International call

[NK23]

It is not letting me make international calls

Check you have not got a Spend Cap in place by contacting O2 - the cost of the international call (they are not free) will push you over any cap.

Less likely, but possible, is if you have an international calling bar: Guide: O2 BARs - again contact O2, Social Media Team links are in the link just below. Good luck, @NK23.
