Contact the carrier's tech support number.

But the chances are that something went bad on the motherboard, since that's where the IMEI is stored. If the phone isn't in warranty, ask for an estimate for the repair, then decide whether it pays to repair the phone or get a new one. (If it's in warranty, back everything up to your computer, then let them replace the motherboard.)
