Roaming in Europe stopped being automatic for UK phones a few years ago, and most providers now treat it as a paid extra or a daily charge. That is not the arrangement here. EU roaming has been included as standard on every UK plan since July 2023, with no additional charge inside the roaming zone. What differs between plans is not whether you get it, but how much data it covers.
The Zone Itself
Thirty countries are named in the roaming zone, and the list is published rather than summarised. It runs from Austria and Belgium through France, Germany, Greece, Iceland, Ireland and Italy, down to Portugal and Spain, and up to Norway and Sweden. Liechtenstein and Malta are in it. So are Bulgaria, Croatia, Cyprus and the Czech Republic.
The practical reading is that a normal European holiday or work trip is almost certainly covered, and the exceptions are worth checking by name rather than assuming. Switzerland and Turkey, to take two obvious destinations, are not on that list.
Plans With a Twelve Gigabyte Roaming Cap
National Plus
Thirty gigabytes of data at five pounds, down from a standard ten. Twelve gigabytes of that can be used inside the EU zone, with unlimited UK calls and texts and a hundred international minutes alongside it.
UK Plan Super Extra
Seventy five gigabytes at seven pounds fifty, with the same twelve gigabyte roaming cap, and a roaming zone that adds India to the European list.
UK Plan Mega Plus
A hundred and twenty gigabytes at ten pounds, twelve gigabytes of roaming, and the same EU and India coverage as the plan below it.
The Plans at Either End
UK Plan Smart
Five gigabytes at three pounds fifty, with a five gigabyte roaming cap. The cap matches the whole allowance, which means nothing is held back from use abroad, though five gigabytes is not a fortnight of holiday navigation and video.
UK Plan Unlimited
Unlimited data at twelve pounds fifty, with the largest roaming cap in the range at thirty five gigabytes across the EU and India. For anyone who works abroad rather than holidays there, this is the only plan on the list with real headroom.
One plan carries roaming the others do not. The Super Extra card on the longer terms lists China alongside the EU and India for data roaming, which is unusual enough to be worth naming. If China is on your itinerary, that is the plan to look at rather than the unlimited one at the top of the range.
What the Caps Mean in Practice
The cap is a ceiling on roaming data, not on the plan. Spending twelve gigabytes in Spain does not end your allowance at home, and the UK portion continues as normal. Allowances are subject to a fair usage policy, which is the standard wording and the thing to read if you plan to spend months rather than weeks away.
Calls and texts are the other half of the picture. The hundred international minutes on every pay as you go plan cover calls placed from the UK to other countries. Calls made while you are abroad fall under the roaming arrangement instead, which is a distinction that catches people out every summer.
Matching a Plan to a Trip
For a week in Europe with maps, messaging and the occasional video call, twelve gigabytes is comfortable and National Plus is the obvious choice. For a fortnight with heavy use, or for someone travelling to India as well, Super Extra adds data at home without changing the roaming ceiling. For extended periods abroad, the unlimited SIM only plan and its thirty five gigabyte cap is the only one that does not require rationing.
It is also worth turning off automatic backups before you fly. A roaming cap measured in gigabytes sounds generous until a phone decides to upload a holiday’s worth of photos over a foreign network, and the allowance was not designed with that in mind.
Before You Travel
Roaming is included on every plan, the zone covers thirty named countries, and the caps run from five gigabytes to thirty five depending on which plan you hold. Pick by the cap rather than the headline allowance if the trip matters more than the month.
Zone membership gains and drops countries between seasons, so confirm your destination instead of trusting memory. Updated lists appear at BlogsBuddy. Roaming terms and caps are published by Lyca Mobile.
