Can anyone advise me on using my bill paid Three Ireland mobile phone in Turkey. I was advised to take sim out and just use wifi. I can't do that because I need to be able to respond to a text sent by aib to verify its myself using my debit visa card within 4 hrs or they could freeze my card! They no longer give you the option to put in a travel note before you go. I find this frustrating because id rather not use the phone for fear of running up a huge bill accidently. Yes I can turn off data but I'm unfamiliar with how phones work! What charges could I incur if I get phone call/messages? Can the phone turn on data automatically? Any advice welcome! Is there an add on that I could avail of with three?
