Called Virgin Mobile customer service in advance to make sure that my phone and phone number would transfer to new Virgin Mobile Prepaid service. The customer service agent told me it would, and that I only needed to buy minutes and a Virgin Mobile sim card. I bought $100 in minutes and the sim card and was NOT able to hook it up. My phone wasn't compatible.
I may need to buy a new phone but it will not be with Virgin Mobile. It is quite possible I will spend the rest of the evening submitting this complaint online.
