Try a different rep and say you will have to switch providers if they can't do it.
They don't want to lose your business!
REMEMBER THO my account has over 5 lines and 5 plus years of being with T-Mobile and about 7 phones fully paid off. Not my OnePlus 8 but they did it for me.
Or you can tell them that you need to unlock it for work because you're a developer and need the network unlock to unlock the bootloader. Tell them it's the ONLY reason you got the OnePlus 8 due to being able to unlock the bootloader on OnePlus phones.

Ask for supervisor if unsuccessful after that, and repeat.

Depending on your account status it shouldn't be an issue.

Good Luck!!!

just ported my att number to tmobile so i can get the oneplus8 half off. but i joined my wifes tmobile account....which has the max lines now (9 i think) and shes been with them since 2006. anyways ill ask my wife to call.

If she calls and asks for this to be done as a courtesy. They will be happy to do it. If they don't, means you got a bad rep.

OnePlus 8
Tried to have TMobile\Sprint unlock the "OEM Unlock" option.

It's greyed out as some of you may know.

They said it was something on OnePlus side...

Can't pm and would love your help

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.

Are you still doing this service, if so I'd greatly appreciate it, if not I completely understand this has been posted for a while and I'm just late to the party.

So.... I messaged them last night via IM on the TMO app and literally said unlock my SIM or I'm paying the phone off and cancelling everything. ....... And it worked. 10 minutes later she responded and said no problemo. Didn't expect that. So my advice, just try and ask them..... Forcefully. Lol.

Did they offer you a temp unlock? Or permanent unlock

Edit :

I am trying right now and they only offered my a temp unlock for 30 days

Edit 2:

I am on chat with a rep and they are absolutely refusing to unlock it permanently because it is still being financed. But u see other people on here getting permanent sim unlocks

Edit 3:

Temp sim unlock will not work but I did find this out.

device unlock override that requires the phone to be in use for 40 and 2 EIP payments be made.

There is a work around to get a permanent sim unlock even when you have financing still.

Unlock request

I know that you’re busy, but I would gladly pay for your time to unlock my Oneplus 8. I’m using a T-Mobile MVNO, but I can’t receive calls on my Lycamobile SIM. I don’t trust the services on Ebay or other sites, so please let me know if you have the bandwidth.

They are doing a permanent unlock. I said if it's not unlocked... Permanently them I'm cancelling everything.
Want even a hassle. But ... My account is about a decade old. ?

    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.

    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
