Rebooting the phone can help too sometimes.

Hi

Can you clarify what's happened ? Do you mean your not getting signal ?

Check your masts if your not getting service signal http://status.o2.co.uk

Where did you get the phone from ?

If you need a new sim card the process is as follows:
SwapMySim Procedure.
If a person upgrades to another phone and the new phone takes another sized Sim Card then this procedure moves the Tariff and Mobile number from the original SIM card to the new one.
This is the same is a new SIM card is required if a person feels their original one may be at fault.
Any O2 HighStreet Store can perform the swap in store or a person can take the SIM card home or request one via O2 Customer Services. 202 for Contract. 4445 for PAYG. 8002 for Business -> http://www.o2.co.uk/contactus
Sim Swap link -> http://swapmysim.o2.co.uk
Be sure to ask for an Account Specific Blank SIM card as Contract and Pay As You Go versions hold different information.
The Service will stop on the original SIM card which indicates the swap has started. Turning the phone Off and On , or if applicable switching airplane mode On and Off ,with the new SIM card in every 20 minutes or so will typically help the connection to settle.
If your newly sent SIM card is a Nano sized version then another alternative if O2 have not supplied a SIM card adapter kit with it, is to pick this free adapter kit up from any O2 Store ,or order a set for a small fee from one of the auction sites.
