Need to change my zip code. When my other half set up my phone for zip code me he put the wrong zip code in so I can not make or receive calls from my phone. When I wast talking to net- Janet last week she said if I was still having trouble I would have to change my zip which means a new phone number and sim card that would be here in 3 to 5 days. But I do not know where to go to do this. Please help me to get this done.
