Bolt Ons

Add data and more to your plan

Bolt Ons for Pay Monthly plans

When you're running low on data, you can top up with a Bolt On. There are even Bolt Ons for calling abroad, or Travel Bolt Ons if you're going away yourself.

If you’re on Pay As You Go, check out out Pay As You Go Bolt Ons.

Data

Stay connected with our range of Data Bolt Ons. A one-off payment gets you data to use within the UK and Europe Zone. If you choose a Bolt On, it will start today and will remain valid for over 30 days.

To add a Data Bolt On, sign into My O2.

Travel

When you’re roaming in our Europe Zone, you’re free to use your phone just like you would in the UK, subject to a roaming limit. Some tariffs include the O2 Travel Inclusive Zone Bolt On, or O2 Travel Inclusive Zone Ultimate Bolt On, which cover roaming in certain other countries. Head to My O2 to check what’s included in your tariff.

While you’re travelling, we’ll send you a series of messages to make you aware of your roaming options. Or check the options for your destination.

O2 Travel Bolt On

Outside our Europe Zone, the O2 Travel Bolt On provides unlimited roaming in 75 destinations for a fixed daily charge. Just head to My O2 and browse Bolt Ons, or we’ll send you a link when you land.

O2 Travel Bolt On

£7 per day gets you unlimited calls, texts and data in Zones 1 and 2.

Data Roaming Bolt Ons

Outside our Europe Zone, if you don’t have an O2 Travel Bolt On, you’ll be charged our standard roaming rates for calls and texts. To use data, you’ll need to add a Data Roaming Bolt On. A Data Roaming Bolt On gets you a fixed data allowance for a one-off payment, rather than being charged per day. Just head to My O2 and browse Bolt Ons, or we’ll send you a link when you land.

Data Roaming Bolt Ons

Fixed data allowance, valid for over 30 days.
