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!
Hi all,
Received an Olympic edition note 8 (n950n) at the Olympics. We were supplied originally with a KT sim and even in the settings there's a "service provider" menu of KT related items. I have gotten back to North America and popped in my TMobile sim. It took resetting all network settings until I finally got LTE working on it.
However, volte doesn't seem to work at all. I even downloaded the shortcut master and went to ims settings to enable volte switch but still switches to 3g when I make a call. Similarly it can't even find hd calling. The option in shortcut master "hd voice" shortcut says "not found" when I try to launch it.
Ideally it seems as though I just need a different CSC but I don't want to void any warranty on this phone, especially given that I'm sure Samsung USA won't touch it since it's an international model.
Are the n950n's just lacking in many features?
Thanks!
I dont know how your carrier handles VOLTE, but my carrier requested me to go in person and there they activated the service

Hey There,
I'm glad to stumble upon an actual user of an Olympic edition.
Would you mind installing Samsung PhoneInfo app from playstore and sharing your current CSC Code, and your Device Model number - which I assume is N950N ?
I'm just looking for a way to obtain the bootanimation and the theme of it...

Short answer, sell it and get the USA version.
Sent from my SM-N950U using Tapatalk
Don't want to sell something that has such sentimental value to me
Product code SM-N950NZWZKTC
CSC code KTC
Additionally it doesn't seem to have the ability to have conference calls?
If you enabled all the switches through IMS setting & VoLTE still doesn't work, you'll need T-mobile CSC to get it working. Aside from the IMS settings, there are some VoLTE related settings in cscfeatures.xml. I have a N950F with modified T Mobile CSC, VoLTE, Wifi calling are working fine, I also have the VoLTE quick setting tile. But I'm rooted & is how I installed it
You'll need T Mobile CSC for wfi calling.

Heck no, I say root it, I'd never trade it for a US Snapdragon but that's just me. Can easily get VoLTE working along with many more features.

Will the Tmobile CSC work on this particular device? Tmobile csc i thought would not work on the 950n's as its not the same hardware?
where can i get the csc?

That I have no idea, I have no idea if flashing just the CSC file works between different model/chipset phones. I assume not. I rooted my phone in 2 days so I have no experience flashing official CSC files.
I'm using a modified version of TEKHD's S8 T-Mobile transformation pack. It's an early version of the following mod that I further modified for myself.
[MOD] Exynos T-Mobile CSC Wifi Calling, VoLTE etc for N950N / N950F
The person who made it has a N & specifically made it to get VoLTE & WIFI calling to work on N models. I'm using an earlier version cause it works fine on F models but still had issues on N models. To summarize that thread, he finally got it working fine for N models with nothing additional needed. But you need TWRP & root to install it.

It won't replace the Olympics boot screen but it will trip Knox & may void warranty (not sure what warranty laws are from the original COO, some countries don't void warranty for tripping Knox). But if you are in the US, you can't claim warranty on the phone in the US anyway.
You'd have to install TWRP & root your phone to install the mod I linked. But being how rare that phone is, I wouldn't do it unless you find a copy of the stock Olympics FW for that phone in case anything happens. Seems like others have been looking for it but can't find it yet. Other say it's just a theme that can be installed but if it has a different boot screen then I doubt it's just a theme for the theme store.

Maybe you've got the rare paralympic edition of Note8 which isn't capable of it? (I know, tastefully offensive. I'll be going to hell for that joke)
On a serious note, since it's the N950N which is similar to the N950F afaik, you're better off asking TMobile directly about any connectivity issues.
Usually like others have previously mentioned, should be CSC related but f.e. (if I'm not mistaken) due to the OMC folder/ structure, nearly all country CSC are included. Just the CSC features aren't accessible unless you replace the specific CSC with a modified one from S8/S8+.
If TMobile can't fix it or help you out, you're choice would be to root, double check with a N950F/N950N user if they have volte or (someone has to jump in here to verify) try flashing -if available- factory binaries for specifically USA.
I doubt T-Mobile will help or can even do anything being an international phone. My F on T-Mobile USA worked perfectly fine. You don't need IMEI provisioning with T-Mobile USA like you do with some carriers like AT&T. My speeds were great out the box, better than my T-Mobile Note 5, just didn't have VoLTE & Wifi calling until I enabled them w/ root. We now have 2 more Note 8s in the household, U T-Mobile variants. Speeds are pretty much exactly the same as my F.

Hey there, I thought I recognized the name. Remember me? One of the first to test and rip open the F model to try and figure out the LTE issue / carrier aggregation issue.
I've read through some pages over on the OEM Lock thread ... so to conclude, they figured out the issue with the OEM lock disappearing, but did they ever figure out the carrier aggregation for using F/N model 100% on T-Mobile??
I know people with the F and N models that are still suffering from carrier aggregation and like this Olympic Edition model, which is just a N model with a cool back white Olympic cover. Those who plan to use this on T-Mobile may face the LTE connectivity (carrier aggregation) issue..
For those in really good reception areas may not seem like they have an issue, but that is because they are connected to a really strong (single) signal/frequency, which makes it seem like everything is fine...
Would you be able to provide links to any progress regarding this issue? Has it been solved? If so, it's likely buried in the pages somewhere in the other threads....:highfive:

Yes I remember you. I may not be the best guy to answer your questions but I'll share what I remember.
If you remember, I was just about the only guy in those threads that didn't experience any of the issues you guys did. I'm still using an early version of KT's TMO zip which was basically a slightly modified version of tekhd's S8 zip. The versions to follow is when they started changing more & had issues as it was later found out that the TMB_keystrings.dat from N950U was the cause. Once they replaced that file the issues were reported to have been resolved. I think the current version is like 9m or something I like, I'm using 3a & always have been, never tried any later versions & is probably why I never experienced those issues.
At home my reception is not very good nor are speeds, I get 20-40mbps depending on the time of day. This was the same before I used the zip. My CA combos were different than what the zip gave me but I still had the combos that get's used the most in my area. Around town in good areas I can get 80-135mbps. I stopped checking as I put the subject to rest a while ago.
A few months ago my parents both got Tmobile N950Us. I compared my F with the TMO zip & speeds are pretty much the same, sometimes my F is slightly faster, sometimes the U, but not a big difference so I consider that other factors & call them the same. I've even tried a speed test at a local T-mobile store & the speed was like 6mbps (that area I know doesn't have good coverage) on a U where mine was getting just under 20. Still I'm not saying my F is any better but since I was able to test actual T-Mobile U variants, I don't believe my phone to have any issues with speeds & CA in my area.
Yes the Olympics edition is simply an N with a theme applied and physical cover with the logo on it. the bootscreen is an olympics logo etc.
Merging calls doesnt seem possible, i dont know why. LTE frequently drops on Tmobile now and just goes to 3g or no service at all.
Volte not working either.
I had a similar situation. I bought my phone (N950F) from abroad. Although the phone was in the compatible devices list of my carrier company, they told me that VoLTE could not be used on phones taken from abroad (silly reason). VoLTE enable is carried out by sending a request SMS to the carrier. I put my SIM card into a friend's phone, and sent the request through it. My carrier enabled my SIM card. I put it back to my phone and voila! I have been using VoLTE since then without any problem.
Just wanted to post a final kind of update and that is that the above referenced CSC for Tmobile worked well.
I just got my new unlocked S10 all set up dialed in. Model SMG973U1ZBAX.
I put in my AT&T SIM card in and went to turn on Wifi calling and couldn't find it. I've since learned that if you have an unlocked phone, you can USE the AT&T network, but you can't get Wifi calling (which is a must for me), Visual Voicemail or HD Voice.
Instead of flat out returning it, can I just flash the AT&T ROM and it would be as if it was a a stock AT&T phone?
I know I would get all the bloatware and stuff like that, But I have to have wifi calling.
Are there links yet to Stock AT&T ROM for the S10? I couldn't find any on the site.
Thanks

Yes you can there's a thread somewhere in here with specifics on how to do it. I know you have to flash thru patched Odin and make sure you also flash userdata and csc to corresponding carrier.

Root is unrelated to firmware flashing. You only need Odin and the fw package. Your computer may, or may not need the Samsung USB drivers to be recognized.
Samfirm can be used to pull updates. You might find it on sammobile or updato, haven't checked.

Sigh. Well. I can report and confirm that you can not use Wifi calling on the AT&T network with an unlocked S10.
Even though I loaded stock AT&T firmware, and was up to date, it just won't work. Gotta return the phone.
I've been dealing with their advanced tech team for over a week and they said that because the IMEI number shows it's an unlocked phone, the system keeps denying Wifi calling.
We actually got it to work at one point. It was a 3 day process with one of their techs forcing my IMEI number through their system. It worked for about an hour, then their system caught it and kicked out it's provisioning.

Galaxy S10 unlocked ATT firmware question
Hi I recently got Galaxy S10 Unlocked phone on online. At first i didnt get ATT wifi calling options appeared in my phone. Later i followed same thread that has 973U ATT firmware links, and flashed using ODIN. I can see all ATT apps and ATT wifi calling option now but i cannot enable it. When i enable it i got a message saying we cannot turn on WIFI calling on this a device and error code EDS0008. I tried to call ATT folks, but they are saying WIFI calling and HD voice is not supported on this unlocked device. Somehow they are seeing 973U1 as model number, but i had 973U as model number. I tried chaining sim to old iphone and I saw WIFI calling is working with IPHONE, but its just this phone I am seeing error. I am not sure what to do now. Did you see this issue ?
Can you give me exactly about the files you used and post steps to get att wifi calling ?
sorry for posting questions in multiple threads
I have an unlocked S10e and I use T-Mobile and before even flashing T-Mo firmware, I did have WiFi calling out of the box. Change carrier

Hi I recently got Galaxy S10 Unlocked phone on online. At first i didnt get ATT wifi calling options appeared in my phone. Later i followed same thread that has 973U ATT firmware links, and flashed using ODIN. I can see all ATT apps and ATT wifi calling option now but i cannot enable it.

Your best bet is to do an exchange for an AT&T version.
You can Flash the AT&T firmware. But there will be no way in h*** for you to actually enable the Wi-Fi calling feature since they block those IMEI numbers on their servers. YOU HAVE BEEN WARNED. YOU MIGHT NOT BE ABLE TO REVERT IT BACK TO THE OTHER FIRMWARE.

Quick question for ya:
YOU HAVE BEEN REPLIED TO. WHY CAN'T THEY JUST REFLASH THE PHONE WITH STOCK U1 FIRMWARE?

This is absolutely not true. I just switched my unlocked S10 (u1) to the ATTfirmware and Wifi calling is working great with no issues turning it on at all.

That's great to know badbread. Did you use the link https://forum.xda-developers.com/galaxy-s10/how-to/s10e-g973u-g973u1-firmware-links-t3905852 for the firmware files.
I haven't attempted this before so I thought I'd ask before screwing anything up.
Thanks.

Yes, that post and a couple others. Pretty painless process TBH.
I can confirm Wifi calling works, HD voice and a WAY WAY WAY better signal. Prior to flashing to ATT I could barely use my phone on my subway ride home... Now it works very well the entire trip.

I successfully flashed and am now seeing the ATT bloatware but WIFI calling and visual voicemail, etc are saying "OOPS! We can't turn onWi-Fi calling for your account. I'm going to attempt to flash with the clean boot version and see if that changes anything. Did you do anything different or additional to get it up and running. Not sure if it matters but I'm in Southern CA.
Has anyone else been successful in adding wifi calling, hd voice, etc?
I'm using build G973U SF6 with USERDATA_ATT_G973USQU2ASF6.
I'm on a US Unlocked Galaxy 10.

I'm away from the computer I did it on but I used the SAT1 firmware file and then manually updated all the way back up to the June update.
The updating part is/was a major PITA as it wiped the device each time. I'm hoping i'll get OTA's when they are released. Time will tell.
I'm in the Bay Area on ATT and it activated right away on the base february firmware I installed initially. Also I don't think I did any userdata stuff as I don't remember choosing it... I'll update this post tonight when I can check all the files I d/loaded on my machine at home.
Couple other things:
I can't find it right now but I followed a post that stated to make sure the SIM and SD card were removed during the flashing process. Not sure if that makes a difference.

did you ever run the unlocked firmware on ATT or did you flash to att before ever using an active sim? i had heard some speculation that once you run an unlocked phone, then it gets registered as "non att"... keep in mind this is 3rd hand info and hearsay.
edit. i guess i failed to read you short post... i see "prior to flashing" spelled out for me right there....

Any chance you found those other posts you mentioned above? I continue to be unable to get wifi calling on my phone.
By the way for anyone else, while I did not get wifi calling, visual voicemail, etc. I do see an improvement on my cell reception over the ATT network.
Ops sorry, thought I replied.

Hi All, I'm trying to make my T-Mobile Note 9 work on AT&T. Using odin I put on the latest ATT version on my phone that I could find -- N960USQU1ARG6. It boots and works fine, but it shows Android 8.1, I don't get wifi calling or there's no place to turn on VOLTE, and when I say update software it says "software up to date." So, I'm assuming that ATT still doesn't think this is their phone.
Any ideas on how to fix this?
Thanks!

Att has Pie firmware for the Note 9. Just do a search for the newest Pue update and flash it using Odin.

Well, it might. I'd really like to understand what's wrong with it before I flash more.

Well the first thing you could do is do a factory reset, or verify with At&t if it's a feature on your account. Not sure how theirs is setup compared to T-Mobile's Wi-Fi calling. It won't hurt to flash unless you've got stuff you need to backup and have no way to do so.
I don't think anything is wrong with your device. All of the N960U devices are the exact same. The only difference is the software. You don't even need to flash a different firmware for it to put the carrier bloat on the device based on the sim card inserted. It's already included in the Software package on the device, just dormant.
I can't see AT&T Mobility (or any carrier, really) willingly remaining in the trailing position vs. the UnCarrier (who has offered Wi-Fi Calling as a feature (even to their MVNO customers) for over a year - yes, I have had it that long personally) - the only time I don't use it is due to support of the *router* being iffy (some residential routers have issues with Voice over Wi-Fi; the same applies to some business routers).
I went to ATT as well and it took some time for me to see the update to 9. Not sure, when I was with T-Mobile it always showed updates right away. For ATT, I was able to find the ARJA firmware with a CSA7 update that expedited the process. It also took around a day for wifi calling to show up. ATT is just slow to enable things perhaps?
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❣

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).
