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.

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.
I'm not getting LTE on my Sony Xperia XZ with AT&T. I'm in the U.S but got the UK version from Clove UK because of the lower price and freebies with the preorder. The US and UK Sony Xperia XZ are the same model number and the whitepaper has all of AT&T bands. Both are F8331 meaning there is only one Single SIM version. However the most I get is HPSA (3G?). Calls work fine and voice is very clear and I get full bars, however I can't get LTE anywhere. My friend that is on AT&T and has an iPhone 6S gets LTE with no problem.
I'm thinking that it has to do with the LTE bands being disabled or because it is a UK phone. I understand not getting Wifi-Calling or VoLTE because I didnt get the phone from AT&T but rather unlocked. But I should be able to get LTE, I might be wrong though. Could I possibly get the problem fixed by flashing the phone to a U.S firmware maybe? If anyone could help I would appreciate it.
Got the same phone from Clove on AT&T and LTE is no problem. The issue is most likely IMEI related. I have been using Xperia devices on AT&T for years and this has given me issues in the past. IMEI numbers are recycled and since Sony phones are not carrier issued their IMEI numbers are not loaded in AT&T's database. It most likely is linked to a 2G or 3G device from years past. Give AT&T an IMEI number from an AT&T LTE phone and you will access LTE. Also check APN to see if it's correct.

Yes don't flash the US Firmware, you won't get the fingerprint scanner, I bought the US version of the phone and Flashed the UK version, instead of LTE now shows 4G but is the same just different nomenclature
I can't speak for other countries, but the Singapore firmware reports as LTE on AT&T. But, it doesn't work until you go to Settings -> More -> Internet Settings and let it download.
Then, if you go to Settings -> More -> Mobile Networks, you should see the different AT&T APN's.

A million thanks. Everything you said was spot on. The IMEI as you said was not loaded into the AT&T database since the IMEI for my Xperia XZ is 14 digits vs 15 for an AT&T phone. I asked a friend for his IMEI and went to an AT&T store and did what you told and now I have LTE! Of course it appears as 4G on my Xperia but it's still LTE. Again thanks for your help.

Thanks for your help also. I figured that flashing the US firmware would disable the fingerprint scanner. My phone now shows 4G after I tried the solution to the first reply. Good to know it's the same as LTE. I don't regret buying the phone from the UK bc everything is working out fine.

I tried what you suggested but it still shows 4G. The options are still the same. Apparently it is the same as LTE just shows up as 4G. Thanks though for the idea. It was worth a try.
In the UK LTE bandwidth is marketed as 4g.
You've purchased a UK Sony with UK firmware hence you will see a 4g symbol rather then LTE.

Not sure what you are asking for, but I just followed the instructions from other post don't have the link at the moment, install xperifirm select the uk rom and it creates the ftf file for you, no need to worry about removing the xml file, I even forgot to put the phone on debugging mode it failed at first then I retried and it worked

Thanks! That makes sense. Is there a way to test the speed? And so you are saying 4G is LTE, is that right? My XZ Premium, also from Clove, now says 4G so I should be good to go, right?
Hello I have this phone on EE but as I didnt buy it from EE it doesnt have their EE firmware on it so I cant use wifi calling....
Anyone know a way to add this feature? A work around? Flash the phone? Etc
Thanks

Well, as far as I know there is no hope...
I am in the same situation.
I wanted to have the chrome unlocked version, exclusive to Carphone Warehouse in the UK, so I got mine from CW.
I had many chat with EE and they say that most modern / recent phones support WiFi calling out of the box BUT not the XZP... It has to be purchased "direct" from EE so that it has the firmware that enables WiFi calling...
I asked to Sony support Why they don't include WiFi calling settings in their firmware, as Samsung, Apple, HTC, Huawei, Microsoft,... Do? . They simply replied that this is not their responsibility but the one of the operator... I, don't care!
So, the choice is simple :
XZP unlocked in chrome and no WiFi calling or EEocked black phone with WiFi calling...
I have 28 days return with CW... But will stick with the unlock one. Perhaps in the futur I will flash the EE Firmware, but for now, I don't use WiFi calling enough for that...
With some hope, but unlikely, maybe Sony will include the WiFi setting in their future firmware (if enough people ask for it?)
You dont need to buy direct from EE. It is enough if you just flash the EE version of the image on it https://xpericheck.com/cda/1308-6282
Check around in the forums how the flashing can be done.

Indeed, I could flash an EE firmware, but not sure how to troubleshoot if things go wrong !!! hence I will wait a bit longer for that... (and waiting for the ROM to be widely available.)..
My XZP is from O2. Ive got it unlocked and both O2 and EE wifi calling working. My operator is EE but it was cheaper to buy it from O2.

CW phone is unlocked to all networks so it has different firmware than branded unit. Look around for EE or O2 firmware to get wifi calling enabled.
I've just flashed EE firmware. Wifi Call works even better.

I would like to try this. But my phone is already setup and without root I can't use my trusty Titanium Backup to backup and restore all my apps and settings. A couple of questions I hope you have time to answer:
1. What flash tool did you use to install this? I found the firmware with Xperifirm, but it doesn't look like flashtool-0.9.23.1 is compatible with our phone yet.
2. Did this wipe your phone?
3. Does this firmware come with any EE branding or bloatware?
Thank you for your time.

What are the differences between the EE and Customised UK firmware?
Do you have a EE splash screen when starting and any EE bloatware / limitation?
I am also on a carphone warehouse phone and wondering if I should flash the EE firmware to get the Wifi calling ( I have it enabled on my EE account already and was used to use it in the past on a different phone)...
Thanks.
Tony.
Customized UK loads "telefonica_UK" configuration for any SIM inserted, which means no VoWIFI(wifi calling) or VoLTE. You definately need operator based firmware flashed to get Wifi calling and/or Volte.
No difference at all. My EE app is preloaded I think. That's it.

I can confirm this. The only differences that I noticed was the myEE app. And outlook security instead of avast security. I can't find the wifi calling setting in the EE rom though. My provider is supposed to support it, but I don't see any settings in the rom to enable it.
Edit: I checked with my providers app. It shows that wi-fi calling is not supported on my device. I'll try the O2 firmware to see if that works.
Edit2: Actually, I see the O2 firmware is still on the July security update. Security is more important to me than wi-fi calling. So I guess I'll just keep running the EE firmware.

Are you on EE pay monthly plan? You wont get WiFi Call or VoLTE if you are on Pay As You Go. You should see wifi calling settings if you flashed it correctly on both O2 and EE firmwares.

Hi Rob,
Thank you for taking the time to respond. I'm not on EE or O2. But my provider started to offer wifi calling on some phone models. Even if not purchased from them. For example the Samsung Galaxy S7 has it built in. But they don't support the Sony by default because it doesn't come with wifi calling built-in. So I thought it might show up with the EE or O2 firmware. But it didn't. I just need to go to my providers service point and ask them to force enable it for my phone to see if it works.
ishemes, so what provider you are using then and in which country ?

I'm with the provider Partner (used to be Orange) in Israel. Unfortunately they don't carry the Sony Xperia XZ premium phone. So no official support. The generic Israeli firmware does not have wifi calling in the firmware.
Quick Question
Sorry to jump on a slightly old thread...
I bought a Sony Xperia Z3 Compact for my other half. Brand new from EBay, unlocked, but doesnt have the Wi-fi calling feature, so from what I could find on a forum on EE it seems the Z5 compact has Wi-fi calling (the forum is giving instructions on how to turn it on specifically for teh Z5 and Z5 compact)
Only, reaeding this forum about phones having to be bought from the carrier to use the Wi-fi calling, I am now wondering am I going to be wasting my time buying a refurbed Z5 off Ebay, unless its locked to EE?
Thank you for any help!!
Gemma
P.S. I am the sort of girl capable of flashing, however i'd prefer not to have to do this, because I don't like interfering if I dont really need to

You might get more help by posting in the Z3 Compact or the Z5 Compact forums.
The way it works on the XZP/XZ1/XZ1c is via a set of settings overlays that are in the OEM partition.
Sony puts out different firmware for different carriers and the carrier specific items (like VoWiFI and VoLTE) are contained in the OEM partition contents of that carrier specific firmware.
If the Z5/Z5c work the same way, you should be able to get any E6653 (Z5) or E5823 (Z5c) model phone and download the EE customized firmware with XperiFirm and flash it to the phone. It should be the same as having bought the phone directly from EE with the same features and bloatware.
Again though, I don't have the Z3/5/c series and haven't dug into the firmware images, so you should check in with the people in the forums I've listed above.
Hi there, I recently left EE and kept my Huawei P20 pro phone which they unlocked for me, I joined O2 on a sim only contract, but stupidly never thought to check if the wifi calling would still work for this phone on O2. I've contacted O2 to try activate WiFi calling on my account and I can see its been added to my account, but can't see the option on my phone settings. I have been reading many sites and posts that it won't work unless my phone has the correct O2 firmware on it. Can someone confirm if this is true and if so, does anyone have the correct firmware for this and how to install it too, as I am really missing wifi calling and texts while I am away at work offshore with no phone signal!! It's a P20 pro CLT-L09. Thanks for any help you can give me, kind regards, Andy
I don't think WiFi Calling will work on P20 Pro on O2. When I've been using it, it had no option to turn the WiFi Calling on. In Huawei, it always depends on the generic software version (basically, there is no branding). But, if O2 haven't certified this option, it won't be available. Is P20 Pro on the O2 list of capable devices?
Yeah it's on the list on the website, it seems to be a common question to O2 but no one get a good reply with a solution. I'll attach a screen shot of the ifo on their website. I think my issue was that my phone was locked to EE and WiFi calling worked with the EE simcard in, but its now unlocked with an O2 sim card in it and no wifi calling available, so really hoping someone has the O2 firmware available that I can install onto the phone fingers crossed to save having to buy a new phone from O2.

If it won't work, I would try Factory Reset the phone and then install all the updates. There should be an update from O2 available (network settings or something like that).

Did you manage to solve this:? I have the same problem....
Hello, there is a common USA Issue. pretty much every phone which is not sold through the provider lite ATT / Tmobile etc all the Phone features like VolLTE and WIFI Calling are not possible and locked.
A sim Card in one of their phones works. Using any of the XIAMOI i.e. or phones all the features work with any provider other than the US ones. Is this something where they

Because the US devices are carrier/SIM locked unless the device is unlocked using the device's/carrier's specific unlock method. As far as I know, Volte and Wi-Fi calling are setup and regulated by the carrier from their end, not on the user end.
Well I think we missunderstood a little SOme us Devices especially ATT are "SIM" Locked this is a total different avenue .
I am talking about WIFI Calling. Szenario :
I have a us SIm Card WIFI Calling VoLTE in US Phones Iphone and the few Androids (99% Samsung) they sell working fine
I use a European Phone works fine with almsot any provider (WIFI Calling and VoLTE) in most phones from euopr and the US phones as described above.
Use Teh US Sim Card in one of the EUropean phnes every thing works in terms of Data and VOice,Text but "NO" WIFI Calling od VoLTE . WIFI Calling is not even showing up.
My question is as simple as it can be "WHERE" and what technology swith the features on and OFF ? It must be recognized by the IMIE Number or IM Wrong ?
