The standard advice is to switch off data roaming on your phone, avoid browsing the internet over your mobile network and use free wi-fi spots. However there are times when you need access to the internet and you have no option but to go online via your mobile network.
My favourite feature is the ability to enter your provider’s cost per megabyte and the app automatically tracks how much data you have used and how much this will cost you.
The app costs just 59p and I saved that within the first day of my last trip abroad.
