I was part of my sisters AT&T family plan and I had recently traded my S8+ in for the AT&T version of the Galaxy Note 20 Ultra SM-N986U. Well sis got fed up with AT&T pricing and wanted to switch. So I was forced into paying off my phone & the 4 of us switched to T-Mobile . Me & my wife have our own plan and no longer part of my sisters. So after unlocking the phone the port went fine but I want to switch my f/w to T-mobiles. Will there be any problem in doing so?

If the phone is unlocked, you should be fine. Both use the same base firmware.
You may or may not get all the T-Mobile features. There is a fix for that if you don't get all the T-Mobile features, but it typically involves wiping/resetting your phone.

No doubt that is what I need to do. I just tried SamMoble stock USA T Mobile f/w with Android 11 using Odin & the phone still see's that it is a AT&T purchased phone at boot.

Did you have the T-Mobile SIM card in it?
If not, it will revert to it's initial build CSC. AT&T in this case.
The other option is to manually change your CSC from ATT to TMB. There are threads here on how to do it.

I guess since its a USA based Snapdragon I cant even root it. Yes I did have the T-Mobile SIM card in it. I have tried 2x with stock T-Mobile fw & it still thinks its AT&T. The working network does show T-Mobile, but I would like to get the AT&T f/w off of it. So I will research how to manually change your CSC.

Hi,
Just curious if the AT&T Lg v10 would work on cricket? I have been buying factory unlocked phones for the past year and half so am a bit out of loop. I know older att phone models worked on cricket but I did see a few cases of it not working in the newer threads online. Just want to check before getting it.
Thanks

You can buy a locked AT&T V10 and use it on Cricket (owned by AT&T). It does not need to be unlocked. Same applies for any AT&T MNVO too. In theory, but it seems youve found people posting that for them their phones haven't worked...

Thanks man. I know in theory it should work just a bit hesitant since ATT has been having a lot of new restrictions with new android phones like bootloader lock.

All carriers used to be boot loader locked. That's not new. And as far as AT&T and T-Mobile they welcome each others phones, they like stealing each others customers.
Verizon phone cricket service
Wanted to share I bought a Verizon v10 off eBay (they come unlocked out of the box) took it to cricket, tweaked a few settings and it's worked perfectly for three weeks now.
Im using my v10 on Cricket right now and it works well! Just wont get any updates unless you use an att active sim card.
My v10 is from AT&T and I currently use it on cricket.
My GF's v10 is from Verizon, and she also uses it on cricket. She just had to set the apn.
I use my locked ATT V10 on crickets network. The only real issue is so far it can't update to MM since I'm not a ATT customer.

do you have the APN settings correct? if not, enter the correct APN, enable it, then restart your phone. it should work.
you can just slip in the sim card and hope it works. find your APN settings...

Good day. I am currently running 3 LG V10's on Cricket. So far, so good. Make sure you check your IMEI number with them FIRST !
Anyone have experience with the V10 on mintsim or textnow
The backstory.... Preordered an ATT Note 7 and had many headaches with delivery / billing. I am now living with my old Note3 using Goggle Voice/Hangouts because of my weak signal (all carriers) at home. I'm using a pre-paid Straight Talk plan when away from home.
I've been waiting patiently for the S8+ and now need to decide between AT&T and T-Mobile for a GSM phone. I plan on paying full cash price and having it unlocked to use a 3rd part prepaid plan (Straight Talk or ?).
I considered a factory unlocked phone (Best Buy, May 9th??) but I am told that those will also have a locked bootloader. Up until the Note 7 I always ran rooted with custom ROMS. I became a big fan of Samsung Pay which I think also means a locked bootloader with no root is needed. Of coarse, bloatware sucks. I had good luck with Package Disabler Pro on my Note 7. I will be using my Google number, if only for forwarding to another number. WiFi calling is a must one way or another.
My Note 7 from ATT let me run Mobile Hotspot at the same time WiFi was enabled. This made it easy for giving my Android head unit in my car Internet access. The T-mobile version at the time needed to be turned on and off.
I'm leaning toward T-mobile only because of my bad blood with ATT. ATT coverage is marginally better in my area.

Yes and also if the T-Mobile version is going to have an unlocked bootloader, flashing T-Mobile firmware should allow you to unlock it through the OS.
But it's highly unlikely it will have an unlocked bootloader, although T-Mobile have supported it, I don't think it's happening.

I get that if you buy a carrier phone and then unlock it. But what about the factory unlocked phones sold in the US?
I've heard that the bootloader on those phones is also locked, but not from a real good source of info. I've also heard international versions do not have a locked bootloader and do not support Samsung Pay. They also do not support CDMA (which doesn't bother me at all).

I'm in a similar situation and my first concern is what bands both phones support. Online it seems AT&T covers both GSM providers perfectly. The info on T-Mobile and its bands is extremely lacking. My second concern is the process of unlocking either fully paid off phone for use on the other. I think I can have TMobile unlock it for me but I'm not sure how it works with AT&T. The easiest solution is the unlocked version but thats not even got a release date set in writing anywhere.

As long you are flashing official firmware from Samsung nothing will break. Knox will not be tripped and Samsung Pay will work.

It is my understanding that all US (Snapdragon) phones cover all bands, including CDMA. That means you could even take an unlocked AT&T phone to Verizon. I'm not used to that! It even has LTE-U which TMo is supposed to be soon supporting.
I am an ex AT&T customer. They unlocked my Note 7, and again with the replacement, without issue. I seem to remember there was a wait period at first. 7 or 14 days?
The thing I'm considering is also the VR incentives for pre-ordering. I can tell you AT&T messed up my Note 7 pre-order. They shipped it on the release day by a slow method. I ended up going to a store and buying one outright and returning the unopened one once it arrived. That caused a billing nightmare that I had to call them every months until I finally turned it in and closed my account.

Can you recall where you read the carrier versions support all the bands just like the unlocked versions? All the info I found from the carriers shows different bands on each model.

You're missing what I'm saying... There will be no unlocked bootloaders on any Samsung S8 phones for the USA. You cannot get one from carrier or factory.
I think you may be mixing up Bootloader unlock and Sim unlock....

I do remember that it was a story about FCC approval of the factory unlocked (SIM) phone. Keep that in mind that it may be the unbranded, factory unlocked phone only, but the article did say they were all the same. The locked carrier phones may not be so flexible.
Other things I've found.. Best Buy SIM unlocked does not get the incentives. Best Buy, and their cheaper price, does not seem to offer a T-Mo phone.
The VR incentive is attractive to me, but is not a must have. At this moment, until I can find out for sure if Samsung Pay will work on an international version, I am leaning towards a T-Mo pre-order. But that is me and my preferences YMMV. I have a major dislike for AT&T.
Looking for where I read it. In the mean time this may be interesting to you.

You're correct that it seems T-mo info is evasive.
Hello,
I would like to know, if it posible to buy the Galaxy S8 from the samsung web page (att version), then unlock it and after that flash the unlocked rom flashing it with odin.
Can someone help me?
thanks.
Just ordered the 955F from Clove...
I'm hoping that missing bands won't hurt my AT&T usage much. Or any prepaid sims I may throw in there.
Will see if the 955U info comes out before my phone, and will decide if I want to cancel.

I want to buy a Note 8... I don't want to get locked into any Carrier, but I want Wifi calling and other options to work... I know that ATT needs a ATT Rom to get Wifi Calling... I may switch to T Mobile later this year...
Can I Buy a ATT Note 8 and flash TMobile Rom? Or Vice Versa?
If so, is there any reason to buy one Carrier's Note 8 over another?
THANKS!!!

Att WiFi calling only works on ATT Rom... So although hardware is the same, not all software is the same. Att also turns off some LTE bands so you cannot use theirs on other networks...
Also, If I take a att phone to t mobile or Verizon, will WiFi calling work?
So, same question, can I simply Odin any rom onto any note 8?

From past experience you can just Odin to whatever carrier software you want. At least you could on the S8 and the S7. I've seen a few people say they went from the best buy note 8 unlocked firmware to the AT&T firmware to enable LTE-A and wifi calling.
I still recommend just buying the model for the carrier you are going to use though. I've had the best experience doing that myself.

I have an unlocked Note 8 currently that I flashed via odin to AT&T firmware and still couldn't get Wifi Calling to work... I got VoLTE to work but Wifi Calling wouldn't activate and didn't bother with Video Calling...
I think AT&T has to whitelist your IMEI for their carrier features to work unlike T-Mobile...
Best to just buy carrier version and then flash to unlocked later if you want. They are all the same phone.

Since att is the most difficult to work with, it sounds like I should buy att then if I switch, I can flash t mobile... That gives me the freedom to move back...
Do we have confirmation I can flash t mobile over att firmware?
Best to buy the one you can unlock easier an cheaper then flash which ever firmware you want, which is what I did. Works great?
How do I unlock my phone to switch carriers

Witch modle would you buy?, I am leaning towards the Exynos, Note 8, but I dont know where to buy it, can anyone drop me a link?

Carrier switching guide on its way...
I'm wondering the same. Thinking about switching from att to tmobile. Would wifi calling and other features work on the tmobile variant if I flashed the unlocked FW? Also, do you know if there are any specific features att or tmobile has removed from the stock phone?
Hi, I have S9+ Sprint and recently I've changed my carrier to ATT. I have paid to unlocked my S9+ sprint and I would like to switch carrier to ATT to use ATT also.
Anyone here know how to covert from Sprint to ATT/TMB?
Thanks a lot

It's been gone over multiple times. Check the various threads. If the sim isn't working, it's not the flash of your phone, it's just not truly unlocked. I've seen a few people saying after paying for a sim unlock, it didn't work. Two things to note:
1. If your on a v3 bootloader your stuck until ATT releases a v3 OTA and Samsung releases a U1 version. There's no V3 U1 or ATT userdata currently. To get any ATT features you need to flash the U1, wipe, and then flash the U with ATT userdata and boot with sim in.
2. If you want all the ATT features like WiFi Calling, there's a few threads discussing the need to have them activate those features on a IMEI phone of theirs. They will not add an IMEI from another carrier.

I've been on Verizon for about 10 months now, but would like go switch to AT&T. I put an AT&T Prepaid SIM into the Verizon S22, and was expecting it to restart with the AT&T CSC firmware, but it stayed with the Verizon software. I even got a message saying that because it wasn't a Verizon SIM that some services would be unavailable.
What's going on? I thought all the US S22 Ultras were the same phone whether it's bought from AT&T or Verizon or any other carrier.
Are you using an esim with Verizon? If so try turning it off and letting att be the only one active and it should reboot. You will still keep all the Verizon apps and logo
Nope, I'm using a physical Verizon SIM. Isn't stuff like the boot animation and 5G icons supposed to change, since it's a different carrier?

Can happen if the firmware you're on doesn't support "BYOD" yet. This is true of earlier releases of phones on U firmware. U1 supports it out of the box, so you might want to consider flashing U1.
Right but this is a Verizon S22 Ultra. It isn't really early I would think. Aren't all the S22's in the US the exact same phone?

Same hardware but like I said U firmware is hit and miss.
I switched from Verizon to T-Mobile. After 2 weeks I was still running Big Red branding. One day I started having issues with cell service and data. I flashed the latest U1 software and have been problem free ever since.
