Mobile phones abroad - Do's and don't's

With networks such as Three introducing cheap deals for Brits flocking to the World Cup, uSwitch.com lists the mobile do's and don'ts to ensure that holiday expenses end on the flight home.

Matthew Wheeler, communications expert at uSwitch.com, comments: "Post-holiday mobile bills are the holiday souvenir from hell. But if you do your homework before you travel there's no reason why you can't make the most of your mobile abroad without a nasty surprise when you return home."

"Think about how you want to use your phone while you're away. The most cost-effective way to make local calls is to buy a local SIM card when you arrive. Alternatively, contact your network before you go to ensure that you are on the best tariff. When it comes to using the internet on your mobile abroad, the best advice is don't do it. While some networks are offering special deals, roaming abroad is still far from cheap. Talk and text is definitely cheaper."

Switch off the data roaming option in your phone settings - or ask your supplier to switch off the voicemail and data services for the duration of your break

Ask your provider to cap data roaming charges to an affordable level

If you have an unlocked phone, then buy a local SIM card when you arrive for local rates

If you know you will be calling home while away, look into buying an international PAYG SIM, such as Truefone

Speak to your mobile phone provider about overseas charges - you may be able to switch onto a cheaper roaming package

If taking your phone for emergencies only, switch it off before you leave the UK and only switch on if needed while away, as charges can rack up every time you turn the phone on

If you want to keep in touch, consider texting rather than calling - it's far cheaper

If you are a Pay As You Go customer, make sure you have sufficiently topped up before you travel

If travelling with someone else, consider taking just the one mobile between you.
