I am about to do my first long overdue trip to Europe - Barcelona, Paris and UK - and will need to make 10 minute phone calls back to Australia every couple of days and send the occasional email without spending more on the mobile than on the fares! I will only be in each country for about a week and reluctant to have to get a new sim and number for each country. Phone is unlocked Galaxy S Duos and provider is Telstra (Australia). Have done a bit of research and asked everyone I know especially the young ones.... So many options but nothing that stands out as a real winner. Each option that has been recommended seems to come with its own issues or is recommended by one and criticised by another eg Travel sim, Go Sim work well/don't work at all, Vodafone good/terrible, phone card OK but staying in apartments with no phone on site etc etc. Would ideally like to have something sorted before I leave as don't want to have hassles once I am away. Don't want million dollar bill but absolute cheapest not the main issue - reliability and ease of use is the main thing. All advice gratefully received.
