Hello
I have swopped the SIM card in my 7210, but although it can then send and receive SMS and receive calls; it cannot make outgoing calls-an error message "Call not allowed" appears.
The phone works OK with other SIM cards and the SIM card works on other phones!
I did try an unlocking code but it didn't make any difference.
The SIM card is an old Cellnet Pay as you Go.
Any ideas please.
Dave
