[OnePlus 7 Pro Guides, News, & Discussion] MiRaGEx485:
Official T-mobile Unlock

Hey guys, quick story:

I'm enjoying my new Oneplus 7 Pro but dislike T-mobiles choice of software on it and Android Pie without the mods I need. (root, TWRP, ringer as default volume control, completely blacked out theme, etc, etc.). I went to the T-mobile I purchased it from, and was informed to call customer service concerning getting an early unlock. As a condition of the sale I had preemptively checked with the salesman on whether or not "modifying and putting ROMs" on was acceptable to their policy, and he informed me it would be my phone if bought outright and that I could with it what I pleased. At first I thought I could wait the 40 days, but after about 4 days with it, realized I could not... My bad.

I called 611 with my predicament, informed the nice gentlemen Todd of what the salesman had said about it being my phone and that it was paid for outright, informed him my needs have been more than met by their service and I do not intend to stop my service anytime soon, and that I loved the phone, but... But I just couldn't stand their firmware and lack of customization compared to what I was used to the last 5 years with my two OnePlus Ones that I had owned. (lost one, whoooops... I mean, the stock customizations have come a long way from my first stock kitkat version on the One, but we're all here because we know what can be done.) I informed him I knew of the 40 day waiting period, but that I kindly hoped he could help me eliminate that time frame as I really need this device to operate as I wanted it to as soon as possible. He asked me to hold, while he checked on what could be done.

He came back and informed me that the good news was I could unlock the bootloader! (Well I know, dude... but...) I let him him know that I was aware of that, however I had read that I would not have service unless the SIM was unlocked as well and that was not a chance I could take. Otherwise, I wouldn't be bothering them to do this for me at all! He then said that the waiting period could only be reduced to about 10 more days- 14 days from original purchase (for someone who buys outright- that's important, it needs to be "YOURS!"). I politely made the point that it takes about 2 weeks to form a habit in the human brain, and that for the past 5 years I'd been operating my other OnePlus phone(s) with software that I knew I could get for this one. I even pointed out to him that I knew I could do this "by other non-official means" , but that it was important to me to do things transparently and I respected their policy?but would most likely be returning it if I had to wait. I apologized for being so picky, but pointed out that buying one of these devices outright is an enormous purchase and that I expect to be able to do what I need with it. He then put me on hold once more to make sure he'd done all he could...

When he came back, he asked me to open up the unlock app, and to try hitting permanent unlock to see what it would do... Bam, phone unlocked. Todd, you sneaky awesome dude, youuuu!!! Did I just get a good rep? Did the universe reward me for asking kindly, being polite yet persistent, and telling the truth? Did I just get lucky? I dunno, but what I did get is an official unlock from T-Mobile, which I have to say is the best customer service I've gotten almost anywhere since I started living the "city life" again. Your mileage may vary. Dad always said: "It never hurts to ask" and that in business, "No, doesn't always mean no".

Good luck my friends,

P.S. My reason for putting this here is to hope that others will try it and not jeapordize OP and OPs friends positions. I would think to unlock a SIM for an account it would take some form of authorization with a username. If the system is monitored, it could red flag someone who's done what our corporate masters consider an 'excessive' amount of unlocks, and I would hate to see good people like these willing to do these for us at risk, when we could be doing the legwork ourselves in some instances. Long live the Banditos, but please be careful OP and friend.
