@MB1238 

Some more information would help, like what troubleshooting have you tried...

What Phone do you have? 

Have you changed the APN to mobile.o2.co.uk ? 
Have you paid your bills? 

As this is not customer services you will need to make contact with o2 if the above doesnt work - Guide: How to find help & contact O2
