I have just upgraded my O2 XDA Mini S to an O2 XDA Orbit. I'm trying to pass the wizard on to my son who currently is in a monthly contract with the UK 3 network. Both the Wizard and Orbit will not recognise the 3 sim. I've searched widely and find a lot of conflicting opinion but some say that the 3g card will work on a 2g phone (albeit talk and text only without the 3g frills). Does anyone have any advice. The wizard is unlocked and accepts O2 and Voda cards. Is it the O2 software that needs replacing or is it that the card will never work on this particular unit.
Thanks
Three Network now has both GSM and 3G coverage for a full UK coverage. As such, it *sometimes* works on non-3G phone. Depending on your area, I think. But, in general non3G phone (i.e. the Wizard) doesnt work well with Three

Thanks for the rapid reply. Yes, the fact that 3 backs up on to Orange to give full coverage set me wondering. The phone will not even accept the sim - saying no sim or invalid sim. Is there some kind of barring actually operating on the sim to prevent it's recognition by any phone other than a 3 supplied unit? Odd one this.
Well, the common one is SIM-LOCK phone, that the case where the phone is locked to a specific SIM only. i.e. A-SIM in A-Phone, B-SIM doens't work in A-Phone.
However, it is unlikely that you have a Phone-lock SIM, or rather, barred IMEI. That is, the network only works on phone (i.e. with the IMEI) that is registered with the network. Hence, A-SIM will not work on B-Phone because B-Phone's IMEI is not registered with A-Network. Technically, you can do that, but I can't seems to see what's the business benifit of it. Further, you may check this buy going to their website and see if they are selling SIM only package. If so, they are unlikely to be blocking unregistered IMEI, more likely they (the phones) are not compatible with three network.
If you were to go to the Universal forum, there are people using Universal (a 3G phone) with Three Network. I'm not sure if these phones are from them, but my hunch is they are not.
Thanks for the info

I have this problem on mine too i wan to use a 3 sim in mine, mine is unlocked to all networks but three sims dont work, believe three sims are a different type of sim and thus dont work in phones not designed to take that type of sim, as my bro has a newer pocket pc phone and m sim works ok in that, think iv read somewhere they use different voltages or frequecy or something?!?
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

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?

i am currently traveling around and i have bought the sim unlock code for the Infuse and it works great. i can use the sim cards from Taiwan and South Africa without a problem.
But the 3G capability on the sim cards are not working on the Infuse. i tried with my other phone i bought unlocked GS2 (international version) and the 3G was working great
do i need to root in order for the Infuse to be able to connect to 3G with other country's sim card? or i just need to do some setting on the phone?
please help, it's annoying carrying this big phone and unable to use it properly
thanks
You will probably need to put in the correct APN settings for your carrier. Many of the other ROMs will update the APN automatically, but the stock
ROM does not.

As PVD04 said thats an APN problem, go into google and search for the company you like for example i use 3g here in mexico and i typed " Telcel APN configuration" (Telcel is my carrier)
Do the same for your carrier on the country you currently are, then go into--->Settings--->Wireless and network--->Mobile Networks--->APN (access Point Names) and configure a new one typing the data you found about your overboard carrier.
That will fix it.
Also... i know its already done but... you dont need to buy the unlock code" many samsung phones can be unlocked for free Infuse can, searchf or the "how to unlock" thread next time =)

I wonder if this is what happens? No Mobile Data connection.
same for EU phones - if you bought from EU you'd have to 'unlock' it first with an EU sim else it won't work

He switched my S8+ from Tracfone to T-Mobile with all bands working w/ 4G LTE to the point one can't even tell this phone belonged to a different carrier than T-Mobile.
P.S. I had the same issue to where I could connect & surf the Internet with 4G but I was unable to make calls/texts. After he did his magic, which was remotely by the way, my phone got a new life. I bought his service four days ago and my phone is working phenomenally well so far. Give it a try guys.
Does anyone know of a way to unlock the T-Mobile bands on this phone? - the SM-G955N, Can it be done?
There are no clickable options when I access the service menu.

There are no clickable options when I access the service menu.

Thank you for the recommendation, I'm glad I tried this.
Unfortunately, they DoctorSim was unable to help me as my phone is on the t-moblie network but is not prompting an unlock code.
When I enter this code
*#2683662#
ServiceMode
Not supported
Mobile: null
Mobile_IMS: null

No problem. Hmm maybe you will have to do it through T Mobile? I recall that Doctorsim took a long time to work, but it was guaranteed for the phone to be unlocked. Also, did you purchase the premium?

On second thought maybe it cannot be done. I pulled this from a previous XDA thread. Source: https://forum.xda-developers.com/galaxy-s8+/help/ive-korean-model-s8-questions-t3590720
"*Since September 2013, Samsung has implemented a 'region lock' on all new stock.
For correct operation, this handset should be activated inside one of these countries with a SIM card issued for use there. The device will then be able to accept SIM cards from outside of these countries.
Activation requires turning the device on for the first time & completing set-up with the SIM installed, then completing at least 5 minutes of voice call(s) with this SIM.
Without activation you may still use the device outside of these countries when 'roaming' - using a SIM card from the listed countries.
If this activation procedure is not followed then the device will lock when first attempted to be used with a SIM card from outside of these regions. Local Samsung support may provide a code to unlock such handsets.
**All member states of the E.E.A and the following additional territories: Albania, Andorra, Bosnia and Herzegovina, Former Yugoslav Republic of Macedonia (F.Y.R.O.M), Monaco, Montenegro, San Marino, Serbia and Vatican City.
From what i understand you might need a sim from Korea to activate it once activated it will work worldwide with any sim card. i could be wrong but that’s how i think it works!"
Another user stated that "Confirmed I had to have my SM-955N unlocked and used in Korea before shipping. Also have the KT logo. Back is actually less busy than other versions without all the FCC, CE etc logos."
Thanks for the help with this!
I am considering mailing the phone to Korea to have someone there do the sim card activation.
But before I do this I want to make sure I understand the lock issue.
The phone does not actually give me a "LOCKED" message, and it partially works T-Mobile, it just does not pickup all the LTE bands, so it only has a connection about 50% of the time. Tmobile recently changed their bands, a month and a half ago it was working perfectly. The main goal is to turn on the locked bands.
If I'm understanding correctly if I take the phone to Korea, use a sim card from there on it, and make calls, then I go back to T-Mobile it will trigger the unlock mesage, which will allow me to access the LTE bands in *#2683662#??
Have you solved this yet?

Just curious if you found a solution to this yet?
I read all the posts about how a phone branded and bought in Korea needs to be on a Korean simcard for at least 5 min or so before it will accept any other (non-Korean) simcards.
So since I was based in Korea I bought the S8+ (SM-G955N - 128GB/6GB version) in Korea as soon as it was launched in April 2017 and used it with my Korean telecom provider (KT Telecom) for over half a year. In that period, while travelling outside Korea, roaming on LTE in different countries was never a problem.
Recently, I have moved from Korea (to Europe) and got a local simcard (Vodafone - NL). I can get on my provider's network, receive/send calls/sms, etc. No problem, but no LTE! Only some 3G/Edge!
I tried the 'service menu' with *#2683662#, access is possible but it gave back the same:
ServiceMode
Not supported
Mobile: null
Mobile_IMS: null
So first I thought it was related to KT Telecom how their GiGA LTE technology is somehow dependent on the use of a KT Telecom simcard with the KT Telecom network and basically without the KT Telecom simcard, basic LTE functionality would stop.
So I am reading through the different internet forums and advice from other users, but as far as I can tell, I don't think there is any other solution for me then to flash my phone with a less 'Korean-ized' stock firmware and hope this will resolve my problem.
Since, technically my phone is still under warranty, I am a bit taken back with all the extensive 'liability waivers' and step-by-step instructions. Rooting and flashing my phone is my last resort option.
I am just wondering if there are any other SM-G955N users out there who encountered the same problem and made some progress in any other way. Any feedback or comment is mostly appreciated.
I picked up a Korean G930S that had Chinese CSC, and I put an F ROM onto it. The CSC did not change. Here in the US the Chinese CSC worked just fine on the AT&T service getting 4G/LTE. I flashed an XAA CSC (probably not the correct one now that I think about it), which would not connect up.
I restored the phone back to the F ROM/Chinese CSC setup and don't worry about it at this point.
As I understand so far, what ever phone 'ROM version' you have is the CSC you will need to flash, meaning if you have an F ROM for example,you'd need to flash a CSC package that is 'made' for F ROM's. My 8+ went from an International 8+ 955F to look like and ROM function as a Note 8,so I needed a Note 8 CSC if I cared to have that 'match' more specifically to my local carrier, AT&T.
I can't say that the XAA Note 8 CSC works any better than the original 955F International CSC with AT&T, or not.
For my 8+ F, I flashed a Note 8 ROM, and wanted to find a Note 8 CSC (US) package for the phone, as I wanted the CSC to match where I live.
It wasn't really necessary, as the phone had an F (International unlocked CSC sorta thing stock on it) whick worked just fine here in the US. Never the less, I found the correct Note 8 CSC and set that up correctly with an XAA CSC, and it works just fine, as well.

I have family members visiting from Korea, and they have the same phones. I was trying to set them up with US Mobile which is a T-Mobile's MVNO. So initially, I've faced the same issue as you, where I was only getting the voice calls working and no data. I was able to download an app called Force 4G LTE from the app store that let me change the radio network setting to LTE Only (or other options that include the LTE band). That fixed the data issue and I was getting LTE from that point.
The next problem I ran into, however, was the voice. When LTE is on and working I was no longer getting voice calls (both outbound and inbound). And when I switch it to some non-LTE radio band to turn on the 'Edge' signal back, voice worked again. I chatted with a US Mobile's service representative for a while to try to fix the issue -- in the process also tried turning off HD Voice / VoLTE option -- VoLTE wasn't working for me anyways since I am not using T-mobile's service directly. But that didn't resolve the issue either. After many different tries -- I had to eventually just give up and tell the family member to stick to internet calling for their duration of the visit.
The problem seemed to be that the phone couldn't simultaneously use LTE for data and Edge for voice and was connecting to either LTE or Edge for both.
I'm curious about this as my Korean Note 8 did not need local activation, and with all the research I found Korean models are never SIM or carrier locked and do not require regional SIM activation like the F variants.
As far as using a 935N on tmobile in the USA as long as it supports LTE bands 2,4 and 12 it should work fine. Out of the box my Note 950N worked on LTE and by manually enabling IMS and RCS in the IMS Settings app, VoLTE worked too.
I have since created a CSC patch that changes the CSC to T-mobile to make the phone features more applicable, and add T-mobile's wifi calling but I'm fairly sure the S8+ is basically the same hardware as a Note 8 so if all you need is LTE data and voice calling you shouldn't need to flash anything.
To correct a misinformation about CSC per device, they are not platform specific. My T-mobile patch uses a mostly stock 950U T-mobile CSC base, and I can tell you that there is nothing in the CSCs themselves that has anything to do with Exynos or Snapdragon.

I have a SM-G955N Korean model I bought from eBay. Everything works except Mobile Data. I call ATT (my service) got connected with their Advance Division, and they not did help.
We tried setup a new connect under Access Point Names with no luck. I did notice that more ATT type APNs did add to the list of APNs, I tried each and powered off the phone each time, no luck.
My Wi-Fi works just not the Mobile Data. I typed in the Service Mode code which I got from another thread *#2683662#,(thanks XDA Developers), what I got looks like this:
MAIN MENU
[1] Protocol
[2] UE Setting & Information
[3] ETC
MOBILE: null
MOBILE_IMS: null
When I access The 1,2,3 pages I always get the MOBILE: null and MOBILE_IMS: null at the bottom of every page. My guess these are error codes.
Any help or ideas would be great.
Thank you.

Here's some more information about this issue.
https://forum.xda-developers.com/showpost.php?p=81262805&postcount=18
So I recently bought a Sprint HTC U11 off ebay, and at first it didn't work at all with my T-Mobile SIM, all it showed was a full strength signal with a capital R next to the signal bar. I called Sprint and they confirmed it's unlocked, although they said it may still be tied in some way to the original owners account, which could potentially cause problems.
I managed to get it working on LTE, by going into testing mode (*#*#4636#*#*) and setting the network to CDMA/LTE only, but with this setting I can only use Data, no Calls or Text. It is also has Sprint as the provider instead of T-Mobile, and I can't switch on VoLTE (greyed out in the Testing menu).
I tested it with some of the other settings, but anything that turns on GSM makes it glitch out, connect for only a few seconds to either T-Mobile or U.S Cellular (a provider I automatically roam on where I live), and then disconnect and refuse to reconnect to anything until I switch back to CDMA/LTE and reboot.
Is this a common problem with the Sprint version of this phone? Are there any fixes for it? The phone is currently not rooted or modified in any way, and is running Android 8.0, Software version 2.33.651.10.
Thanks for any help.
