Both my teenage son and I have Virgin prepaid mobile phones and before that, I had a Cingular prepaid phone.The minutes never seemed to add up with Cingular.Virgin is always there to answer calls for help like when I initiated my service for the first time and wrongly entered my phone number. They fixed it within minutes.The top up cards are a great value and so easy to add to your phone.Nothing but ease of plans and simplicity of use with Virgin.
