Good news - with our O2 Travel Inclusive Zone Bolt On, available with Volt and Plus Plans, you get inclusive roaming in 27 destinations outside Europe. This means you get unlimited minutes, texts and data in our O2 Travel Inclusive Zone, so you don't have to worry about running out or extra charges. You can also make unlimited calls back to the UK and within your destination (calls to other countries aren’t included and will be charged at standard roaming rates). There’s no upper usage limit on data, but speeds are capped at 2Mbps (that’s fast enough to stream content on your mobile without any buffering). If you’re going beyond our Inclusive Zone, you can still subscribe to the full O2 Travel Bolt On for £7 a day in selected destinations.
