My wife and I will be in New Jersey for two months. She will need a phone for that period and I am not sure what is best. I have a Verizon cell phone which we use for all long distance calls also. My wife doesn't have a cell phone and doesn't want one other than the 2 or 3 months we are in Jersey. Her phone will be a New Jersey number since she won't be using it here in Arizona. Any ideas what is best (T-Mobile, Tracphone etc.)
