I bought an Iphone6 from pawn shop, it is locked by T Mobile

[iMore Question]

The carrier is Tmobile and they wanted me to purchase a 100.00 card for 72 hrs to unlock the phone, i currently have cricket as my provider, any suggestions?

Will you get the $100 back after 72 hours? If so, go for it. By the way, what kind of "card" are they wanting you to purchase for $100 for "72 hours"?
