the solution would be to find someone with a t-mobile sim, borrow the sim/lend them the phone and get the phone unlocked. "Hey, I just bought a used iphone that is locked to t-mobile, which is normally fine, but I'm about to go overseas and need to use it with a local sim card, can you unlock it for me" I've done this multiple times (spread out by years so not abusing anything).
