Where did you buy it?It sounds as if the phone is blocked.

Sounds like a possible imei bar has been placed on the handset. Use the checkmend website to check the imei status.

If you find that there are no issues reported in your area, try:
1. Turning your phone off, then wait five minutes, then turn your phone back on again, then wait five more minutes and try using it as normal
2. A manual roam - there's a handy guide for this at http://is.gd/manualroam

but it maybe your phone is locked

John,

What does your o2 coverage look like? o2 banner? 5 bars?

I have seen issues where you still get the o2 banner but no bars and have internet access on an iphone 4s

Returned to the o2 shop and got a brand new phone sent back after it went off for repair.

Who was the original provider for the phone? Is it an unlocked phone i.e. you can put any sim into it?

Seeing as it's an iphone 5 i would presume this is still in hardware warrenty and could prob be replaced if its an antenna issue.

It does sound like your phone has been blocked possibly because the previous owner has defaulted on a contract or reported the phone as lost/stolen

you can check the IMEI here:  http://www.checkmend.com/uk/   It will cost £1.99
