My friend currently has a RAZR, but her screen has stopped working. she is going to get it replaced in about 3 weeks because thats when she is due for a new phone, but in the meantime she cannot use hers, so im letting her use one of my old phones. its an lgvx9800 (or better known as the V). I cannot figure out how to activate my old phone, with her phone number. Do i have to take this into verizon, or can i just activate it over the phone?
