Which UK Mobile Networks Still Offer Free EU Roaming in 2026?

Picture this: you land in Faro, or Florence, or wherever your summer holiday has taken you, switch your phone off airplane mode, and… nothing. No welcome text confirming free roaming. Just silence, and a nagging worry that every WhatsApp photo you send home is quietly racking up a bill.

It's a fair worry to have. Since Brexit, "free roaming in Europe" stopped being something every UK phone contract simply included. Some networks kept it. Some brought back daily charges. Some split the difference with confusing "zones" and fair usage caps that nobody reads until it's too late. 📱

The good news is that the picture in 2026, while messy, isn't actually that hard to summarise once you strip away the jargon. A handful of networks — including one of the big four — still let you use your phone in Europe exactly as you would at home, with no daily fee at all. This guide walks through exactly who they are, what the small print actually says, and how to check your own contract before you fly.

The Quick Answer: Who Still Offers Free EU Roaming?

If you're short on time, here's the headline picture for 2026.

Still free, no daily charge:

  • O2 — the only one of the traditional "big four" networks that hasn't reintroduced roaming charges
  • giffgaff (runs on O2's network)
  • SMARTY (runs on Three's network)
  • iD Mobile, Asda Mobile, Lycamobile, Lebara, 1pMobile, spusu and a handful of other budget SIM providers

Charging a daily fee for most customers:

  • EE — around £2.47 a day
  • Vodafone — around £2.75 a day for standard plans (though some destinations and premium plans are still included)
  • Three — around £2.75 a day from April 2026, unless you're on specific plans
  • VOXI and Sky Mobile — both charge for roaming passes

That's the short version. Now let's get into why it's this way, and the details that actually matter when you're packing your case.

Why UK Roaming Changed After Brexit

It's worth a quick recap, because it explains why some networks kept free roaming and others didn't.

The End of "Roam Like at Home"

Between 2017 and the end of 2020, EU rules meant that anyone with a UK contract could use their phone anywhere in the EU exactly as they would at home — same allowance, same price, no exceptions. This was known as "Roam Like at Home," and it was a legal requirement, not something networks chose to offer.

When the UK left the EU, that requirement disappeared. From 1 January 2021, every UK network was free to make its own call: keep roaming free, charge for it, or land somewhere in between. Most kept it free for a while, simply because customers expected it. Then, gradually and mostly through the small print at contract renewal rather than any big announcement, EE, Vodafone and Three began charging daily fees for new and upgrading customers.

Why Some Networks Never Brought Charges Back

O2 took a different approach and stuck with it, branding it "Roam Like at Home." That decision has stuck for five years now, and O2 has picked up industry awards for it every year running.

The budget networks that still offer free roaming — giffgaff and SMARTY in particular — are able to do this partly because the wholesale cost of EU data has actually been falling. As of 2026, the EU caps what a UK network can be charged by European operators at roughly 95p per GB, dropping further in 2027. That cap, plus fairly modest fair usage limits, is what makes free inclusive roaming financially viable for these smaller providers.

The Big Four: Who Still Includes Roaming, and Who Charges?

O2 — Free Roaming, No Catch

O2 remains the standout. On any Pay Monthly or Pay As You Go plan, your UK data, calls and texts work exactly as they would at home across 48 European destinations, automatically, with no bolt-on to activate and no daily fee.

The only cap to know about: if your UK data allowance is more than 25GB a month, you're capped at 25GB while roaming (you'll get a text warning as you approach it). If your UK allowance is 25GB or less, your normal allowance applies abroad with no separate limit. There's also a fair usage rule — if you spend 63 days or more in the EU within a four-month period without clear evidence of UK use, O2 may eventually apply charges.

One genuine gotcha: Turkey and Morocco are not included in O2's Europe Zone, despite being popular holiday spots. Switzerland, Norway, and Iceland are included, which is handy if a European trip has you crossing borders.

EE — Daily Charges for Most Customers

EE was actually one of the first networks to bring roaming charges back. If you joined or upgraded on or after 7 July 2021, you'll pay around £2.47 a day to use your UK allowance across EE's 47 European destinations, with a 50GB fair usage cap once you're paying. If you're on a genuinely old, un-upgraded legacy contract from before that date, you may still have free roaming — it's worth checking the My EE app rather than assuming either way.

Vodafone — It Depends Which Zone You're In

Vodafone splits its roaming into zones, which trips a lot of people up. Zone A — the Republic of Ireland, Isle of Man, Iceland and Norway — is free on every Pay Monthly plan. Zone B, which covers most of the rest of the EU, carries a roughly £2.75 daily charge for anyone who joined or upgraded on or after 11 August 2021, unless you're on one of Vodafone's premium "Euro Roam" or "Global Roam" plans, which include it as standard. (More on Vodafone's full zone structure, and the other three networks' add-ons, in the next section.)

Three — Charges Are Increasing From April 2026

Three's position has shifted the most in the last year. From 1 April 2026, the standard daily charge for its "Go Roam in Europe" zone (49 destinations) rises to £2.75 a day. There are two groups who avoid this: customers who joined before 1 October 2021 and haven't upgraded since, and anyone currently on a Value or Complete plan, both of which still include free European roaming. Everyone else pays the daily rate, subject to a 12GB fair usage cap. The Republic of Ireland and Isle of Man are always excluded from the daily charge, regardless of plan.

Roaming Plans and Add-Ons: A Closer Look at the Big Four

If you're on EE, Vodafone, O2 or Three and roaming isn't included free on your specific plan, you're not stuck paying an open-ended per-megabyte rate. Every network sells some form of "roaming add-on" (sometimes called a bolt-on, pass, or travel pack) that unlocks your normal UK allowance abroad for a set fee. To understand how these work, it helps to understand roaming zones first — the geographical groupings each network uses to decide what you pay where. "Europe" on a roaming map is rarely just the EU; it usually includes a scattering of EEA countries and excludes a few surprising ones, so the zone your destination sits in matters more than its actual geography. 📶

EE: The Roam Abroad Pass and the Europe Zone

EE splits the world into its Europe Zone (47 destinations, covering all 27 EU states plus a handful of others like Switzerland and Norway) and Zone 1 (worldwide destinations including the USA, Canada, Australia and New Zealand), each priced separately.

  • Free roaming built in: EE's All Rounder and Full Works plans include EU roaming with no extra charge — Full Works extends this to worldwide roaming too. Genuinely legacy customers from before 7 July 2021 who haven't upgraded since are also still covered.
  • Roam Abroad Pass / EU Travel Pass: around £2.47 a day for everyone else, unlocking your normal UK minutes, texts and data (subject to a 50GB fair usage cap) in the Europe Zone for 24 hours.
  • Pay As You Go: a daily data add-on from around £2.50, or a weekly add-on around £10 for longer trips.
  • Beyond Europe: the separate Roam Further pass covers the USA, Canada, Mexico, Australia and New Zealand for around £5.91 a day — Europe and Zone 1 passes can't usually be combined, so multi-continent trips need planning.

Vodafone: Zones A–D and the Euro Roam Add-On

Vodafone's zone system is the most layered of the four, split into Zones A, B, C and D:

  • Zone A (Republic of Ireland, Isle of Man, Iceland, Norway) — always free, on every plan, no add-on needed.
  • Zone B (around 47–52 destinations, covering most of the EU) — included free on Vodafone's EVO plans with "Euro Roam" or "Global Roam" benefits, and on legacy contracts from before 11 August 2021. Everyone else pays roughly £2.75 a day, with a 25GB fair usage cap. For longer trips, Vodafone also sells set-length European roaming passes (typically an 8-day and a 15-day option) that work out cheaper than paying the daily rate for the whole holiday.
  • Zones C and D (rest of the world) — charged separately at somewhere between £6 and £8 a day depending on your plan and join date, on top of anything you're paying for Zone B.

One to watch: Vodafone and Three UK have merged into a single business, "VodafoneThree," during 2026. Nothing has changed for roaming customers yet, but it's worth keeping an eye on updates from either network in case their roaming structures start to align.

O2: Inclusive Zones Rather Than Paid Add-Ons

True to form, O2's approach for going beyond Europe still avoids a straight per-day roaming charge for a lot of customers, though it does use add-ons for everyone else:

  • Europe Zone — free on every plan, as covered above (48 destinations, 25GB cap).
  • Travel Inclusive Zone — free for Volt and Plus plan customers, covering 27 destinations outside Europe including the USA, Canada and Australia, with data capped at 2Mbps.
  • Travel Inclusive Zone Ultimate — free for Ultimate plan customers, extending that to 75 destinations, including Turkey, the UAE and Thailand.
  • O2 Travel Bolt On — for everyone else on Pay Monthly, this unlocks your UK allowance in 60+ destinations outside Europe for around £7 a day (also 2Mbps-capped). It isn't available on Pay As You Go.
  • Data Roaming Bolt Ons — standalone data top-ups (calls and texts aren't included) for anyone who just wants a set amount of data for a trip rather than a daily pass.

Three: Go Roam Tiers, Passes and the Data Passport

Three's Go Roam service is split into three tiers, each with its own price if it's not already included in your plan:

  • Go Roam in Europe — 49 destinations. Free on current Value and Complete plans (taken out from 22 June 2025) and on Pay As You Go; otherwise £2.75 a day from 1 April 2026.
  • Go Roam Around the World — a further 22 destinations including the USA and Australia. Free on Complete plans; otherwise £8 a day.
  • Go Roam Around the World Extra — another 92 destinations. Free only on Complete plans; otherwise £8 a day.

All three tiers share the same 12GB monthly fair usage cap, and the Republic of Ireland and Isle of Man are always excluded from any daily charge. If day-by-day charging doesn't suit a longer trip, Three also sells 3-day, 7-day and 14-day Go Roam passes as a fixed-cost alternative — worth pricing up against the daily rate in the Three app before you commit either way. For anyone who blows through the 12GB fair usage cap, the Data Passport add-on (around £7 a day) gives genuinely unlimited data for 24 hours across 89 destinations, removing the cap entirely for that day.

Budget Networks (MVNOs) With Free EU Roaming

If you're not tied to one of the big four, several of the UK's smaller SIM-only providers are actually the most generous option going in 2026 — and often the cheapest monthly plans too.

giffgaff — Free, With a 5GB Cap

giffgaff runs on O2's network and includes free EU roaming on every single plan, with no add-on required. The catch is a fairly tight data cap: a maximum of 5GB of your plan's data can be used while roaming in the EU, regardless of how much data your plan includes overall. Calls and texts are unlimited. Roaming is available for up to 63 days, provided you've used your SIM in the UK in the 63 days beforehand.

SMARTY — Free, With a More Generous 12GB Cap

SMARTY, which runs on Three's network, offers the same free roaming on all its rolling SIM-only plans, but with a noticeably better 12GB monthly data cap — more than double giffgaff's. For anyone doing a lot of Google Maps navigation, photo uploads or video calls home, that extra headroom makes a real difference.

Other Budget Networks Worth Knowing

A number of smaller providers also currently include free EU roaming, with fair usage limits that vary: iD Mobile, Asda Mobile, Lycamobile, Lebara, 1pMobile, and spusu among them. iD Mobile in particular tends to offer one of the largest fair usage caps around, which suits heavier data users.

One to watch: Tesco Mobile has historically included free EU roaming, but has signalled plans to phase this out for new and renewing customers during 2026. If you're a Tesco Mobile customer, it's worth double-checking your specific contract's terms directly before you travel, rather than assuming the old benefit still applies.

Which Countries Actually Count as "EU Roaming"?

This is where a lot of people get caught out, because "Europe" on your network's map doesn't always match the EU on an actual map.

  • Switzerland and Turkey are the two most common surprise exclusions — both feel like obvious "Europe" destinations, but neither is in most networks' free roaming zones, O2 included in Turkey's case.
  • Microstates like Andorra, Monaco and San Marino are sometimes excluded or treated separately, so check before a road trip that crosses borders.
  • Norway, Iceland and Liechtenstein, while not EU members, are usually bundled into UK networks' free zones because they're part of the wider European Economic Area. If Oslo or the fjords are on your list this year, our Norsk Folkemuseum review and Oslo Fashion Outlet review are worth a browse while you're planning.
  • Western Balkan countries — Montenegro, Albania, Serbia, Bosnia and Herzegovina, Kosovo and North Macedonia — are not part of any UK network's inclusive EU zone, even though the EU itself is in talks to bring some of them into its own free-roaming area by the end of 2026.

Watch Out for These EU Roaming Traps

Even on a network that advertises "free" roaming, a few things can still catch you out. ⚠️

Fair usage caps. "Free" rarely means unlimited. Caps range from 5GB (giffgaff) up to 25GB (O2, Vodafone), and once you're over the limit, you'll either be throttled or charged per gigabyte.

The 60-to-63-day rule. Every network has some version of a rule that flags your SIM if you spend too long roaming relative to time spent in the UK, usually somewhere around 60–63 days within a rolling four-month window. This is designed to stop people using a UK SIM as a permanent EU connection, not to catch out a normal two-week holiday, but it's worth knowing if you split your time between the UK and a second home abroad.

Inadvertent roaming. Near land borders, your phone can occasionally latch onto a network from a neighbouring, non-included country without you noticing — sometimes called "network drift." A text alert usually flags this, so it's worth reading roaming welcome texts rather than dismissing them.

Cruises. Roaming on a cruise ship is a different beast entirely, usually billed at maritime satellite rates that have nothing to do with your normal EU allowance. Switch data roaming off and rely on the ship's wifi unless you've specifically checked otherwise.

So, Which Network Should You Actually Choose?

It genuinely depends on how you travel:

  • Occasional European trips, want zero hassle: O2 or giffgaff. You don't need to remember to buy anything or activate anything — it just works.
  • Heavy data user (lots of maps, video calls, social media): SMARTY's 12GB cap or O2's 25GB cap will serve you better than giffgaff's 5GB.
  • Already with EE, Vodafone or Three and don't want to switch: budget the daily fee into your trip, or look at a short-term SIM-only deal from a free-roaming budget network just for the duration of your holiday — there's usually no long contract involved.
  • Splitting time between the UK and abroad: pay close attention to the 60-to-63-day fair use rules above, since this is the group most likely to be affected by them.

If you're weighing up whether a European trip is worth it against a UK break this year at all, our piece on the real cost comparison between a UK holiday and a holiday abroad in 2026 covers a lot of the same "hidden cost" territory as roaming charges do.

How to Check Your Own Roaming Allowance Before You Fly

A few minutes of checking now saves any nasty surprises later:

  1. Open your network's app (My O2, My EE, My Vodafone, My Three, or giffgaff/SMARTY's equivalent) and search "roaming" in your plan details.
  2. Check your specific destination is included. Don't assume — Switzerland and Turkey catch people out every year.
  3. Text your network if you're unsure. Most have a simple text-to-check service (EE, for example, uses "ROAM" to 150).
  4. Set a spend cap. Ofcom requires every UK network to let you set a roaming spend cap — a sensible safety net even on a network you trust.
  5. Turn off data roaming manually if you're on a network that charges, and rely on wifi where you can, switching it on only when you need it.

Final Thoughts

Five years on from Brexit, free EU roaming hasn't disappeared in the UK — it's just narrowed down to a smaller, more specific list of networks. O2 remains the only big-name provider that hasn't reintroduced charges, and giffgaff and SMARTY quietly offer some of the best value going if you're happy with a SIM-only plan. Everyone else can still roam comfortably in Europe; it's simply a case of knowing the daily rate, the fair usage cap, and which countries are actually included before you go.
