It sounds as if your SIM card is either expired, not activated or burnt to another number, Try it in another working Orange phone first, and then you can at least rule out a SIM problem.

Restriction code is nothing but the unlocking code for your mobile.
Unlocking your phone just removes the SIM card restriction so that you can use other network's SIM card.
To get the restriction code for your Nokia 2220s model mobile, just visit this site http://www.wickedunlock.com/nokia-2220-slide/rs11wp9/ ,In this site just give your IMEI number , country & network lock after that within a short period
you can get the restriction code for your nokia mobile............I hope this is helpful for you.......

O2 XDA Mini S Smartphone Problem


I had the same issue. The XDA is fully unlocked, the problem is that the phone has never been one which Orange have acquired the correct settings for, they never sold it (to the best of my knowledge). When I had mine unlocked and tried to use it on Orange it would not send or receieve any txt messages. Orange were rubbish and O2 point blank refused to help.
I just bought another phone and binned it.
