Ive recently got back from Ibiza and all my txt were free, i paid for my calls but not very much. Spain my be a different story though as movistar and o2 are both owned by telefonica which is spains version of BT i think
None of your free allowances will work abroad, neither will the unlimited text bolt on. However, if you have any of the free texts left that you get with your line rental, then every text will be four of these. Hope that makes sense!
your unlimited text will not work abroad the text that you have in youer allowance count for international text eg if your tariff is £35 600 mins 500 text and unlim text bolt on - then the 500 will count for international but each text will take 4. and it depends on your tariff regsarding the call cost
it will be 136.17per min to make a call if your on a £30 tariff or lower and 84.26per min to recieve and if your on £35 tariff or higher it will be 80.85pper min to make call and 51.06p per min to recieve
