    I just got my HTC Wildfire Pay As You Go on O2 this morning. At first I was able to see my credit balance but now every time I check it keeps saying, "Connection problem or invalid MMI Code.". I am unable to send or receive calls and text messages. When calling, it beeps once and hangs up and when someone tries to call me it redirects to voice mail.
