Don't buy the unlock code on Other sites, you only have to do just one phone call or online chat
can u check if this work on Tmob 3g? does it have both 1700 and 2100 frequencies? I know it has the 1900 and that's not present in all tmob areas (re-farmed areas)...Call them, submit IEMI to wait for 5 minutes to record the unlock code is so simple
