I am doing free SIM unlocking on the T-Mobile OnePlus 8. This allows your device to be network unlocked once you choose "Permanent Unlock" on the T-Mobile Device Unlock app or in Settings > WiFi & Internet > SIM & Network > Network Unlock.

ATTN: IF YOU DO NOT MEET THE BELOW REQUIREMENTS OR READ THIS ENTIRE THREAD, DO NOT PM ME AND WAIST OUR TIME, YOU WILL BE IGNORED!

** YES, I CAN UNLOCK YOUR 7 PRO/7T/7T PRO MCLAREN 5G **

Current turnaround time: ~1-3 days depending on how busy I am.

Requirements:
  • Unlocking for T-Mobile OnePlus 8 variant only.
  • Not eligible for MetroPCS users.
  • Device must be on the network for AT LEAST 3 full calendar days.
  • Cannot be on the OnePlus 8 international firmware.
  • Can be bought 3rd party but must be the T-Mobile variant and using the T-Mobile network.
If you meet the above requirements, PM the last name of the account holder and your phone number associated with said OnePlus 8.
Important Information:
  • Please keep in mind I get a lot of PM's regarding this so you will get a reply when yours has been completed. Do not send multiple requests.
  • If you make any SIM card changes, you will have to wait at least 24 hours for me to be able to unlock your device.
  • Your device does NOT have to be paid off.
  • There is no 100% guarantee this will work. There could be a possibility of an unlock ineligibility.
  • The device MUST be one purchased from T-Mobile or a 3rd party but the T-Mobile variant, NOT OnePlus themselves or a different carrier.
I cannot unlock with just an IMEI number or prepaid phones.

ERROR CODE = 255? See below..
  1. Clear your network settings. Settings > System > Reset Options > Reset WiFi, Mobile, & Bluetooth.
  2. Power cycle your device (turn it off and on).
  3. Still doesn't work? PM me your phone number.
  4. I may request you to simply direct message TMobileHelp on Twitter to whitelist your IMEI.

Plenty of vouches here from my OP7T unlocking:

Just got a message that I can unlock my phone. It worked without any problems. You unlocked my son's 7T Pro McLaren in Feb, too. Thanks so much. There's a few bucks coming to your paypal

All unlock requests have been completed. If you didn't get a reply, it's due to you not following the information on the original thread. I don't have time to entertain PM's that ask me to unlock with an IMEI, prepaid, or if you got the phone second hand and don't have T-Mobile.

    I have been super backed up with many requests and such limited time throughout my days with work. I apologize for the delay and will get them done as quickly as possible. Please keep in mind this is a one man army taking on hundreds of requests a day while also trying to maintain a work life. Keep an eye out on a reply via PM with instructions on your device being unlocked.

    For the sake of my time and your time, do not PM me numerous times or asking me questions about whether or not I can unlock your device that you bought from eBay or with an IMEI number. You will be ignored!

    I am disabling my PM's when I'm not doing the unlock services at night. This is to help prevent me from getting backed up again. All requests get caught up then my PM's open again. Keep in mind this is a one man army and I have a work life outside of this. I promise all requests will get done as long as you meet the requirements. For now, all requests have been caught up.

    @An7roid1pro Hello, I've removed your personal information from your post in order to protect your privacy and to prevent misuse. Gratefully, the moderators' team became aware thanks to a report of an attentive member.
    I suggest to always carefully consider what type of information you publicly share on the internet including XDA. However, it's your sole decision and if you indeed wanted to provide these information publicly please feel free to revert my changes. Please be also aware that the OP requested this private information to be only provided to him by private message.

    Stay safe and stay healthy!
    Regards
    Oswald Boelcke


    There's another guy on page 10 that did the same thing. If you could please delete that while you're here too? It's probably too late but better safe than sorry
