Frequently asked questions
How much does the O2 travel pass cost?+
The pass costs £7 to start, with a daily rate of £7. You are only charged on days you actually use the data. Home network use in the UK is included in the pass, so the charge applies to roaming days abroad.
Is there a data limit on the O2 travel pass?+
The pass carries unlimited data, and the fair use policy sets no cap on how much you use. The one limit is speed: roaming data is capped, so streaming and large downloads depend on the local network rather than on the volume you have used.
How many countries does the O2 travel pass cover?+
The pass covers 75 countries in total. Named destinations include the USA, Japan, Mexico, Thailand and Turkey, and the reference pricing lists further destinations alongside them. Ultimate Plans include those outside Europe at no extra cost.
Who can buy the O2 travel pass?+
The pass is added to an existing O2 UK line, so it suits current O2 subscribers. Visitors arriving without a UK O2 number would need a separate travel eSIM instead. The carrier behind the line is Telefonica UK Limited, based in the GB.
How is the pass set up before a trip?+
Setup runs through Added in My O2 or by texting TRAVEL to 23336, so it happens inside the account you already hold rather than on a separate app. Because it is a carrier plan rather than a marketplace purchase, the line is provisioned on the O2 network itself.
What happens to roaming inside Europe?+
Roaming in the Europe Zone is already included in O2 tariffs up to a data allowance, so many trips need no extra spend. Outside Europe, the travel pass at £7 per day used covers the listed destinations, with unlimited data on the same network.
What support is available while travelling?+
Support runs through phone, chat and help centre, so you can reach O2 by phone or chat while abroad, plus a help centre and a community forum. Top-ups are available when you want to change what is on the line, and the carrier entity is Telefonica UK Limited.
