Europe is already in your plan. Past it, an 8-day pass adds data on the number you already have — so you stay reachable, and there is no second SIM to install.
Your plan covers the UK and 41 European destinations at no extra cost — your data, and your calls and texts to UK numbers, work exactly as they do at home. That is all 27 EU countries, plus Iceland, Liechtenstein, Norway, Switzerland, the Faroe Islands, San Marino, Gibraltar, Guernsey, Jersey, the Isle of Man, and four of France's overseas regions: Guadeloupe, Martinique, French Guiana and Réunion. Mayotte is not included.
One thing to know before you travel: your line dials UK numbers only, wherever you are. A call or text to any other number — including a local number in the country you're standing in — will not connect. Emergency calls to 112 always connect.
Fair use applies to roaming data, and the amount depends on your plan — see what's covered. Monaco and Andorra are not in the European zone, which surprises people.
Outside the European zone your line is switched off by default — not just data, but calls and texts too. That is deliberate: it is what stops a trip abroad turning into a bill you never agreed to. A pass turns the line back on and adds a fixed amount of data for a fixed number of days, on your own number, with nothing to install.
A pass starts the moment you buy it, and it cannot be cancelled or refunded once bought — so buy it when you are ready to travel. The two passes cover different destinations, and you can hold both at once if your trip needs them.
Passes cover data only. Without a pass, outside Europe your line can still receive texts, and 112 always connects — but nothing else does: calls in or out, texts you send, and data are all barred, and a call to your number will not reach your voicemail either. With a pass, calls and texts work but are not included: they are charged at the per-minute and per-text rates shown on the pass, up to its spending cap.
Both give you data abroad. Which one is right depends on whether people need to be able to reach you on your UK number while you are away.
Keeps you on your own number. Calls and texts still reach you, nothing to install, and it works on the SIM you already have. Costs more per gigabyte — that is what you are paying for.
Cheaper per gigabyte, and works anywhere without a UK plan at all. It carries data only — there is no number on it to be called on. Your UK number stays on your UK SIM, so if you switch that line off to avoid roaming charges, calls and texts to it will not reach you until you switch it back on. Anything that runs over data, like WhatsApp, works as normal. See travel eSIMs.
If you only need maps and messaging on a trip, the travel eSIM is usually the better buy. If people need to be able to ring you, take the pass.
A pass's data is paid for up front, for a fixed number of days. Any calls or texts you make on a pass are billed at its rates, up to the pass's spending cap, so the most you can be charged is known before you go. If you travel without one, your data simply stops working outside Europe rather than running up a bill — there is no pay-as-you-go roaming to be caught out by. Emergency calls to 112 always connect, pass or no pass.
Your plan covers the UK and 41 European destinationsat no extra cost. Roaming passes for the rest of the world aren't offered on this site.
This site sells travel eSIMs rather than a UK mobile plan, so there is no line to roam on. For data abroad, pick the country you are going to and buy a bundle for the trip.
