    Hi,

    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.

    Help?

    Thanks,
    Andy.
