I have a Verizon branded Galaxy S8, and I may plan to move to T-Mobile in the future. I know a lot of folks have either flash stock Samsung firmware or T-Mobile firmware, but I read that thanks to a recent update, the phone will adapt to any SIM card that's inserted into the phone. Is this true? Will a T-Mobile SIM work in a Verizon branded phone without flashing the phone first with features like MMS and Wi-Fi Calling?
Would there be any added benefits to flashing a stock or T-Mobile firmware at this point?
Thanks!

For the most part yes they adapt themselves now. Some have to be SIM unlocked but I believe the Verizon model already is. It should say SIM inserted please restart. It will install all the t mobile junk including any volte or WiFi calling. They might have.
I actually put in my Simple mobile sim card into my unlocked Verizon S8 and calling works but im not getting any decent data even tho i live in a area. With good coverage. Would i have to somehow flash tmobile radio? I been corrected the apn settings
Professor may have to manual add the access point. I had to when I did a verizon Z force 2 to Att.

I have been thinking of switching to T-Mobile this past few weeks. I would be unlocking my phone and inserting a T-Mobile sim card. But first I would like to know if I can get installed the Tmobile rom on my At&t Note 3 and how? Also will wifi calling and or texting will work?

no you would have to use at&t roms unless you want to brick your phone. you Everything else will work having the right rom and your apn settings corrected.
Check my signature for different roms from tmo or international
Read carefully all
Other working ROMs on AT&T: http://forum.xda-developers.com/showthread.php?t=2938919
I am sure this has probably been asked before but I couldn't find a clear answer.
I have the AT&T version of the Galaxy Note 4. I am thinking of changing my provider to T-Mobile (for a bunch of reasons including I have come to hate AT&T). I know the AT&T version will work on the T-Mobile network as a Smartphone with a T-Mobile SIM. But I have several questions.
1. From what I have been reading, it appears that the AT&T bootloader is locked. Is that correct? So does that mean I won't be able to put in a T-Mobile ROM or a ROM from here?
2. If I can't put in a T-Mobile ROM and unlock the bootloader, how will I be able to get future updates for the phone once I have switched to T-Mobile. I currently have the latest official AT&T OTA release (5.1.1, Baseband N910AUCU2DOI2, Kernel 3.10.40-5613584, etc.). But Samsung has promised Marshmallow for this phone.
Any thoughts anyone? Or should I just break down and buy a T-Mobile phone or a Google Nexus 6P?
Thanks

You can do updates using samsung keis... look into cricket wireless, I hated tmobile, the messed my bills up constantly and the service was iffy... if u have good service with att cricket will be the same for 35 bucks a month. Make sure you carrier unlock your phone with art BEFORE YOU CANCEL!
OK guys, somewhat of a newbie, so try and give me a break. I am looking to upgrade to a Galaxy S8 and came across an unlocked T-Mobile S8. Can I flash the AT&T firmware to this phone? If I run the T-Mobile firmware on the AT&T network, I assume I won't get any updates? What about the radios? I know both are GSM networks and with both the AT&T and T-Mobile S8 sharing the same model number, I assume this won't be a problem.
Anyway, any guidance is appreciated.
Thanks!!!
I'm looking for the same answer
I believe if it's unlocked from t-mobile, all you have to do is put your sim in it. Given they are both GSM and all the relevant info is stored on sim card and not the phone
Sent from my Samsung SM-G950U using XDA Labs
you will still get updates from t-mobile. i am using a note 4 unlocked from tmobile on at&t for about a year, getting my s8+ tomorrow actually. the only thing you have to do is add at&t apn settings which are easy to find if you google. i would like to know if its possible to flash another carrier and then flash back to the phone's original carrier tho
I bought a note 9 that is currently a SM-N960U1 but my IMEI shows as Sprint unlocked. Is this going to have any trouble on AT&T or Tmobile? The phone works fine right now with an AT&T sim, minus VoLTE and WiFi Calling. Am I going to have to flash carrier firmware depending on who I am with or does the sim card take care of that? I apologize I have been out of the phone game for a few years.

You should have no issues if the device is unlocked. Boot the device, insert sim card, and follow on screen instructions. Itll reboot and change the software compatibility over to the carrier belonging to the sim card you insert.

I put my at&t sim in and it did all that, phone works fine. I just didn't know if I had to flash at&t firmware to get the bands or functions.

Good. All the US Note 9s are the same hardware and software. Just depends on which software is active.??

You have an AT&T sim but VoLTE and wifi calling don't work?
Nope. The options aren't in the settings either.
I bought an unlocked Verizon G8 and I inserted my old xfinity SIM card then factory reset, (which on other phones, converts it to the xfinity variant) but this time I just keep getting the verizon splash screen and I cannot get OTA updates through Xfinity.
Any suggestions or help would be greatly appreciated

Inserting a Sim will not convert it to any other variant. There's nothing you can do

I helped someone else who had a s10e that had verizon firmware. I just put in a xfinity sim card, factory reset. And it booted with xfinity firmware. The G8 wont do that though

Yeah... Most phones will definitely not do that. I'm not sure what the huge benefits from having Xfinity firmware would be though.

I suppose it's not. I'm just having trouble getting the latest updates. The Verizon update assistant only gave me the update before the most current one. Know how I could get the updates ?
I'm using a Verizon G8 on XM. To get updates, you need to insert a Verizon SIM, and after the update put your XM SIM back in.
Galaxy Flagships (S8 and up, if unlocked) has multi-carrier support.
I'm sure none of LG phones does that yet.

What do you mean? It's just a matter of supported bands... Depends on each carrier, and sometimes some other hardware matters too, but if the band is supported, it will use it if it can't default to whatever the original carrier's band is

When I meant multi-carrier support, the device converts its firmware to the carrier firmware of the sim card.
ex) Inserting an T-Mobile sim card into Unlocked Verizon Galaxy S8+, then it will reboot and install whatever T-Mobile Galaxy S8+ has (default apps, apns, volte, everything only T-Mobile version has)

Oh. That does not work for all phones though since there's slightly different hardware
