I just purchased an AT&T SIM card. How do I activate it?
HI whether you want to activate your phone with AT&T sim card ..Then you must first check that whether your phone is locked or unlocked one …If yoour phone is unlocked one then it will freely accept your AT&T sim without any issues ..Else if your phone is locked to some other network provide then until you unlock your phone you can’t use it with your AT&T sim card ..You can easily unlock your phone using sites like OnlineGSMUnlock.com here they render unlock code for all mobile models at reliable cost ….After unlocking your phone you can freely use it with any GSM sim in any countries….
