Calling, texting and data usage abroad - Pay Monthly

Whether you're calling abroad or travelling abroad, we can help. If you want to call overseas, we have a range of international calling plans and Bolt Ons. If you're going abroad, you get wide network access around the world with O2, helping you to keep up with friends and family while you're away.

Information on calling, texting and data usage abroad if you're on Pay & Go can be found here

Travelling abroad

You can use your phone on over 400 networks in more than 200 countries to make and receive calls, send texts and use data.

If you're travelling in Europe then you can take advantage of the great rates for calls and internet use with O2 Travel

Our standard rates for calls from abroad and a selection of Bolt Ons can be found here. Simply type in the name of the country you're travelling to, followed by the name of the country you wish to contact. You can then see a range of costs for both Pay & Go and Pay Monthly users.


If you're travelling in Europe on our standard rates we'll cap your internet use at £48 (inc VAT)/250MB. If you're traveling outside of Europe, we'll cap your usage at £40 (ex VAT)/50MB. Terms apply

You can raise this cap to £120/630MB in Europe or 200MB outside of Europe by contacting us. You can relax knowing you'll never pay over a specified amount. Terms apply

If you want to use more data, you can remove the £120 cap by contacting us. Once the £120 cap has been removed, you'll be charged per MB for the country you're travelling in. You can find out more information on cost per MB here and our Demystifying data help article explains data consumption.

If you want to reapply your £120 data cap contact us when you're back in the UK.

If you have apps on your phone, some of them may connect to the internet to update or get information even when they're not being used. If you don't want to be charged for data usage while abroad switch data roaming off on your phone before travelling.

Using Voicemail when abroad

Voicemail 901 is available to all O2 customers and is ready to go on all new O2 phones. Before you travel, you’ll need to make sure you know your pin, so if you have not set this up or it's been reset, see these instructions for setting up your voicemail pin.

When abroad, just call 901 as usual. This will work in most countries but where it doesn't, call 1780 free from your mobile, or +447802 090 100, and we'll send you a text with the correct number to call for voicemail.

Depending on which country you're in, you'll either go straight to your messages or you'll go to your voicemail greeting. If it's your voicemail greeting, press * and enter your PIN.

If you've forgotten your PIN, you'll need to contact us and ask for it to be reset. You'll then need to change your PIN before you can listen to your messages.

You can find out more information on setting up your personal greeting and how to check your messages in our help article.

Charges for Voicemail when abroad

To retrieve a message

It will cost the same as a call back to the UK.

To receive a message

If an unanswered call is picked up by your voicemail while you're abroad there is no charge on your mobile bill for the message left.

Charges for calls made while abroad and your bill

We'll try to include your overseas call charges on your next available bill to help you keep track of your cost. However, sometimes we receive the details of calls made from another network late and this may cause issues with timely billing. This very rarely happens, but is more common from countries with smaller networks.

Accidental roaming and how to prevent it

Accidental roaming might occur if you're in an area close to national borders and your phone picks up the network across the border. If this happens, you may be charged as though you were roaming in the country across the border.

You can prevent this by setting your handset to do a manual network selection as opposed to an automatic network selection and select the O2 network. This way if you lose the O2 network, your handset won't try to connect you to a different network.
