Roaming & International.

Hi I am going away to Guatemala for just over 3 weeks soon and I was wondering is it possible to use my data there and pay extra since it is not on the list of countries included for free roaming in my plan. thanks

Can I use my phone data whilst at sea. Going from Southampton to Norway?

Hi. Are there any add on's I can add to use my phone in Thailand??

Can anyone tell me why I have international roaming charges when I have turned off roaming on my iPhone before travelling abroad.
