i recently purchased a blackberry online, the phone is from sprint but my network is t- mobile. the phone came unlocked so i was able to use my t- mobile sim card and my phone would work perfectly, but now, out of no where, it's not able to read my sim card. do i need to unlock my phone again or is there something else i can do?
what is wrong with my blackberry?
