Hi there and welcome to the community.
Firstly,if you could please turn your device OFF and wait 5 minutes,then turn your device ON again,as this can help in most cases.If your issue has not been resolved,check the signal in your area,by visiting or clicking onto the link below.

( still not fixed )

You will now need to perform,a manual roam.

1) Go to your phones "settings".

2)Select mobile network options.

3) Change the Network Selection Mode from Automatic to Manual

A list of available networks will be displayed after a few moments.

4) Select any other network that is not your home provider network. After a few moments you will see "No Service" on the display.

5)Now select your home provider(which is o2) network and change the selection back to Automatic.

Hi mate, if you can access the internet ok but can't make or receive calls, and it's been more than 24hrs since you activated your sim, then it's more likely your phone may be blacklisted if you bought/got it from someone.

What you can do now is try your sim in another unlocked or locked to O2 phone to see if you can make and receive calls and texts. If you can, then the phone is blacklisted.

Check if the phone is blacklisted here:

Costs £1.99

Also check here for any ongoing issues with the network in your area
