All O2 mobile plans come with inclusive data roaming capped at your inclusive home allowance or the 35GB Fair Usage Policy, whichever is lower. Roaming also includes making and receiving unlimited calls and SMS locally in the roaming destination, as well as making unlimited calls back to the UK whilst roaming in Europe. O2 is ideal for those who travel often or simply holiday in Europe as you don't need to worry about roaming charges. In addition, all O2 mobile plans include an allowance for making UK to Europe calls and SMS - for 20GB and 50GB plans, it's 500 minutes and 500 texts per calendar month; for the Unlimited plan, it's 2000 minutes and 2000 SMS per calendar month.

If you're interested in inclusive international roaming to 29 international destinations such as the USA, Australia, Canada, and New Zealand - as well as inclusive roaming in Europe - you can go for our Vodafone Unlimited plan.
