Limit profile destinations are categorised into underlying levels:
- top level 1, 'UK', has eight level 2 sub destinations
- top level 1, 'International', has several level 2 sub destinations to represent each underlying continent, with level 3 sub destinations to represent each underlying country within continent, and finally level 4 sub destinations to represent carrier types within each country:
Taking the above example, the top level 1, 'UK', would permit calls up to 50,000 minutes per month for any sub destinations under 'UK' with the exception of 'Premium', which is limited to just 1,000 minutes per month. Similarly, the top level 1, 'International', would permit calls up to 10,000 minutes per month for any sub destinations under 'International', with the top level value acting as a overall count for underlying levels.
Please note that 'Limit Profiles Phase 1' was superseded by 'Limit Profiles Phase 2' in May 2015.
