Fixing greyed out OEM unlock setting on a financed T-mobile IN2017 - OnePlus 8 Questions & Answers

Hey, so basically I bought a clean IMEI but financed (not by me) OP8 5G UW t-mobile edition, and I'm trying to figure out how to SIM unlock it so that the OEM unlock option in dev settings isn't greyed out. T-mobile support told me to try a 3rd party unlocking service, which is what I'm looking into right now. I'm just thinking of doing it off of some seller on ebay with some amount of reputation, but will this fix the issue of the greyed out OEM unlock setting?

I was in the same exact scenario, just do what I did borrow anybody's T-Mobile sim card drop it in and then use the T-Mobile app via chat with support and they'll unlock it.

Try some third party unlocking websites. I used cellunlocker.net and it worked. its about $25.

I tried them - they returned my money - "unable to unlock at present time".
Which service did you use?
I was trying to unlock the Atrix 2 too . Which service were you trying ? Has anyone unlocked the atrix yet? I think i saw a video showing the unlock procedure from one of the service providers.
will one of these from the link not work?

i have unlocked sim on other devices by calling att and having them do it.
someone reported att refusing to unlock their A2 though.
you will need to call and tell them that you are travelling and need to sim unlock the phone. they will do a customer check (see if you're activity with att warrants allowing you to get the unlock code).
doesn't hurt to try
i doubt 3rd party unlocking places will be able to do it at this point.

Identify Pixel 3 variant for OEM Unlocking

I've have just bought a Pixel 3 unlocked from Swappa. It was labeled as Unlocked Google Google edition. I want to root the phone, but the OEM Unlocking switch is grayed out.
I tried resetting to factory settings, using my AT&T SIM card, but the switch is still grayed out.
I revised the IMEI and starts with 35. As I understand, this is a Verizon configuration, but it has eSIMs enabled (as I understand, Google phones have this).
How can I verify that this is a variant or not? And if it isn't a variant, is there something I can do to enable OEM Unlocking?
Thanks in advance.

Does model G020E mean the hardware is Verizon and cannot be bootloader unlocked?

The model is G020E, but does not have any Verizon branding on it; everything just says Google. I was told it was a Sprint phone, but I don't know if that means Sprint sold it, or if it was just moved to Sprint network at some point. Either way, the only branding (physical and software) is Google.
When I go into Developer Options, OEM unlocking is greyed out and says "Connect to the internet or contact your carrier." (Connecting to the internet doesn't change anything.)
From what I've read, there's no way to unlock the bootloader on the Verizon version. Does it sound like this phone is in that group?
Also, I've read some people saying that Verizon will unlock the phone after it's been activated for a couple months. It seems like they are talking about SIM unlocking, but I've also seen claims that people got the bootloader unlocked by just waiting the 60 or so days. Anyone have any experience with that?
Thanks

I Googled the model and it said it's an unlocked model. But once you boot it with that Verizon SIM card in it, Verizon will lock you out of OEM unlocking. Remove your SIM card and factory reset. Go through the setup, then try the OEM unlocking again (remember after you flip that switch, you still need to go through fastboot to actually unlock). Then factory reset again, this time with your SIM card installed.
That 60 days thing is definitely SIM unlocking. It will be a cold day in hell before Verizon consciously allows the bootloader to be unlocked.

Cannot SIM Unlock Brand New Never Activated GM1915

I just bought an open box OnePlus 7 Pro on eBay. It has never been activated. I use Ting, who resells T-Mobile. My SIM card works and I can make/take calls. I have cellular data. I cannot unlock the SIM/Network. Called T-Mobile. Spent an hour yelling at them. The IMEI is beyond 'clean'. They have no record of the IMEI because the phone never had an active contract with them. Bottom line is I can't unlock the bootloader because I can't SIM unlock the device.
I tried the TMO to International conversion via EDL boot mode, but it still has Enable OEM Unlock greyed out because the device is network locked.
Is there ANY way I can network unlock a GM1915 (TMO branded) without T-Mobile? The one thing that came up in my discussion with the (hogtied) T-Mobile rep is provisioning the device with a full T-Mobile service plan at (at least) $75 for the first month which would cover the (less than) 90 seconds I need to unlock the SIM. Even that option wasn't something he seemed confident about and I wasn't about to try it on a whim. They (call center people) just have no way of inserting the record into the database queried by the unlock server.
Suggestions?
**UPDATE: I used a beta of Andriod Q from the OnePlus site and have the bootloader unlocked now, but still can't carrier unlock the network.
Someone just posted a guide on how to convert it to internation, this might be what you are looking for.

Unlocking if you own the device? (T-Mobile)

I purchased the device directly from oneplus website. Paid in full.
I went to the T-Mobile store near me and I put the phone on the network and activated it, then switched back to my daily. Mainly because I want to root/rom and play with it for a few days before I make it my daily.
When I got home, I realized that OEM unlock is still grayed out. Even though the device is fully paid for. I also tried to SIM unlock to no avail.
If I switch back to the 8T tomorrow, can an in-store T-mobile rep OEM unlock it for me while I'm there?
they can only sim unlock it. if you want bootloader unlock (oem unlock) there is a guide here or you can get the unlock code with adb and send it to one plus then they send you an unlock token to use. take about a week.
