We need more information, but I'll give it a shot. Assuming that your Diamond is a CDMA version and not GSM ... have you unlocked the phone? If so, then you might try flashing a new radio, such as the Sprint or Telus radio that is noted in the stickies in the Diamond upgrade forum.

If you have not idea what I'm talking about, pm me and I will walk you through it.
