Nokia :: Have Not Been Able To Send Or Reciecve Text Messages?

I have had my nokia E63, it has not allowed me to send or recieve normal text messages. I have only had it for a day, and i have never been able to do so. When i try to send them it saves them into the outbox, but i do not even have internet set up let alone e-mail! and whenever i try to call some one it says "emergency phone calls only!". I bought this phone as a virgin phone, and they said it would be okay to use my curent sim card, as it to is on virgin. I bought the phone on pre paid and the sim is also pre paid. However i cannot send messages, and i recently topped the sim card up before i changed handsets. Do i need to activate the phone or something?
