Have you had the phone activated with an active SIM inside of it for 40+ days?

Yes, that's what T-Mobile states you need to fulfill in order unlock your device.
If you're not the original owner, they WILL NOT unlock it.
you need to be on t-mobile firmware
Flash back to the T-Mobile firmware with MSM Download Tool, then unlock with the app. Then flash to the international firmware again with MSM Download tool then you'll be able to fastboot oem unlock without issues.

Thinking of buying one of these and want to clarify the process of unlocking the bootloader. From the ebay seller he says it is a T-Mobile phone but is sim unlocked already. He says I will have to contact oneplus to get the bootloader unlock code/token. I don't really want to wait the forty days or whatever I heard it was but it's ok as long as I can definitely get it unlocked eventually and won't be stuck for some reason with a locked bootloader. Thanks for any info you can provide.

I've ran across two of your posts asking the same question. I had done the same thing as you. I bought an eBay sim unlocked op7p. At first I flashed the international firmware to just bypass the whole tmobile bootloader unlock. It worked in the sense that I was able to unlock the bootloader, however I had no service and the phone would not detect my sim (Cricket). I tried another sim with the same results. I had to use the msm tool and flash back to tmobile stock firmware in order for it to work with my sim.
I sent in my request for an unlock token and received it in 7 days. I think the 40 days is only for brand new phones. I would submit the unlock token request and go that route. YMMV, you may very well be able to flash the international software and just bypass it. I didn't have that luck. The 7 day wait wasn't so bad. Hope this helps.

That's good to know that I can get the unlock token if needed. So TMobile doesn't care who you are or that you don't have a T-Mobile account or live in US obviously then?

The unlock code comes from OnePlus. I only had to wait the week and the received an email with a link to download the unlock_code.bin file. To answer your question, not to my knowledge.

I think I may be in the same boat. After fighting with msm I finally got it to flash the international firmware but nowjiy doesn't detect my sim. So you went back to Tmobile software and got the token to unlock but once you did that did you switch back to international or custom ROMs?

I have not flashed back to international because I couldn't get the phone to detect my sim even after updating the international firmware.
I would however recommend that once you flash back to TMobile (using msm) that you do the OTA (settings>system>check for updates)
Currently I'm running unlocked and rooted via magisk. I'd like to flash a custom rom (looking at resurrection) but they say to flash the international rom to both slots first (via recovery like twrp) and I'm not sure if that would cause the sim issue again. I haven't had time to ask about it (if I can flash straight from tmo stock rooted to a custom rom like resurrection). So unfortunately I don't have the best answer there. You may ask around in some of the custom rom threads about just flashing straight from the TMobile stock firmware with unlocked bootloader. If you happen to find out an answer, please pm me and let me know.

Actually I was mistaken. Once I updated the international rom to Android Q my sim started working again and now I am on Bliss and sim is still working. Not sure what is going on with your sim.
Hi I will be ordering a one plus 7 pro
t-mobile unlocked and hate the t-mobile firmware so I want to install the international firmware and was wondering if doing so would remove the unlock from the phone making the phone locked to t-mobile

What is it about the T-Mobile firmware that you hate? IIRC the only difference is international enables dual sim

I just hate the boot logo, bloatware and I heard the international firmware runs alot smoother plus gets updates quicker
Are you asking if the bootloader would become re-locked, or if the SIM would become carrier locked? Are both currently unlocked?
Once you are carrier unlocked you are always carrier unlocked. But flashing international wont make you carrier unlocked. You have to have someone on the T-Mobile side do that for you.

So would the Amazon renewed oneplus 7 pro tmobile gsm unlocked be permanently carrier unlocked?
MSM tool will not relock the sim. The lock is in the efs. And this is not flashed by MSM.so you are good to go. But before flashing ,if you are scared it will lock, you can use qfil or edl.py with the firehose programmer elf .and make a backup of modemst1 and modemst2. With these 2 copyed in the unlocked state ,u will be ok. I have locked and unlocked the sim many times for testing by having backups of locked modemst1 and 2 and unlocked. U can go back and forth all u like.alway back these up ,they will only work for your device. With the same HW I'd.
Info:
I used the MSM tool automatic package to get convert to global firmware. It supposedly bypasses the need for a bootloader unlock code from oneplus.
Anyways if i use the other MSM tool to convert back to stock firmware, it still downloads the global firmware.
Right now my phone is on the latest version of the global firmware updated with the Oxygen Updater app.
My settings do not have the Dim Unlock option but the rest of the network stuff (5G, VoLTE, Wifi Calling, hotspot, etc) work fine. I have a t-mobile sim card activated with a Sprint Plan.
Could sprint do a remote unlock or could i go to a tmobile store and have them unlock it? Or is there some app i can use to get to the setting?
Now that i am eligible i would like to sim unlock so i can ungrey my oem unlock button.
Thanks
Update: ive tried manually installing the APK for T-Mobile's Device Unlock app and it doesnt seem to function.

hi
i have a 7pro t mobile version. i was following a guide to unlock the bootloader and root the phone. until i downloaded oxygen updater and it says the phone cant get updates, had to stop. so. can the phone be unlock?
then I can continue with the guide on how to root it,
or my options are limited here ?
thanks
The SIM unlock aspect needs to be done with the T-Mobile unlock tool built into the stock firmware. Bootloader unlocking can be attained by Flashing international firmware via MSM-- then unlocking as if it were international. However, that will result in the SIM still being restricted to T-Mobile if it has not been SIM-unlocked
Edit: Bootloader can also be unlocked with the T-Mobile software installed, a request can be submitted through 1+ to have a file emailed to you, containing an unlock file to be used while on carrier firmware, called an Unlock Token. However, this process will take a week for 1+ to review, and approve if applicable.
I have a T-Mobile OP 8T that I converted a while back to global in order to unlock bootloader. Recently I paid the full balance on the phone and from reading online it can be unlocked with the T-Mobile Unlock app. I downloaded the T-Mobile unlock app, but its not working on the Global rom. Anyone know how to sim unlock a paid T-Mobile phone or do I need to call to do that?
Try this?
OnePlus: Settings > Wi-Fi & internet > SIM & network, then choose Advanced or Network Unlock
If you want to use T-Mobile device unlock app , you need to go back to TMobile firmware again

Yes, you needed to unlock SIM with T-Mobile's app before you converted to global.
You'll need to MSM back to OOS11 again. After unlocking is successful you are free to upgrade to OOS13 or flash a custom ROM
