In the EU
If you’re a Pay Monthly customer on an eligible O2 tariff, you can use your minutes, texts and data in O2’s Europe Zone just like you would at home, at no extra cost. A 25GB roaming limit applies, so if your tariff includes more than 25GB of data, you can use up to 25GB while roaming in Europe at no extra cost. Once you reach the 25GB limit, you’ll need to purchase a Bolt On to continue using data.
Outside the EU
Roaming outside the Europe Zone depends on your O2 tariff. Selected plans include roaming in additional destinations, while other plans may require an O2 Travel option or incur additional charges. O2 Travel is available for Pay Monthly customers travelling to 75 destinations outside Europe, including the USA, Australia and New Zealand. It costs £7 per day on days you use it and includes unlimited minutes, texts and data. Roaming allowances, destinations and charges vary by tariff, so check your specific O2 plan before travelling to see what’s included.
