AT&T to tmobile questions

So last time I had a Samsung device it was a S3 and I have been using and loving my nexus 6 however it finally got a nasty crack in it so I'm downgrading to a Samsung s6. My nexus 6 was originally from AT&T and I just had to fill out some form online to unlock it to work on tmobile and I plan to do the same with the s6 however i was reading up and someone said their are differences between the s6 on AT&T and tmobile most notably Hotspot and wifi calling are disabled. Is this still true? Will I need to flash a TMobile ROM on my s6? Or will those features be unlocked once I insert my tmobile sim card? Thanx in advance.

LTE Bands on N930P unlocked - AT&T or T-Mobile LTE coverage?

Can I use this att odin rooted stock file For the sprint version n930p I read in the n930v tread that att firmware was flash to a verizon note 7 and opened the att lte bands. What to use my sprint unlocked Note 7 on att.

Well i was wondering the same thing. I saw somewhere if you remove the sim card then from the dail pad press ##BRAND# it removes the sprint settings and then put in the AT&T or T-mobile sim after it reboots so it reads that sim cards info and puts in that info.

AT&T ODIN
The one good thing about the Verizon Note 7 is that it is unlocked. I heard that is not the case with AT&T ...not sure about the Sprint variant. I brought our VZW notes 7 to AT&T when I still had PH1 firmware (spent a week back with AT&T) but mistakenly assumed that I probably should ODIN and port back to Verizon to do the explosive to "non-explosive" Note 7 exchange (we'll see about that non-explosiveness of the replacement phones). Then in an even bigger mistake, I allowed the PHE (green battery) firmware onto my 2 new Notes 7s. And wouldn't you know it, only the AT&T (Green battery) variant is not at this site: http://www.samfirm.net As soon as it posts, I'm going to AT&T since VZW hides the Samsung Cloud and removed the Device Maintenance/Ram Management settings.

Sounds like a great setup. I would be satisfied (now that I lost root) to at least lose my Verizonized Note 7 interface. In light of the news that we're hearing tonight (last evening now), I might be be leaving the Note 7 altogether with full refund and either exchange our Note 7s for 2 LG V20s or go to AT&T or another carrier as a free agent for fear that Verizon will Verizonize the V20 user interface like they did with the Note 7.

unlocked S6 edge (us cellular) using with verizon

Upgraded my s5 to the s6 edge and i'm trying to get it on the network. The s5 has a large sim and the s6 has the micro sim so i couldn't just swap. Went to verizon. took the phones down and there system would not open up my new s6 phone. i checked online and the esn is not black listed but it also says no results found. the seller is trustworthy and said he unlocked it and used it on t-mobile for years, verizons plan was to have me bring in a phone that had a micro sim and would register. they would make a working sim. then switch them right back out.
What are your thoughts suggestions and ideas, i will be calling verizon again be 100 percent positive that if a friend brings down their verizon phone and does it for me that they wont have any issues at all.
I pay so much for this verizon unlimited that it really is a shame they cant get me fixed up, and switching plans is not an option. thanks everyone

Switch carrier for G965U from Sprint to ATT/TMB

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.

How unlock used Samsung Galaxy Book 2 (Verizon) so I can use T-Mobile SIM??

How unlock used Samsung Galaxy Book 2 (Verizon) so I can use T-Mobile SIM??
My friend bought a used Galaxy Book 2, put in his t-Mobile Sim and message came up that stated something to the effect that his device needs a Verizon Sim. Even with this message (as someone said it still worked) it did not get a signal.
He cannot return this as he bought it from some 3rd party he will never see again.
He has T-Mobile as a carrier for quite a few phones and has some sort of lifetime extra device -T-Mobile sim plan he can use so he does not want to move just this device to Verizon.
The question is can this be unlocked by Verizon store? And even if it is and APN settings are changed would it work with a T-Mobile Sim?
I know nothing about these LTE laptops and not sure at least for Samsung if the radio in it is somewhat universal or compatible with most US carriers.
Thank you for any advice.
I appreciate it.
Sincerely
Peter
