No one wants to leave their phone behind when they're abroad. In most cases, your BT Mobile SIM is already set up for dialling or using abroad - you don't need to call us or do anything to activate it.
Once you're abroad, your phone should work as normal so there's no need to use a UK country code to call home.
To get the best possible network coverage, please make sure your handset can automatically select a network. Find out how to do this at www.bt.com/phoneguides >
Does BT Mobile work in all countries?
Yes, with a few exceptions.
There are also some countries where you'll be able to make calls but not use data roaming.
With some international networks, you may have to switch to 3G to get data services.
We can't guarantee that BT Mobile parental controls will work when you use your phone abroad.
Can I choose a different mobile provider when I'm roaming abroad?
For now, there are no alternative roaming providers working with BT Mobile. BT Mobile should give you all you need to roam abroad.
You might have read about something called local breakout (known as LBO) that lets you take your data services (but not texts or voice calls) from another provider when you're roaming in an EU country.
At this point we don't know of any local breakout providers working with BT Mobile.
Can I use my plan allowance abroad?
Yes, in over 40 destinations. Find out more on our calling charges page >
What do I need to do before I go abroad?
You need to use your SIM card in a device that receives text messages; this is so we can send you information about using our services abroad. We'll also send you service messages to help you keep on top of your mobile spend.
Different countries charge different amounts for data, texts and calls. So you might want to check these costs before you travel.
To stop you getting hit with an unexpectedly big bill, we cap the amount of data you can use when abroad to £35. You can change this by going to www.bt.com/mymobile >
You might want to think about a BT Mobile data add-on for when you're abroad. It can help keep costs down because you buy several MB of data in one go so the price per MB is lower. Find out more about data add-ons >
Or you can simply turn off data altogether in the settings section of your phone.
There are other ways we can help you manage how much you spend on your mobile when you're away.
