Updated September 2025 including roaming charges and fair usage policies
As part of the ongoing service we offer to our customers, we are on hand to advise you of the best value data plans for use in the UK and abroad.
We’ve condensed the top plans, particularly suited for European use, into an easily comprehensible table below. Our commitment is to provide free and precise information on our website to the best of our knowledge and capability. However, given the dynamic nature of network providers’ terms, we recommend verifying the details directly with the network provider for the most precise and up-to-date information at the time of purchase.
Correct as of September 2025.
(1) Most firms limit the amount of data you can use abroad – see all providers’ fair use policies for full information.
(2) When you reach 25GB, you’ll need to purchase a data bolt-on.
(3) If you joined or upgraded on or after 21 June 2023. Otherwise, there is no set limit.
(4) The lower limit applies to customers who joined on or after 14 March 2023.
(5) If you need more than your UK data allowance, you can buy a Data Passport for £5 for unlimited data in 89 countries.
(6) If you need more than your UK allowance, you can buy a Euro Holiday Booster, which gives you 15GB of data plus unlimited calls and texts to the UK and other European destinations (£2.25/day, £10 for 8 days, £15 for 15 days).
