GOOD TO KNOW
Questions travellers ask
Which United Kingdom network has the cheapest roaming day pass?
Of the daily charges we verified, O2 has the lowest: £7 per day (days used) (O2 Travel Bolt On (Pay Monthly)). Zones, plan dates and allowances differ, so compare the destination lists on each official page.
How many United Kingdom mobile networks are covered here?
We track 21 United Kingdom networks, with 9 verified roaming prices. Each one links to the operator's own roaming page.
How can I avoid roaming charges on a United Kingdom SIM?
Turn Data Roaming off on your home SIM before you land, and use a prepaid travel eSIM for mobile data. Calls and texts on your home number can still be charged, so check your network's rates or turn the line off if you do not need it.
Which United Kingdom networks have roaming options for Europe?
Talkmobile; Vodafone; Three; O2; VOXI and Honest Mobile list Europe roaming options. Whether Europe is included in your allowance depends on your plan and when you joined, so check each network's page here.
What is the cheapest way to use mobile data abroad from United Kingdom?
For trips of more than a couple of days, a prepaid travel eSIM is usually cheaper than a daily roaming charge: you pay once for a fixed amount of data. Keep your United Kingdom SIM for calls and texts with its Data Roaming off. Use the comparison on this page to check your own trip.
Why is there no price for some networks?
We only show a price confirmed on the operator's own website. Where roaming depends on your contract or zone, follow the official link to see the price for your plan.

HOW WE CHECK
Every price links to the operator
The operator explains its roaming rules, but not as one fixed price — for example, inclusive roaming that depends on your plan.
The plan exists, but its price depends on your contract or destination. Use the official link to see yours.
Recorded in an earlier research pass and not re-checked yet. We show the plan name and terms, never the old price.
A blank price means we could not verify one — never that it is free. Prices include or exclude tax as the operator publishes them. Snapshot: 25 October 2026. Logos are trademarks of their owners and identify each network only; Graba SIM is not affiliated with these operators.
