No international Calls

Sorry I accidentally set my question as resolved so post again.
I switched the "block international call" off but still cannot make an international call or SMS.
It has been more than 12 hours.
I do not have add-on. Someone said I cannot make international calls without add-on.
I checked the pay as you go.
