No Service - Invalid SIM inserted

[SergioPeeorini]

Hi all, 

i've had my Xperia Arc S aka LT15 since November 2011 and all has gone well until now.

I've not had service for a few days now as when i awoke one morning i was suddenly notified that my sim was not recognised. Obviously it's the same SIM i've had since 2011

I closed the phone down and waited for it to re-start which it did, and again the same message is along the bottom of the phone as follows..

No service - invalid SIM inserted

Can you please advise?

I only have 5 months on my contract with O2, and the phone is still insured also. Could it be that the SIM has been corrupted or possible new/replacement phone?

Regards
