Sim Card not recognised.

Hi
I have an HTC 816 single sim and it does not recognise my EE pay as go SIM card. The phone is an Asian version which is Sim unlocked.
I installed CM 12 and after the installation the SIM card stopped working. the card is working OK in my Apple iPad Air so it is not the sim that is at fault. Any ideas on how to get the slot to recognise the Sim Card.
Thanks
