Being able to browse the web from your smartphone when you're on the go is a great function, whether you want to catch-up on work emails while you're on the train or simply make your friends jealous by posting pictures of how you're sunning yourself to Facebook when you're on holiday.
However, while many mobile phone tariffs include data allowances so users can access the net when there's no Wi-Fi connection, many of us forget that doing this abroad will result in roaming charges. And with the UK mobile networks charging anywhere up to £3 per MB of data when you're abroad, bills can quickly mount up to hundreds and in some cases thousands of pounds.

In fact, "bill shocks" became such an issue that the EU bought in legislation last year that sees mobile phone owners having their bill capped at €50 (£41) when using data abroad. However, that's still money you may not want to be forking out, and doesn't apply if you're travelling outside the EU. As a result some BlackBerry users are faced with the decision of whether to leave their handset behind or not.
However, it's easy enough to switch roaming off on your handset. Here's how to implement it on a BlackBerry.
Open the applications list and select Options.
Press the Mobile network option and scroll down to the data service.
Select Off and then press the menu key and choose Save.
