From www.o2.co.uk/help/international-and-network/using-your-phone-abroad/roaming, checked 26 October 2026. O2 is a trademark of Telefonica UK Limited (Virgin Media O2). Slashtel is not affiliated with O2.
O2 sells roaming in two shapes: daily travel bolt ons and fixed-size data bolt ons. The O2 Travel Bolt On (Zones 1 and 2) covers 75 destinations, including the USA, Canada, Australia, the UAE, Thailand, Japan and India. It is for pay monthly customers, is free to add and is charged only on days it is used. It gives unlimited minutes, texts and data, with data speed capped at 2Mbps, separate from the UK allowance. The O2 Travel Inclusive Zone (Zone 1) and O2 Travel Inclusive Zone Ultimate (Zones 1 and 2) are included at no extra cost on certain plans rather than bought: the first on Volt and Plus plans, the second on Ultimate plans, both with unlimited data at 2Mbps. Neither is available on 30-day SIM only plans.
The daily travel bolt ons are charged per day of use. The Data Roaming Bolt On family is bought in fixed sizes and lasts 30 days: Zone 1 and Zone 2 versions come in 1GB, 3GB and 5GB, while Zone 3 versions come in 100MB, 500MB and 1GB. Unused data on the Zone 1 and 2 bolt ons rolls to the end of the next bill month. Without a bolt on, O2 stops data abroad in Zone 3. The O2 Europe Zone is included on all O2 tariffs up to a 25GB roaming limit, and Turkey is not in the Europe Zone.
A data-only travel eSIM from Slashtel connects to local networks, with network selection automatic, and is installed by QR code before the trip and switched on when you land. It covers 190+ countries and has no phone number, so calls and texts stay on the home SIM or go over internet apps. That keeps the O2 number live for calls, texts and bank codes while the eSIM carries mobile data. Check the table on this page for the destinations where it costs less, and compare the approach in eSIM vs roaming compared. Travellers weighing other networks can read EE roaming and Three roaming.
