Have you tried pulling the battery while the phone is on, waiting at least 30 seconds and the replacing?
This is a valid fix for some issues like functions not working.
Please let me know if this works, and if you need any further assistance!

It think it's possible that your carrier added data services but did not reload calling features.
Best bet would be to call them even though the SIM works in the other phone.
Hope this helps! Let me know what happens!
