No SIM message

Hello. My ipad2 is now displaying a NO SIM message and under Settings, the "mobile Data" tab will not highlight and says "no carrier" beside it. I've never had a problem before. I'm wondering if it could be due to the SIM being from Orange which has now changed to EE?
Ipad is 13 months old.
Ideas appreciated please!

take the sim card out and reinstall, sometimes this will solve the problem. Freddie

It's possible the Orange SIM card is the problem.
It's affecting T-Mobile too.
