Make sure you can use your phone abroad

International roaming is the network service that that lets you use your UK phone abroad. It is usually more expensive to use than a UK-only service and is not included in most standard 'bundle' packages.

Before you take your phone abroad, you need to be sure you will be able to use it. You should ask your network provider:

• whether your phone is enabled for international roaming - if not they can set this up for you, but it can take up to three weeks and must be done before you leave the UK
• what it charges (the tariff) for international roaming services in the country or countries you will be visiting - rates can change at short notice
• whether your handset will work in the country you are visiting - not all phones work in all countries, especially outside Europe

Check the small print for hidden charges

Remember to check:

• whether you will be charged for receiving calls on your mobile while you are abroad
• what you will be charged for SMS (texts) and data downloads
• whether you will be charged an international rate for checking your voicemail

The European Commission's Information Society website contains detailed information on roaming charges in Europe and lets you compare tariffs. For more information follow the link below.

Getting the best deal for you

Most mobile service providers have fixed-fee monthly packages that offer reduced rates for international roaming. If you travel often or for long periods, these deals can work out much cheaper.

If coverage or call quality are very important to you, you may be able to choose a particular network for international roaming. Ask your network provider whether it offers a choice of networks and how you can change between them.

Consider a local SIM card or handset

If you are visiting just one country it may be worth buying a new SIM card when you arrive. The SIM card will only work on that country's network and you can top it up as you would a 'pay as you go' phone in the UK.

If you are worried about your handset not working at your destination, you could hire a phone when you arrive. You can do this at most international airports.

Be prepared

The basics

 Remember to:

• take an international electrical adaptor for your phone charger plug
• ask your service provider what you have to dial to use international roaming - it may not be as simple as adding 0044 to the beginning of a number to call the UK
• pre-programme into your mobile the phone number of the nearest British embassy, high commission or consulate in the country you are visiting and the phone number of your hotel or tour representative

Keep your phone's credit topped up

If you are using your network provider's pre-paid mobile international roaming service, make sure you know how to use your credit card to top up your calling credit before you leave.

If you are using vouchers, you should buy some before you go, as they may be harder to find abroad.

Mobile phone security

Make a note of:

• your mobile's serial number (also known as the IMEI number)
• your mobile phone number
• the number of your operator's customer services (including UK dialling code)

Keep them with you in a safe place, separate from your mobile.

If your phone is stolen you will be able to contact the network operator in the UK and ask them to block your phone and/or SIM card. They may ask for extra information, such as a password, so make sure you have everything they need before you go.
