That just convert's the rom to global but doesn't unlock sim.
You need to have an active tmobile sim inserted for around 3 days then need to call them and ask to unlock the phone. After that, you need the tmobile rom installed and need to go into sim unlock and select the permanently unlock option.

A sim unlock?
Sounds dated;
wouldnt the best option be to be to dial up your carriers support line, or uses their proprietary tools?
If using their app didnt work id assume its locked because of a contract. Afaik thats the only thing stopping you from sim/device unlocking

    Hi everybody,
    It's great to finally "participate" after having found so many helpful posts.
    As so many other people, I was fooled into buying a Oneplus 7 Pro, which I was told, was SIM unlocked.
    Once I got the phone and inserted my SIM, a message popped up saying it is network locked to T-Mobile.
    Here's what I've tried:
    - T-Mobile Device Unlock app did not work.
    (Some kind of error message)
    - Flashed international
    - Flashed T-Mobile again
    - Flashed DP3
    - Unlocked bootloader

    Nothing works!

    One of those websites that charges to unlock phones what's to charge me 90 euros for this, but I know how trustworthy that is. It's a lot of money.

    With so many ways to unlock phones now a days, I'm surprised no one has been able to crack this thing.

    Could it be just a question of time?
    I'm sure someone will soon find a way, or if there already is a way, but I haven't found it, could someone please share a tutorial or a link, something please?

    Sorry about this being my first post, but this is, hopefully just the beginning.

    Thanks to all. ;)

    The reasons behind the unlock are crazy. And why it takes so long is the way the lock is set up.Tmobile and oneplus are using the gsmcore (google apps) to collect metadata to verify the phone is being used on there service and being payed off. The crazy part is it is a full system wrapper were all the apps communicate and controle the hwui . This is the alarm or the simlock monitor. As soon as the wrong sim is incerted the apps are not alowed access to the sim. And to get the unlock each app has to collect the full amount of data and then its used with screenshots to generate a hash for a cert for that app. And then the app is free. Before the unlock can beging all the apps in the hidden whitelist need disconected. There way more to it but this is the basic. Just watch a live logcat on the phone and triger some activitys. There is so much hidden in the apps its crazy.

    How about reprogramming the T-Mobile Unlock APP in a way that it will issue an unlock code locally with a PC and not through the T-Mobile servers.

    Is this a possibility?

    Is there a disgruntled T-Mobile employee who wants to help??? :laugh:

    Can you shar the details on where did you get it unlocked, I purchase mine from ebay too, Im from El Salvador Central America, so I dont need T mobile network but I cant get the local ones to work , I would appreciate it if you could help.

    I have already try all the different steps, Flash international Rom, Unlock Bootloader, OEM Unlocked erase modme with ADB but still no luck.

    thank you

    Yesterday I tried something else, from a video on YouTube for the modem/SIM unlock for the 6T.

    Going through the command prompt in Windows and using the "fastboot erase modemst1" it did not work on the 7 Pro.

    Any ideas as to how to get this command working on the 7 Pro?

    Thanks
