I am trying to hook up an iPhone 6 A1549. MG632LL/A. iOS 9.3.2 The carrier says metro pcs which is my current carrier. I checked the Imei before I purchased the phone and it says it can be activated. So I took it to the metro store and asked if I could swap my handset I bought a new SIM card and tried to activate the phone but it doesnt go through. Sim stuck Searching... Any ideas of what could be wrong would be greatly appreciated. Thank you
