Do you have cash credit on your account to pay for international calls?
International calls are not covered by plan bundled call minutes.
Are you using the correct prefix - e.g. 00 44 ...?
Note that calls to Northern Ireland landlines dialled using the 048 prefix instead of 00 44 ... are treated as Irish national calls and thus covered by plan bundled call minutes.
