Has the sim been activated ?

If so it could be faulty and you need a new one.

Hi @Stavros
Is it just overseas contacts you're having trouble with? If so check you have put the country code infront of the mobile number.
Please check your allowance to make sure you have minutes and texts available. You can do this by either calling 4444 free, then choose option 2 and 2 again or you can text BALANCE free to 20202.
Hope this helps
Stacey
