Hi, my name is Tiffany. 
I don't have much money, I'm married and I live in the middle of no where, my spouse has a phone and we only have one car so I don't have much use for a cell phone carrier. I saw some posts for using wifi to make calls, but I was kind of confused since I've never had a smart phone before.
Is it possible to get a prepaid T Mobile or Virgin Mobile phone that has wifi without paying either carrier for anything? I was looking at getting either the Virgin Mobile LG Optimus V or the T Mobile prepaid Samsung Dart.
For example, could I buy one of those prepaid phones and either not activate it with the carrier and still make calls and texts through wifi, or else activate it once and not pay for the plan the next month and still have the wifi work?
I wanted it to be an actual cell phone still and have the option of paying a carrier, if I had the money and couldn't rely on wifi for the month. So I would just use the phone for wifi free normally, but maybe a month or two a year I could pay a carrier to also get regular cell coverage for the month?
