    4. 5p per call for voicemail within UK;
    5. Calls to Customer Service are charged at 5p per call. See for more information. 
    6. Unless a Bolt On or promotional rates have been offered and applied, any calls made from the UK to an international destination, including Jersey, Guernsey and the Isle of Man mobiles and landlines, will be charged at standard Pay As You Go international rates.
