I flashed back down to 2.1 just for a clean start, then rooted and downloaded the GalaxyS_Unlock from the market, followed the steps, then got my phone unlocked. Dialed that certain keypad code to double check and sure enough, I'm carrier unlocked. My friend wants to buy it from me since it is unlocked, and he has SIMple mobile. Anybody know if he can get 3G/MMS/SMS/Calling/Data?!?!
You need to look for what freq it uses.
Edit: It seems they use Tmobiles 3G networks. If true you won't ever get 3g on this phone (stuck on EDGE).
But calling and SMS will work?
Yes it will work.
What price would you guys recommend I sell it for?
Not the place to ask that. To be honest prices vary so much on location.
Hey Guys,
I had a problem with Data on Straight Talk. On native AT&T coverage everything works great, but when I am on roaming (Not on AT&T but a partner network) I get calls and text but no data. Other people on AT&T get Data and my same Sim in a Captivate (CM 10.1) gets me data. So something is up with the phone, blocking roaming for AT&T. Any ideas. I have tried every kind of various APN to no avail. Looked at some other stuff like Roaming_Table_PLMN_Blacklist (In com.motorola.android.provider.settings) and other stuff try to figure this out. Has anybody else had something like this happen. I also tried unlocking. I haven't done any of the ROMS, for fear of bricking. Maybe some international person has had a similar issue, I don't know. Can't seem to find anything with search.

Straight Talk AT&T Sim
Thanks in advance.
I use my AHD on ST also, but never roam. I know they don't want you roaming at all, and they disconnect peoples service over it. If you're getting talk/text while roaming I would be happy with that.
In reality,i dont think you can roam on ST,at least i never could when i was with them a couple weeks ago,this happens to me on tmobile prepaid ,i can connect to att towers and make calls and text but cant get data,weird stuff

Not the Question
I know I can access data with ST SIM with my other phone, (Captivate CM 10.1) but not this phone (Atrix HD). Why? That is my question. Something on vanilla Mot AT&T devices is blocking me from getting Roaming Data. Straight talk DOES provide the service with many other users verifying we are on the AT&T postpaid network (Including all roaming partners for voice text & data). If I didn't have another phone that worked maybe I wouldn't care too.
Would ROMs help maybe, because that is about the only thing I haven't tried. If they are close to AOSP then maybe that is the solution. I'm just scared of bricking so I must have a detailed and verified procedure. I don't have SS3 installed yet. I may try this and report back, becuase I think Captivate Stock has the same problem.
I guess AT&T put something in that conflicts with the MVNO and nobody knows how to get around it. I'm hoping somebody does though, that's why I asked, because I don't know, and am out of ideas.
I'll report back once I try this, I guess AT&T put something in that conflicts with the MVNO and nobody knows how to get around it. I'm hoping somebody does though, that's why I asked, because I don't know, and am out of ideas.
I'll report back once I try this, I will figure it out (I hope). There has to be a solution.
ThanksI will figure it out (I hope). There has to be a solution.

Hello,
I just retired my venerable Samsung T699 Relay 4G (RIP QWERTY Keyboard) and, just picked up an unlocked, "refurbished" AT&T Note 3 for pretty cheap (it was sold as an "International" model, so I didn't know it was an AT&T version until I got it). I've had T-Mobile service for the last couple of years, and the big draw, for me, is WiFi calling/SMS; I've installed SafeStrap and been trying some T-Mobile ROMs, but can't seem to get WiFi calling to work. Obviously I've got a T-Mobile SIM card, and I've tried changing/adding APNs, and installing different builds of KitKat (some of which won't even boot - NB4 and NF9 seem to work best), but I still can't get it to work properly. I've been racking my brain and searching the Interspace for the last two weeks with no luck... what am I missing? Is it even possible?
Thanks in advance!
Hello,
As a fellow N900A user on Tmobile, I have been trying to get wifi calling as well.
I tried using a tmobile stock rom with wifi calling baked in (tweaked), but that did not work. I was told that I need to add an emergency 911 address, but even doing this did not do it.
I would think that wifi calling is doable, but something tells me that tmobile might be doing something similar to Verizon. Rumor was that Verizon had a list of IMEIs, and if your IMEI was not on their list, you couldn't bring the phone over to Verizon, even if it were CDMA capable (once again, this is rumor as I cannot confirm this is true).
The closest I have been to getting wifi calling through tmobile was having the settings show on the stock tmobile rom, but that was about it. Maybe someone in the forums has an answer/got it working, but I have yet to see one. I'll keep you posted if I somehow get it to work, but something tells me this won't happen for a while.

Yeah, considering I have zero service with any provider where I live (but 4G LTE 100 yards down the street), WiFi services were the single reason I went with T-Mobile. Considering the Unlocking Bill, one wouldn't think a carrier could block IMEIs from being used on another carrier... but I have a hard time reading the fine print, so there is that.
I've tried several of the stock T-Mobile ROMs, and while WiFi calling was there, it simply wouldn't enable; it would try to enable, but never would. Have you contacted T-Mobile and asked if there are any potential fixes? I'm considering doing that, but am worried that they'll say "Oh, that's your IMEI, looks like you can't use it on our network SORRYABOUTYOURLUCK!"
I have contacted tmobile about this before.
Their response was that they did not know why it did not work. They helped me set up the emergency 911 address, but they said when it comes to other hardware they couldn't give me a reason why it wouldn't work.
I remember dwetherill (sp?) mention that some n900a users were able to get wifi calling on their phones. I don't know if the modem can/will affect wifi calling, but at this point it's the easier thing to test.
I'm on the NJ5 modem - I might try testing out NC2.
Have you tried carl's TMB version of the norma stable rom? Check it out if you haven't. Wifi calling is supposed to connect automatically. I haven't seen it work yet, but I'll keep you posted if somehow I get it to work.

I'm on NC2, and haven't gotten anything to work as of yet... I've been looking for modem threads, but I guess I need to look a little harder. I'll search that ROM out and give it a shot, and let you know if it works with NC2. Thanks for the heads-up! :good:
So I tried NC2 modem, and it is not allowing for wifi calling.
I went to tmobile yesterday to get another line added. Rumor on the tmobile side is that AT&T is working to get wifi calling setup for the n900a's by around April. Take it as a rumor at this point, seeing how it came from tmobile, but the rep made a good point - AT&T tends to follow what tmobile is doing, so who knows.
Here's to hoping they're right.
BTW, I went to the note 4 tmobile forums, and I grabbed a deodexed stock rom. I noticed that there were a few files related to wifi calling (had WFC in the name). I tried playing around with it last night, and I managed to get the settings. It will even go so far as to turn the phone GSM radio off when you select wifi only. It's doing what Tweaked was doing for me (which was keeping the wifi calling option grayed out (enabling). I think I'm still missing a few files to get it to work, but I'll keep playing around with it later and let you know if I have any success.

I wonder how that would work regarding using a T-Mobile SIM in the AT&T phone, and if it could support cross-carrier features like that.
You're a braver soul than I, that's for sure. If I knew anything about what I was looking at/for, I'd be more than willing to help get this nut cracked... otherwise, I look forward to your findings!
I recently bought an unlocked Galaxy S10 SM-G973U on Amazon. Got new SIM card from a Verizon MVNO and activated phone. The phone downloaded Android 12, One UI version 4.0. Firmware Build number SP1A210812.016.G973USQS6HVA1. Service provide Software version SAOMC_SM-G973U_OYN_SPR_12_0007 SPR/XAA/VZW. The problem is there is no menu option to activate/switch on VoLTE which means when I'm on a call there is no internet. I've talked to the MVNO tech support multiple times and was told they couldn't see any problems on their side, or that the SM-G973U does not support VoLTE which is not true. I found on one of AT&T's sites that the SM-G973U needs a software patch to enable VoLTE. I also found a couple of USSD codes but they either didn't work or didn't get me to the right setup screen to turn on VoLTE. I even stopped by a Samsung store and they weren't any help either. They said they could re-flash a stock firmware but it would revert to being locked to a carrier which is apparently also not true based on what I've read on this forum. Anyone know how I can turn on VoLTE or know of an apk file or software patch to enable VoLTE?? Does one of the firmware versions posted online have the patch to turn on VoLTE??
I think the issue is that your phone is showing SPR/XAA/VZW. You say you're on a verizon MVNO (who, by the way?)... but your phone isn't seeing that. It's actually saying it's active for SPRint. The second one, XAA, means it's not able to detect the SIM type... and the third was that it was originally VZW, which you can't change and isn't really relevant. (That's just what the phone was "born" as).
Bottom line, your phone isn't seeing VZW or an MVNO as the active CSC nor the SIM card. In the past, the easy thing was to change the CSC to what you need, but I haven't found a way to do that actively. What's supposed to happen is that the CSC should update based on the SIM card and cell signal you're getting... but this doesn't always happen. I bought two phones - one switched with no issues, the other I could not get it to change no matter what I tried.
That said, the easiest thing is to clean flash the phone with ODIN to a VZW or your MVNO's ROM, so that (hopefully) the CSC updates automatically. You could also consider flashing a U1 (unlocked) ROM, as yours is not technically an unlocked ROM (U means it's a carrier ROM... which may be why it's not switching over?)
Again, I tried all of these on the second phone I bought, and nothing would switch it (my carrier is Total Wireless, which is a VZ MVNO, and actually shows up as Tracfone (TFN). I had to return that second phone and get another with TFN already activated, and that worked fine... so be sure you do this before you drop out of your return period.
Bottom line, you should be able to get this all working... my VOLTE/VOWIFI works fine... just a matter of getting you there.
Thanks. My carrier is Straight Talk which is now VZ. The SIM card they sent me has the wording "Verizon Compatible" written on it. I finally found a document that explains how to interpret the CSC codes and your explanation clarifies my understanding of it. Sound like I'll have to re-flash it. Since it was originally a VZW phone I'm thinking I should flash it back to VZW to see if that works before trying U1.
Dumb question as this is my first time flashing a phone. (I've flashed quite a few other things but never had to worry about CSC codes and bootloader versions, etc.) I don't see VZW firmware on samfirms or sammobile. I see Sprint, T-Mobile, and one listed as USA without carrier info but I don't see one for VZW. Can someone point me to the correct location to download SM-g973U and U1 firmware for VZW? Greatly appreciated and thanks for putting up with my lack of knowledge!
Edited: Found the files on sammobile. Will try the U1 (VZW) first. I'll keep my fingers crossed.

Success! Was able to flash U1. VoLTE is now working. The CSC now shows TFN/TFN/VZW. Much appreciated!!!
Awesome, glad to hear that fixed it easily!
And TFN... I'm a fan there, too!
Hi! I'm having a similar issue with the same model and happy to see someone was able to enable VoLTE. However, most of what you said above is a foreign language to me. Would one of you be willing to give me a crash course in what you did?
Here's my specific situation. Last week (~1/4/23) Tracfone shutdown 3G. My Samsung Galaxy S10 (SM-G973U) says my network is set to LTE/3G/2G. I've read LTE is 4G, but still can't make or receive calls/texts, but data and 911 calls still work. Their tech support is no help.
From reading online it sounds like I may need VoLTE, not just LTE. Hence finding this thread. If one of you would be willing to spare some time to walk me through what you did I'd really appreciate it. In the mean time I'll try to figure out what "flashing" mean in a context that doesn't involve showing body parts
Thank you in advance!!
I'm on Tracfone (they were bought out by Verizon, BTW) - I was on Total Wireless before, which is now Total by Verizon. You might try contacting support again, as they are now VZ, and may have more help to offer.
My S10+ is running 975U1 now, and it works for VOLTE/VOWIFI properly. You may consider getting a U1 ROM installed, and maybe even the VZW (or TFN) version if available - that may get you working.
Did VOLTE ever work for you before on this or any other carrier? What is your CSC right now?

Thanks for replying! I'm not entirely sure if VoLTE has worked previously. I bought this phone 6/2021 and have only haver had tracfone service for it. I did find in my setting that VoLTE calling is set to on so it seems like it should work. Of note, the 4Glte in my status bar has always been grayed out (I went back and looked at some old screenshots).
My current CSC is VZW/XAA/ATT.
I spoke with tracfone customer service yesterday and they had me reset my network setting and now I don't even have data and the 4Glte in my status bar that was previously gray has now completely disappeared.
Their customer service refuses to talk to me now (literally no one answers when it transfers to an agent) or they hang up on me, and no I haven't been rude, but I have told them I'm recording the call.
I bought a mint mobile package last night because I'm beyond frustrated with Tracfone. I'm worried I'll have the same problems with Mint. I'm not sure if my settings are screwed up or if it's just Tracfone. In any case things are worse now after talking to customer service yesterday.
I also notice there was no APN setting on my phone so I updated it today and restarted but no difference.
Thanks for any input!! Much appreciated. Sorry for the novel.
Ok, so based on your CSC, the phone is not seeing the SIM's carrier - it's showing XAA which means it's using the default settings, which is probably why your not getting VOLTE. The active CSC of "VZW" may be ok... depends on which carrier you're on with Tracfone. I think they're VZW only, but I'm not completely sure.
You may want to just get a new SIM card and get that activated. HOWEVER, the problem you'll likely face is that the phone was born ATT (last CSC). This means the IMEI won't match a "compatible" phone to Verizon, and they will flat out refuse to activate it (even though WE al know it will work fine). If you still want to do that, you will have to activate the new SIM on a VZ "compatible" phone, then you can swap it to the S10. Note that VZ complains about this when you talk to them... so don't tell them you're doing this... but I've done it many times and it works fine.
If your actual behind-the-scenes carrier is ATT, then you can do the activation with your phone without issue.
If none of this works for you, you can switch carriers to an ATT MVNO and you should be good to go.

OK some of that was still over my head. I'll see what happens with the Mint Sim... one f/u question now though. You said the ATT means my phone was "born" ATT. I bought my phone off backmarket and it was sold as "unlocked". Was that not true? How can I be sure in the future if I buy a used phone that's not from my carrier that it will actually be compatible?
Unlocked just means it's not locked to a carrier. That is true in your case, otherwise you wouldn't have been able to install ANY non-ATT SIM. So, you did the right thing to get an unlocked phone, and that is what you got.
The issue with compatibility is just the asshole carriers spreading lies. They do this to try to get people to buy THEIR phones, for no reason other than to make money and confuse consumers. The "born" CSC has no bearing on anything, really... neither does the carrier-specified IMEI. In your case, the XAA is good, which means it's a multi-carrier ROM, which works with all USA carriers.
Mint is a good idea - being an ATT carrier (IIRC), that should work and they should help you get it up and running even if they have to activate it. Good luck!
Awesome! Fingers crossed!! Thank you for your time and all the info❣
I'll try to remember to give an update in a few weeks for future readers

UPDATE: Switching to Mint worked like a charm! Once my number ported and I put the new SIM card in, service was instantaneous! I've had Mint for 3 weeks now and the service is so much better than with Tracfone! My calls go through nearly as soon as I hit call, the internet is faster.
I didn't need to do a thing either. No making APN settings, etc. I'm betting it has to do with what you said about my phone being born ATT. So funny because the software(?) is Verizon - shows the Verizon when I restart/power up. I still love my bastard phone
So thankful I didn't buy a different phone!!! Again thanks for all your help @schwinn8
Thanks for reporting back and letting us all know, and I'm glad it worked out well!
Yeah, the carriers pull this nonsense all the time... it's BS. The phones are all the same, only the ROM changes. If we can change ROMs (which we can) then there should be no reason to force users to specific IMEIs. But we know why they do this - follow the money. I encourage people to write to the FTC and FCC about this (I have).
I am contemplating purchase of one of these phones, and tried entering some of their IMEI numbers in the imei checker at https://www.t-mobile.com/resources/bring-your-own-phone , and was shocked to find they are ALL described as "Incompatible".
This is a bit confusing after the articles saying the AT&T and Verizon versions would not work after Jan 2021 but that the T-Mobile version would continue working. I tried looking for a later article saying that support for the T-Mobile version this model was being cancelled but could not find any such announcement.
Is that IMEI checker correct? Or is it because the samples I checked may not have gotten the last modem update installed from T-Mobile?
Is anyone still using this phone (specifically the T variant) on T-Mobile in USA? I'm assuming that last update will be important, but does this still work once it is installed?
If yes to the above, do phone calls work as VoLTE, or is it doing the fallback to 2G?
I've also seen threads about enabling more LTE bands, has anyone done that on this phone? In particular is it possible to add support for B71 (600MHz), or is this radio hardware just too old to allow that?
Thanks much, I would really like to know whether I can use this phone or if I would need to find a different model.
https://swappa.com/blog/3g-network-shutdown/ Your phone is fine.
SM-N910T with 2ETI1 OTA modem update works fine. 4g/LTE Data, WiFi Calling works. Does not drop out of 4G/LTE for voice. SM-N910V w/ MODestROM v11 (6.01 TW-based N910VVRU2CQI2 ) w/ a vzw 2CTI baseband update, has working 4gLTE data, but no WiFi Calling, or VoLTE (falls back to 2g, but I still have 2g coverage here, so it's usable, if not optimum. Here's the thing: on the VZW phone, if I set the the salescode to TMB, suddenly VoLTE works, but the Setup pages/menus/statusbar are screwed up, so it's not really useable. Here's where it gets REAL interesteing. On a VZW phone w/ VZW 2CTI1 baseband, & VZW BL, flashed with a custom TMB ROM (trltetmo_N910TUVU2EQI2_Stock_Deodexed, debloated, but still TW), EVERYTHING works. But it's not stable, it periodically loses 4g/lte. What it tells me is that the VZW h/w is NOT THE PROBLEM. I've been at this all day, everyday since VZW turned off CDMA on 01/01/23 and killed my service here. Be warned: If you go down this path, you're gonna be mostly on your own. A LOT of dead links, 'retired' devs, etc. Everyone except you, me, and three other people here have long since moved on from this awesome phone. I'll help you if I can. I bought an SM-N910T , but the damn usb port is dead. Already changed the charging board, not the problem. It's the mobo. If I could identify the usb chip (if it's not the 805 itself, I'd change it. So I have a phone with no adb that I can't unlock/root. I'd much rather get my VZW phone fully working on TMB, since I'm heavily invested in the MODestROM. Haven't given up yet. But search my posts, you'll hear the deafening silence, lol.
Seeing this forum has so little activity, on 1/21 I ended up getting a used Moto E6 (XT-2005-3 is a tmobile aka carrier unlocked MetroPCS version). While overall this is not as nice a device and has fewer features than Note 4, it does cover what for me are the essentials - removable battery, SD card slot, support for 5.8GHz wifi. Best of all, it supports B71 which will be helpful for, well, making phone calls!
I still ponder someday getting one of these as a hobby device, but that would be second place to the E6 for use as a phone, and won't be for a couple more months yet (too many expensive household issues are taking their toll on my "toy" budget right now).

SM-N910T with 2ETI1 OTA modem update works fine. 4g/LTE Data, WiFi Calling works. Does not drop out of 4G/LTE for voice.

Thank you, this was the part I needed to find out. With that in place, the only thing missing would be the B71 coverage but the E6 is already in place for that.
Re your Verizon adventures, I have no experience with any of that. What I read about T-Mobile dropping support for the verizon version in the last network update is all I know, and I don't have the skills to dispute what they say there. The best I could do is offer some links to threads on this forum but on double checking them it seems you've already been there and got no answers.
The only thing I see that might help you with that is if you could update just the t-mobile modem without disturbing the verizon bootloader. I see you tried that but it didn't stick when using Odin. I don't know if it would be any different using SmartSwitch that seemed to work for MarineWonder as he posted at https://forum.xda-developers.com/t/...pgrade-on-jan-29th-2021.4224237/post-87464609 ?
Then again he may have been putting it on a t-mobile phone rather than mixing with the verizon bootloader so who knows?
My guess since it has been so problematic for you on the verizon phone is that you may need to only use a tmobile phone since that may be the only way to get the last t-mobile modem update. Bummer that the one you bought has a dead usb port. How are you charging it? Is there any chance you could return it to the seller since it came pre-broken? Then put the refund money toward another, hopefully working, tmobile phone? And would that MODestROM work on a non-verizon phone?
The only other thought I had is there are apps to connect to ADB over wifi. Sadly most of these need root. The ones that don't, seem to need at least once using a usb connection to do the "adb tcpip 5555" command to set it all up. . . . how annoying that it is all so circular!
There is also https://telnetd.en.aptoide.com/app?store_name=apps&app_id=59202144 , maybe a telnet connection could do the "adb tcpip 5555" command instead of using the USB connection? Sadly the documentation (at https://waxrain.com/docs/010.html ) appears to be written in Chinese, and I never had much luck with google translate.
The N910T still supports VoLte.. It is still compatible with cellular networks.
