I'm thinking of going on vacation in a couple of months, and i wanted to use a pre paid sim card. But when I talked to T-mo they said the phone needs to be paid off before they can unlock the sim. I know there is sites out there that will do it, but I really don't wanna pay 30$ for them to do it. is there anyway i can get it unlocked for free ?

thanks for the advcie 🙂
