I am new to this blackberry (7105t) and every time I turn on the phone I notice that the radio is off and it asks if i want to turn on the radio when I make a call. I notice when I call it, I cant even get the call until I make an outbound call and start the radio first. I am using a pre-paid SIM card and cant find where to turn on radio permanently. Any ideas would be grand. Any info about pre-paid phone service and the blackberry would also be very beneficial. thanks a bunch all
