First off. try cleaning the sim card and rebooting the phone.

Also contact 02 to ensure your account is ok.

202 if your on contract or 4445 if your on payg.

Who carried out the repair ?

If this continues then I would suggest going back to the shop as they may have disturbed something internally in the phone.
