I had Virgin Mobile for some time, then suddenly I kept paying but no minutes were adding up. I switched to Track or Trak phone. My husband has had it for years. I don't need to text or search the web and such. I bought an inexpensive phone 25.00 and get double minutes each time I add (every three months) I have more minutes than I will ever use!
If you get Virgin Mobile, just be real careful which plan you get and the difference between their "adding time" and adding "minutes". Don't ask me, I couldn't figure it out.
