Since this is a 3G phone and most carriers have stopped activating new SIM cards for 3G devices, please do not activate a new SIM card directly on this phone, or provide the phone's IMEI number when purchasing a new SIM card. If you are activating a new SIM card, please provide the IMEI number of your old phone or any other phone to get the SIM card activated. Then put the SIM card back into our phone.
