Please could I order a replacement SIM card. The phone that I inserted it into advised that there was no Tmobile network available. After trying different actions regarding the settings on the phone, I went and bought another SIM to see if it was the phone or the SIM. Suffice to say, the new temporary SIM worked in the phone.
I prefer to keep my Virgin mobile stuff, I am so used to the Virgin number etc that it is a comfort thing 🙂
