Default Problem: SMS, Calling & Internet

The phone is a magic duuh its branded vodafone and is been unlocked due Emei code. I'm using a Hi simcard.

Here's the problem:

When im using internet i can't be called, receive sms or send sms.

When i dont use internet everything works fine.. now dont say: dont use the internet because its a pain in the ass!

Thnx!


New update:
Have called service desk of my internet provider..

They have told me that the problem was software with htc.

called with htc.. they told me that they could not help me because it was a vodafone magic.. they said call with vodafone and repair the phone?????
what does that have to do with this problem?

help plz!
