So I bought this iPhone 13 Pro from Facebook marketplace for cheap and tried countless times to unlock this phone. No, it is not blacklisted and it seems it has all the requirements. Ive called tmobile maybe 5 times today and have gotten different answers, one is is cannot be unlocked because I have to go instore, another they sent a unlock request because it met the requirements but had no way to notify me that it actually worked. Or it was linked to a government account. What is even right??? Im so confused and frustrated. I might aswell just buy one of those r-sims because I'm not switching anytime soon to t-mobile.
