Docomo will have a fit if I bring in a foreign phone, or will they set me up no questions asked?
I did a quick search and found this (hopefully it's ok to link to ebay here): http://cgi.ebay.com/New-Unlocked-AT-T-HTC-Fuze-Diamond-Touch-Pro-P4600_W0QQitemZ160302176188QQcmdZViewItemQQptZCell_Phones?hash=item160302176188&_trksid=p3286.c0.m14&_trkparms=72%3A1205|66%3A2|65%3A12|39%3A1|240%3A1308|301%3A1|293%3A1|294%3A50

get setup on the cheapest POS phone you can get from docomo, then transfer your sim to a sim unlocked touch pro. my friend uses his unlocked tytn II in japan without problems.

It will depend on his carrier (DoCoMo or SoftBank) and what plan he's using, whether it will support forwarding SMS internationally. Most people in Japan use the hybrid MMS/email services (which are pay per-byte rather than per-message). With it, messages are sent as regular emails (but "pushed" to the phone using MMS delivery); which means you don't have to worry about international routing, just send emails to each other as you normally would.
For SoftBank subscribers, you will need MMSLite (3rd party) or S!Mail (SoftBank). MMSLite is rather limited in functionality, and S!Mail is a little slow (although I hear newer versions are much faster). I don't know specifics for DoCoMo subscribers, but I imagine it's a similar situation.
Of course your friend will probably be able to get more help by going into a store and talking with a representative.

Yes, as bani1 suggested, you should be able to just buy a cheap phone from DoCoMo (UMTS 2100 network) and transfer the SIM over to a Touch Pro/Fuze (UMTS 850/1900/2100 support). The Touch Pro also includes automatic network configuration profiles for both DoCoMo and SoftBank. For DoCoMo, you will need to subscribe to their "FOMA" service. For SoftBank, you will need their "3G" service. You will not be able to subscribe to eMobile (UMTS 1700 network), au/KDDI (CDMA network), or Willcom (PHS network).
Again, depending on your living situation (non-permanent residency documentation), you may have difficulty getting a phone from DoCoMo, so keep in mind that SoftBank is the other option in case you're unable to subscribe with DoCoMo.

The last time I was in the Docomo shop, they told me I had to get some business-class data plan to go with the Touch Pro. Should I request that with the freebie phone or can they even differentiate if I get a regular data plan and use it with a different phone? Kind of curious what steps your friend took when he signed up.
Thanks guys, I really appreciate your help. Importing an AT&T version from ebay would seem to bypass a lot of the headaches of reflashing the rom, and I have a foreigner registration card so making a contract with Docomo shouldn't pose any problems. This is exciting! I left the store so disappointed last week when they told me it the menus couldn't be switched to English.
Yo!
1. NTT docomo's touch pro is like all of ours and can change the language within your phones settings.
2. NTT docomo can roam on US's GSM network and whether it will take a US sim card you'd have to ask the sales rep(hopefully he knows what a sim card is, doubtful).
Japan and Korea are the 2 only countries in the world that can't be roamed to. They use a different system called W-CDMA, but do have GSM bandwidths in the phone itself and can and DO roam in the states. I have seen some NTT phones with SIM card slots that are being used here.(US) You might want to also check out Softbanks model and see who's Data charges are lower. Japan is notorious for Data charges. Both NTT and Softbank are the same network and phones are identicall (touch pro that is).
Anyways, thats my 2 cents.

Actually, I looked through the X04HT rom and it's missing most (if not all) of the 0409 (English) MUI files. Almost all of the apps include only 0411 (Japanese) MUI files. I'm sure it's the same with X05HT, as well as DoCoMo versions. You may be able to change localization to US (which will change the names of days/months and various units to English), but most of the text menus will remain in Japanese.
W-CDMA is the baseband, UMTS is the network system. In the US, AT&T also runs a W-CDMA/UMTS network. But DoCoMo and SoftBank run W-CDMA/UMTS 2100mhz, whereas AT&T runs W-CDMA/UMTS 850/1900 (in addition to GSM 850/1900).
These days you can bring any unlocked UMTS 2100-capable phone to roam in Japan. SoftBank even lets you rent SIM cards at ¥500/day if you're just making a short visit. But you are still right that you need to pay careful attention to your data usage, at least for the first month or any month thereafter if you make changes to your service, so that you don't unwittingly end up with a ¥50,000+ bill.
hey there! Wow, do you live in Japan? One thing ,how would I roam with a sim card from softbank? When I say roam I mean roam with my phone and my phone number. Also w-cdma is the regular radio network. UTMS is the 3G bandwidth. And I thought AT&T was GSM?

AT&T runs both W-CDMA (UMTS 850/1900) and GSM (850/1900) networks. Of course their GSM network has wider coverage. Any phone that does not have UMTS 850/1900 will fall back to regular GSM.
SoftBank SIM rentals are not intended for roaming. If you rent a SoftBank SIM, you will receive a Japanese phone number, and all calls and data connections will be made locally through SoftBank (as per their rental SIM rate plan). You can still make international calls but they will be charged at SoftBank's rates.
If you want to keep your original phone number, you do not need to rent a SIM card. Just keep your original SIM card in your phone. For example, if you have an AT&T SIM (and therefore a US phone number), your AT&T SIM will roam while in Japan. AT&T has roaming agreements with both SoftBank and DoCoMo, so your phone will simply connect to whichever network has greater coverage in the area you travel. You will be subject to AT&T's roaming charges, as detailed here:
http://www.wireless.att.com/travelguide/coverage/coverage_details.jsp?CIDL=392&MNC=CING
Of course, the only way to be able to roam in Japan is with a phone that supports UMTS 2100. As mentioned earlier, it is not possible to connect to eMobile (UMTS 1700), au/KDDI (CDMA), or Willcom (PHS) networks.
SoftBank X05HT
hi there! another newbie here. i'm living in japan and yesterday i purchased my SoftBank X05HT but wasn't told english was not available on it! being such a hi-tech piece of kit i really need to get english on it. i've been follow the advice given to Jonathan24 but being a novice i'm a bit concern that i will muck it up in some way. i understand that the japanese phone network is slightly different to european/american networks and am worried about installing a WWE rom. will my phone's services still fully function on the softbank network, S! Mail, 3g internet, etc?
Hi,
I moved from Germany to Japan 2 month ago, and brough my European Touch Pro (sim free version from HTC, not one of the T-Mobile sim locked ones).
I have a WWE rom flashed and run it on Softbanks network without problems.
My rom does not have S!Mail, but so far, I do not miss it.
One thing I have learned in Japan is, that people in tech stores like Bic Camera, or in mobile stores like Softbank or DoCoMo normally have no clue what they are talking about.
Whatever you ask, that is a little more than their standard, the answer you will get is: "That is not possible." 10min on google or here in the forum, and you will find a solution.
One thing that I am interested in is the radio rom which comes with Softbanks Touch Pro.
If anybody has it, please share.
Thanks.

This is correct.
You can change Tocuh-Flo to English relatively easily - there is a patch on this site, cant remember where, but search will find.
I have a DoCoMo HT-01A (X05HT, Touch Pro). I dumped the orginial JP ROM to raw files, (haven't cooked it yet) and flashed using ROMeOS2_140_1_ENG_19974_15112008 with Raphael HardSPL first and then booting the ROM from the SD card. Flashing was a piece of cake.
I haven't extracted NaviTime, the GPS app, cause I downloaded Garmin and Japanese maps from a certain swash buckling place

In the X04HT ROM, NaviTime is included simply as a CAB installer (rather than OEM package). But I tested it and was not particularly impressed. Garmin has better routing, and PocketMapple has more detailed maps.
Oh, and Diamond TF3d Config will take care of the TouchFlo language setting (among all sorts of other tweaks) -- no need to search for the MUI patch.

Flashing a ROM does not change your phone's radio, so it will still be able to connect to SoftBank (calling, 3G internet, etc) just fine. You will be able to find more information on flashing a WWE ROM in the Touch Pro ROM section, but just to confirm, you will need to install HardSPL through ActiveSync, then choose a ROM and place the .nbh file on your microSD card, and follow the steps for hardresetting/loading new ROM.
Of course you will probably lose any 3rd party apps that come pre-installed with your phone, so you may need to use the Application CD that came with your X05HT to reinstall them. As for S!Mail, you should be able to download the CAB and reinstall it by accessing your My SoftBank page from your phone using Internet Explorer. Here are the instructions for the X01HT, but it should be similar for the X05HT. I recommend getting the S!Mail CAB and any other necessary files first before flashing a new ROM (or at least performing a full backup).
You should also make a note of the connection settings so that you can make sure they are correct once you flash a new ROM. In the past, SoftBank has used different connection settings for different rate plans (I don't know if it's still the case), and some people have used the wrong settings after flashing their ROMs only to be faced with a huge bill at the end of the month. So this is another fair warning to be mindful of your data usage for the first month (or any subsequent month after you make major changes to your phone) -- unless of course you are confident you're using the correct settings.
So I went ahead and ordered an unlocked AT&T Fuze off of Ebay last night and it's on its way to my family's house where they'll repackage and send it off to me. I thought I should confirm something while I still have the chance, however.
I'm a resident in Japan so rather than roaming, I'd like to be able to use this with a regular Docomo subscription plan. If I get that crappy starter phone and then switch the SIM out to the Fuze, will it work the same (same phone number/email address, etc) with a regular subscription instead of trying to roam? Are there steps I need take to ensure that it uses the radio/data plan in the same way, or is all of the information contained in the SIM?
Also, what would technically happen if I walked into the Docomo shop the day I made my contract and said "Hey, I already have this nice smart phone, can I just use this?"
Thanks again, especially to fhsieh! You're a lifesaver!

The phone number will automatically be transferred to whichever device has the SIM. The basic network settings are contained within the SIM, and the Fuze contains an app (Start > Settings > Connections > Connection Wizard) that will automatically set up any additional connection settings for DoCoMo (the app is also part of most other TouchPro ROMs, in case you want to flash a different ROM). A DoCoMo SIM inside Japan will not roam.
You will have to enter email settings manually, but I have no experience with DoCoMo so I don't know if they use a specific app (like SoftBank does with S!Mail), or if you can simply enter it as a standard POP/IMAP account through WM6.1's default messaging app. Of course, with data access, you can simply tell your contacts to use your own email (and not a docomo email) for messaging -- you should not incur any additional charges for that.
For your reference, here is the full manual for the HT-01A:
http://www.nttdocomo.co.jp/support/trouble/manual/download/pro/ht01a/index.html
One note: you may want to take a look at section 14: "データ通信/ワイヤレスLAN" (pages 171-186). It contains connection settings for DoCoMo's "mopera U" data plan. You may need to set it up accordingly if you subscribe to that rate plan. And on that note, I would suggest taking a look at which plans are intended for use with the HT-01A, and then choosing the cheapest phone that uses the same plan(s). You wouldn't want to just buy the "most basic plan" and be caught off guard with high data charges if the plan isn't intended for use with a data-heavy device.
If you feel adventurous, you might also buy one of the models that can be hypersim-unlocked (for use overseas) and sell it on eBay.
And a last thought: if you have multiple DoCoMo stores in your area, you may want to "test the waters". Some stores/clerks might give you the cold shoulder while others might be very helpful. Although IMO, saying "I already have this phone, can I just use it?" won't do much because either way they're not required to support non-DoCoMo phones (the worst that would happen is they might refuse to open an account thinking you're trying to circumvent their plans; at which point you could just go to another DoCoMo store). But you shouldn't need any extra help -- your cheap phone should have all the necessary connection settings, and it's just a matter of copying them over to the TouchPro.
DoCoMo Bizhodai Data Plan
The data network plan I was told I have to use with the DoCoMo HT-01A phone is called Bizuhodai. (Mopera U is their email plan.) I bought the phone and flashed an English ROM on it and now I can't get the phone to connect to the data network.
Any DoCoMo users able to flash an English rom and get it to work with the Bizuhodai data plan?
Thanks,

[Q] UK phone wont work in US

i have a htc desire Z currently and i recently went to california to spend some time with my gf's family but my phone just did not work over in america....
im in a 18 month contract with Orange (or EE now) and when I got to america i was not registered to any UK carrier so I tried to connect to the two possible carriers available T-mobile and AT&T but both said my sim card was unable to register with these carriers.
i have no idea why or what causes this issue but i want to make sure that next time when i leave to go to the US my phone is going to work...
im getting a new phone soon and want to know what the fix is before i get a phone that wont work in the US again...
PS. im rooted and using a custom rom called mimicry if that has any foot on the problem.
thanks in advance
Are you still using the SIM card from the UK? If so, you need a US SIM card to communicate with the GSM towers here.

i brought my gf a phone a Tesco mobile carrier in the uk and hers worked over there... so some work, i just need to know which ones do or how i can connect to the gsm towers. i dont actually care about using the phone service too much because i mostly do my networking via skype and whatsapp but i was unable to access the wireless connection too (probably related as well)
no access to any signal was available. my gf had no troubles though, she texted and called and used internet on wifi but internet didnt work outside of wifizone which is the same thing im looking for.
bump - does anyone have any information on this?
I hear sth about it usa doesnt use umts and they have different frequency than Europe probably this is the reason

Before you buy your new phone, check on GSMArena for the full specs and see what frequencies it supports - then make sure those match with the frequency your planned provider in the US uses.
And, please don't 'bump' your own posts - there's no need and it's contrary to the rules of XDA to do so within 24 hours.

is there a possibility to change the radio part of a rom in order to use frequency to at least get onto a network?
my phone
gf's phone
it appears as though my phone has the ability to work in the US however it appears to work with either one or the other and not both at the same time... if i got that correct?
(seeing as USA coverage accepts UMTS 850, 1900, 1700 and 2100 and the UK uses UMTS 900 and 2100 i need to look for a phone that runs on 2100)

Z3 Dual D6633 SIM compatibility / issues

Hi, I've got a Z3 dual D6633 which I want to use with an EE SIM in the UK. I've tried a cut down microsim and been into the EE shop and tried one of their nano SIMs but both don't work correctly in the phone.
The cut down SIM makes a service phone.android.com or something like that continually crash and doesn't connect to the network.
The one I tried in the shop just doesn't connect to the network.
This is on 23.0.F.1.74 and .82 I noticed in the release notes for .82a fix for Yoga SIMs in Russia but don't know what the problem there was, but wonder if it is linked. All other UK Sims work including 3, Lyca, giffgaff, Vodafone, virgin just not EE. has anyone got an EE one working or had similar problems?
I did notice that an app/widget I use called phono to show network info and signal strength usually shows the IMEI when no SIM inserted or the MSISDN, however with the non-working EE SIM it just shows 00000 - not sure which field it is getting wrong. Oh and yes the SIMs work fine in all other phones I've tried.
I do need to try more tests on factory reset and removing phono etc but so far it looks to be a firmware incompatibility with EE Sims.
OK, so I did a few more tests and got hold of another nano SIM on EE.
So it looks like the 23.0.F.1.74 firmware does not like EE SIMs and the phone application constantly crashes. On the later .82 firmware it works fine. I was mislead a bit by going into an EE store and trying a SIM - they must have given me an un-provisioned SIM to try. I stupidly assumed they would have actually given me a SIM that worked, doh!
I'm experiencing something similar here. I have the D6633, bought in UK, now I am in Brazil and the phone works great except that it won't connect to the 4G/3G/2G/LTE network. I can make calls, send sms normal. But internet only over wi-fi.
I called my operator, they say the phone is configured correctly, I tried my brother's sim card from another operator and the same happens.
So, the phone is clearly unlocked, if not it wouldn't recognize the sim cards at all. But no connection to the internet...
Any suggestions? I already did four factory resets, I recovered the Rom using sony software...
Same issue

Hello, I have the exact same problem. How did you get the firmware .82/for what country? Is everything working well with it? Really appreciate your guidance.
I had the same problem with the EE sim card, ended up sending the phone back.

Just a thought, but is it definitely a 6633 and not some other variant which perhaps doesn't work in your country/network?

I purchased my D6633 from Saudi Arabia and the 23.0.F.1.82 update came as an OTA notification about a week ago.
If you look in this thread http://forum.xda-developers.com/z3/general/d6633-z3-dual-updated-to-23-0-f-1-82-t2929352/ it mentions that someone thinks the update has only been released for Saudi and Brazil - I assume it is for Europe as well as one of the release notes says a problem with Russian Yota SIMs has been fixed. I think there are also links to the firmware in there although I've not looked that hard as I got the OTA. I guess it might still in my memory - anyone know where Sony stick their OTAs?
Seems to work fine so far - no noticeable difference - well other than EE SIMs now work!

Ah, shame as it looks like the update might have fixed it. I was thinking I might have to go to another handset too (The Samsung G900FD is OK if you can put up with touchwiz and other Samsung "features"!!)

Hmmm, sounds like another issue as with mine the EE SIM caused the phone.apk to constantly crash/restart.
Did the data work OK in the UK?
As you can make calls/SMS I assume you are at least on a 2G network which should still give you (very slooow) data - It does sound more like an APN issue - or something else. I know you said you checked with your operator what their APN settings should be (just my experience with operator customer support lines) - but I would try and have a look yourself - and maybe list your APN settings and operator and someone may spot something.
I have seen a couple of phones / operators where the "APN type" in the APN settings needs specific settings - its down the bottom and often isn't mentioned when people get the settings. For example in my current settings I have "default,hipri,dun,supl" for Virgin mobile in the UK.

It was working fine there. Here It apparently could not download APN settings, so I installed an APN APP and now it works fine!!!

I see. Mine is the d6633 but it is customized for HK. I have not received the OTA upgrade yet. I have checked xperifirm as they may have it but will wait for the OTA upgrade. Sony must be releasing soon.
Thank you for replying! I am using Vodafone in the meantime, but want to go back to my EE plan!
about dual sim connectivity
can anyone tell me which sim card slot support 2G, 3G and 4G or LTE
I heard that 1 slot support only 3G and 4G
and other one is support 2G & 3G so kindly confirm me what is actual.
thanks

For mine, on my networks here in Australia, I can assign 4G LTE to any sim, however, that makes the other sim 2G only (GSM).
The other option is to have both at 3G (WCDMA/HSPA).
If you assign 4g to sim one that work only for 4g or like other phones "LTE(preference)/WCDMA/GSM"
4g not available automatically search 3G if 3G not available automatically search 2G?
Assume second sim is on 2g

Yes, your 4G sim slot will fall back onto 3G and 2G as per expected for most handsets.

I just got a 6633 through kogan and i am having real trouble getting it to connect to optus network with iinet and truphone simcards. Does anyone know if i need to update any settings or firmware from factory to make it compatible. I can see iinet and truphone lte networks (which i assume is the optus 4g network) when searching manually but the phone wont connect. Sims work in a mates iphone6 without a problem.
Don't suppose anyone knows how to get rid of the #sim card icon on the statusbar?

Have you managed to root it? I rooted the 23.0.1.f.0.96 firmware for my Z3 D6633, but after a while (half a day) it starts to reboot frequently, and Google Play stops working (can browse apps, but not download them, as the download bar never progresses).
Also, my EE sim seems to work, but the phone still shows it as 'Sim 1 0000000' whereas other sims simply appear as sim 1 and sim 2.
I am wondering if I should just downgrade back to 23.0.F.1.74 and move from EE to Vodafone or 3...
Ah, work forced a BlackBerry (yuck!) on me and I've since sold the D6633.

Dual Sim

Has anyone used this feature? It was one of the reasons I got the phone - I'm planning on moving my landline number to the phone. AT&T said they don't support dual sims (if it works it works, if it doesn't - sorry!). So I thought I'd ask to see if anyone is using dual sims (preferably with AT&T) and how the experience is going .. thanks!

I have two sims in it since day one - works great!
I made this little video of how Dual Sim cards works on this phone:
You can switch data source without taking sims out (in settings)
2 AT&T sims will work just fine - it does not matter who the carrier iss as long as phone can read the sim cards. I use two t-mobile sims. People here have both t-mo and AT&T sims in.
Can't help you when it comes to AT&T as I'm in Australia these days, but we've had mixed results. My wife has a Blu Pure XL and I use a OnePlus 2. Both of us have SIMs on Virgin (Optus reseller) and Telstra - mine are prepaid, hers are postpaid.
In her case, having both SIMs activated leaves her primary Virgin SIM nearly useless. She can surf the web but no other apps work over broadband (including Email, Hangouts, Location services). If she takes it to a Virgin store and finds a sympathetic employee, he/she can go and "reset the back end" of her account and everything starts working again - for about a day or so. Other employees simply check the settings and proclaim it's a software problem with her OS.
In my case, everything works normally - except when I'm at home. When at home I need to disable the Telstra SIM (data-only) on my OP2 in order for the Virgin SIM to work in any capacity. I've checked and my local tower supports 2G, FWIW.
Of course, Australia and the U.S. are not known for dual-SIM phones - they're more popular in countries where you can't rely on having coverage from any one company as you move about. It's arguable that dual SIM phones potentially cut into the market of any individual mobile provider, so I doubt you'll find anyone willing to support them.
I doubt any provider will actively block the feature, but if some quirk of their setup causes you a problem, you're probably on your own.
For what it's worth, I've seen both the OnePlus 2 and the Blu Pure XL use dual SIMs perfectly well. Just - not all the time!

eSIM/dual SIM on AT&T variant

Got my AT&T variant today. Doesn't look like eSIM funcationality is enabled. Second IMEI and eSIM shown but greyed out and no way to activate. Is this true? If so, does anyone know if unlocked version allows for eSIM use so you can get dual sim? I need dual SIM for both US (AT&T) and international travel (Singapore).
no dual sim on unlocked version either

Really? Why put the eSIM in if you're just going to disable it?
well that's a bummer. Hopefully someone will come up with some firmware or we'll see a country release the 4G version of the phone that will work in the US and support dual SIM. I do, however, use wifi calling a lot and right now the iPhone seems to be the only choice that can be AT&T wifi calling compatible and dual sim.
Thanks for letting me know - i also had an order for the unlocked variant that I will cancel.

Pixel 4/4XL unlocked versions (as well as bought thru AT&T) will do Wi-Fi calling and HD Voice on AT&T (sometimes requires a little work on your part to bug AT&T).
Also, I cannot find anyway to do Wi-Fi calling on the Flip, let alone HD Voice, though it is perfectly clear with calls I have made so far.
I bought the ATT version of the flip so getting wifi calling. I didn’t think Pixel 4 was dual sim? Before various bans, I had decent luck getting HD voice on Huwawei phones but never WiFi calling unless ATT firmware (or iPhone)

Typical AT&T treatment of BYOD with regards to Wi-Fi.
Pixel 4's are physical SIM and eSIM.
Basically you can (if you find a tech who can/will) provision the account with an IMEI that supports those features, and your SIM is current, it will/should work. My 4XL is currently set up like this (and previous Pixels as well).
Thx didn’t know about the pixel 4 - I did the same thing with IMEI numbers. I bought a cheap galaxy phone from ATT for the sole purpose of having an IMEI that shows ATT. It won’t help WiFi calling which needs firmware support but has consistently gotten HD voice to work. Hopefully a different variant of the flip will show up with dual sim support that can be used on the ATT network

Slightly off topic, but if you have a minute, could you post where the setting(s) for Wi-Fi calling actually are (if there is any), I'm curious to see if they are on mine (I can't find any as of yet).
Thanks.
It gave me the option to setup when I ran. Y hone setup. It’s all under connections in setting or you can search setting for WiFi calling. I believe this is only available with the ATT firmware

I just wanted to make sure I wasn't missing something obvious, and yes, seems its only on AT&T branded device(s).
On the unlocked version, I was able to access the hidden SIM manager menu using Activity Launcher and enable the second SIM. However, even after doing so, it doesn't seem that I can do much with it.
I saw same you can see it but it's not really enabling it (under about phone, esim is still greyed out). I bought a European Version of the phone that is supposed to have dual sim enabled and is arriving tomorrow - I will report back if I can add my AT&T plan to the eSIM and use my SG SIM card on the second line and how it works. Even if I get that to work, i will have to give up wifi calling (since not an AT&T variant of the phone) and usually - Samsung pay doesn't work (but usually google pay does). i will report back. Love the phone but without the ability to use 2 SIMs, it will sadly be doing back.

I thought that the Wi-Fi calling piece was becoming more universally supported, regardless of variant. I have the unlocked version and Verizon Wi-Fi calling (and HD calling) are both working.
Hi, I got one in Czech Republic and the dual sim (eSim/normal Sim) dual standby. the setting for eSIM are under Connections>>Sim card Manager, there should be a section with eSIMS and you select 'add mobile plan' (in CZ you scan the barcode of the eSIM thats provided by the operator). Wifi calling is in the phone app under call settings and can be activated for both sim 1 and sim 2 at the same time
I got the UK version of the phone. I have an AT&T phone number on an eSIM and have the eSIM card (with the QR code). I removed the plan from my old device (a Galaxy Fold Dual SIM I bought in Singapore that worked fine with both SIMS) and then tried to "add the plan" onto my new flip. I scanned the QR code and get the message "Your mobile plan is already being used on another device. For more information, contact your service provider.: I called AT&T and advanced tech support added the new IMEI's(both physical and eSIM) to that number on their end but still getting the error. They were at a loss for a solution. Any ideas on how to fix this? Really love the phone though useless to me without the ability to use an eSIM for my AT&T number.
BTW, yes to calls over LTE (VoLTE) with AT&T SIM on UK variant of the phone and, not surprisingly, no joy on Wifi Calling
You need a new QR code from ATT. If you are using an older QR code it wont work.
Are both SIMs 3G capable?

I gonna buy the UK model and so I can use both my personal and company numbers on one phone.
My company's number is nano sim and the supports 3G and 4G
My personal number is esim and supports 3G and 4G
Neither my personal nor company number network support 2G.
I read somewhere that while Z Flip is dual sim, one of the sims only support 2G. is that right? Can anyone confirm it?
went to AT&T store, moved my old esim (galaxy fold) to a physical sim, activated and tested on physical SIM then converted it again to eSIM (new QR code). Worked! Had trouble going from eSIM to eSIM but converting to physical SIM in the middle of the process (something I read on another forum) fixed it.
