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.

Go to the Howard Forums Straight Talk section and ask this question. They can help.
Courtesy of a very good deal while I was in the USA, I was able to pick up an HTC One M8 for $100. Seemed like a great deal for my first Android phone running 4.4.2. Talked with their support people, to guarantee it wasn't locked, confirmed that with a couple of web sites, then bit the bullet. Now I am back in China, using China Telecom, which is compatible with respect to data transmission, and both voice and SMS works fine.
But data, with a 4G SIM, doesn't work at all. Nor does 3G, or 2G. Oh yes, we have no chickens (G in Mandarin sounds like 'ji', which means chicken). Investigating things, it seems that this is because in trying to configure the phone APN for China Telecom, there is a required field which Verizon doesn't display: PPP. Without a way to set up PPP field to #777, there is no way to get the phone to talk China Telecom's network. Additionally, even when I try to save the APN information, it resets fields like MNC (CT requires 03) back to the Verizon value of 11. WTF? Obviously, it is time for me to venture into the world of a custom ROM, since that might make all the things I need visible. Decided to go with Android Revolution ROM.
I rooted my device with Weaksauce, downloaded all the required files, and was looking into custom recovery when Verizon pushed to me that an upgrade for my phone was available (4.4.3). Decided WTH, maybe that will expose the PPP entry that I need.
Nope, Weaksauce no longer works (and I didn't get to the point of S_off before that happened). the APN menu is now completely locked (with no ability to change anything or create new APN entries), and now I am concerned that Verizon has hosed my ability to get this phone working in China as anything other than a wi-fi capable data machine.
As a first timer delving into this world, I would appreciate some quick pointers to make sure I am going in the right direction.
Thanks in advance.

You might want to post in the Verizon HTC One M8 forum, this is for the M7.
I've got an AT&T M7 which I'm trying to use on T-Mobile. I've carrier unlocked it through AT&T and, with the T-Mobile SIM in, I am able to get "data". Data is in quotes there because even though I see bars I can't actually get anything. Also calls and MMS don't work. SMS works reliably though.
I've made sure the only APN is one with the settings specified on T-Mobile's website.
I saw someone on the T-Mobile help forums recommending flashing with the T-Mobile flavor RUU offered on HTC's site. I downloaded it, but it doesn't seem to recognize my phone (I assume because it's checking for some sort of T-Mobile signature?)
Anyhow, if anyone has dealt with this before, I'd appreciate any advice.
For reference for anyone dealing with this in the future, it ended up being something on T-Mobile's end. They had me turn the phone off while they reset something in their infrastructure. When the phone came back up, it was able to call.
This has been a frustrating issue. My wife and I both have Nexus 6 phones. She has the 32gb & I have the 64gb version. Hers recently started not receiving MMS messages. Anything with a large picture would simply never show up. Anything with a very small graphic or group text would show up as "Non-text content". Here are the steps we've taken to solve this:
1. TMO started by insisting it was an APN issue. So she edited her APN. Didn't help.
2. We then swapped SIMs. Hmmmm. My phone then behaved like hers while hers could then send/receive MMS.
3. TMO said ok maybe it's the SIM. They sent us a new one. SAME result. Her phone wouldn't receive MMS.
4. Out of frustration, I factory reset her phone and reset the APN info. Didn't help. (Cleaned up her phone of some trash programs though. :laugh
5. TMO engineering says they still can't find anything on their end. Elevate to tech supervisor. She tells us to go a TMO store (right near us) to try a THIRD SIM. OK, we do. SAME RESULT. We tried swapping SIMs around again and the same thing happens. My SIM in her phone, everything works. Her SIM in mine, I can't receive MMS.
6. TMO store guy suggests MAYBE (but unlikely) that there is something her account has that's stored on the SIM when its activated that causes the phone to freak. Also says it's above his pay grade .
So now we are again waiting on TMO to poke around further on their end. My question for all you smart types here is:
Has anyone ever heard of this issue? Is there anything you know of that could be causing it? I think it's a bad provisioning somewhere in the dark recesses of TMO. The ONLY change we made to our plans (which seems just coincidental) is that we moved from the 2 lines Unlimited for $100 plan to the over-55 Unlimited plan. We did this maybe 3 weeks ago. But the features are all the same on both plans.
We are both on the same Android 7.0 final OTA firmware updates from Google. NBD92G
Would there be ANY chance that a sideload firmware update would make any difference? We're getting desperate here. Any & all suggestions welcome.
I wonder if her SIM is configured for wifi calling. There has been a conflict between wifi calling and mms for awhile. I've seen it reported several times where this T-Mobile forum post helps in that case
Don't use old firmware... I had issues on certain custom ROMs and old firmware where MMS wouldn't work over WiFi. Never as bad as you were getting.
If you wanna stay stock, sideload the latest OTA to go to NGI55D. Anything older than that is vulnerable to Blueborne exploit, which is a HUGE security concern IMO. I can confirm MMS is working correctly (even with WiFi enabled) on bone stock NGI55D as well as custom ROM Dirty Unicorns v11.7.1 which includes September security patch.

I've had this issue on most LOS roms. i ended up making a custom APN i flash when i try a rom built on LOS.
Yeah, it sure sounds like a problem with account partitioning, or something else with the account that gets associated with the SIM on initial use. What if you try the problem SIM in a phone that is not a Nexus 6? I wonder if you could get a new sim and set it up in a different phone, then transfer it to the problem phone?
OK all, finally got a TMO engineer who agreed with my assessment -- that it was a hidden provisioning problem. She nuked my wife's line and recreated it from scratch. Everything works great now. Frustrating that we had to go through about 15 phone calls and over 3 hours of phone time to get it resolved.

Glad they figured this out.
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).
