Everyone Budgets for the Flights. Almost Nobody Budgets for the Data.
You plan the trip properly. Flights compared across three tabs, hotel picked after reading the reviews that mention the shower pressure, a rough daily spend worked out for food and taxis.
Then you land, your phone reconnects, and you spend the first ten minutes of the holiday standing near baggage reclaim trying to work out whether your plan covers this country or whether you have just started paying by the megabyte.
It is the one line of the travel budget almost nobody works out in advance, and it has quietly become one of the more important ones. Not because the charges are catastrophic, but because the thing you are paying for has changed. Data abroad is no longer a nice extra for posting photos. It is the map, the boarding pass, the restaurant booking, the translation app, the taxi you cannot hail any other way, and the only proof you have that you paid for the museum ticket.
“We’ll just use the hotel Wi-Fi” stopped being a plan years ago
There is a specific kind of holiday friction that comes from being offline in an unfamiliar city. You screenshot the walking directions before you leave the room. You get one street wrong. Now you are standing outside a pharmacy trying to reverse-engineer a route from an image taken at a different zoom level.
Meanwhile the practical stuff has moved onto phones and stayed there. Airlines nudge you toward the app. Restaurants want the QR code. Much of Europe’s public transport now assumes you can load a ticket on the spot. Museums release timed-entry slots that sell out while you are hunting for a café with Wi-Fi.
So the question is not really whether you need data abroad. It is which of the three ways of getting it is least annoying for the way you actually travel.
The three options, honestly compared
Roaming included in your plan. You land, your phone connects, nothing happens. No apps, no top-ups, no thinking. This is the best experience by a distance, and it depends entirely on whether your specific plan includes it. Plenty of people assume theirs does because an older contract did, which is where most of the unpleasant surprises come from.
A daily roaming charge or travel pass. Your network lets you use your normal allowance abroad for a set fee per day. Simple, predictable, and good value for a week away. Less good for a slow three-week trip, where the daily fee quietly adds up to more than the seat upgrade you talked yourself out of.
A local or regional eSIM. You buy data for the country you are visiting, usually cheaper per gigabyte than roaming. The trade-off is faff. You install it, you often lose your normal number for calls and texts, and you get to do it again for the next country. For long trips or heavy data use the maths can genuinely favour it. For a long weekend in Lisbon, you have spent twenty minutes to save the price of a coffee.
There is no universally correct answer here, only the one that matches your trip. Which is why the sensible first move is finding out what your current plan actually includes before you compare anything else.

Where Three fits into this
Three has built much of its consumer proposition around exactly this problem, and its roaming setup is unusually specific about where you are going rather than treating “abroad” as one undifferentiated category.
The service is called Go Roam, and it splits into three bands: 49 destinations in Europe, 22 more under Go Roam Around the World, and a further 92 under Around the World Extra. That is over 160 destinations in total, which covers most places a UK traveller is realistically flying to.
What you get depends on your plan. Three restructured its consumer plans under the Three Your Way banner, and roaming is one of the main things separating the tiers:
- Lite is the entry option. Unlimited calls and texts, 5G at no extra cost, Three+ rewards. Roaming is not included, so you pay per day or buy a pass.
- Value adds inclusive roaming across the 49 Go Roam in Europe destinations, plus extended warranty when taken with a device.
- Complete extends inclusive roaming to the full 160-plus destinations, and adds screen repair cover on 24-month contracts and Paramount+ for the contract duration.
Three Your Way also lets you spread device payments across 12, 24 or 36 months and move between plan tiers without clearing the device balance first, which is more flexible than the traditional lock-in.
Then there is the network question, which changed materially in June 2025 when Three and Vodafone completed their merger. Three continues as its own consumer brand, but it now sits inside VodafoneThree alongside Vodafone, VOXI, SMARTY and Talkmobile, with a stated £11bn network investment programme behind it. The company says Three and SMARTY customers saw up to a 20% average 4G speed boost within weeks of completion, that customers gain access to roam across both networks domestically, and that the combination closes around 16,500 square kilometres of coverage gaps. Its longer-term target is 99.95% 5G standalone population coverage by 2034.
That last set of numbers is worth reading in both directions. It is a real investment commitment, and it is also a fairly direct acknowledgement that standalone Three had coverage gaps worth 16,500 square kilometres. If your historic complaint about a network has been signal in rural areas rather than data allowance, that is the honest context.

The fine print that actually matters
There is a fair use cap on roaming data. Pay Monthly customers can use up to 12GB of their allowance in any Go Roam destination per month, even on unlimited plans. For a two-week holiday that is plenty. For a month of remote working from Spain, it is not.
Your daily rate depends on when you joined. Three’s support pages list different roaming charges by plan join date, and the rates for people joining after December 2025 are higher than for those who signed up in the years before. If you are on an older plan, do not assume a figure you read somewhere applies to you. If you are joining now, check the current rate rather than the one a friend quotes.
Older Advanced plans do not include roaming at all, and do not support the Around the World Extra band.
Ireland is treated separately and sits outside the 12GB cap, which is sensible design given how easily you can pick up an Irish signal without meaning to.
Prices and plan structures move. Everything above reflects what Three publishes at the time of writing, and it is worth confirming the current numbers on the plan you are actually considering rather than taking any article’s word for it, this one included.

Who this suits, and who should look elsewhere
Three makes obvious sense if you travel a few times a year to mainstream destinations, you want your phone to simply work when you land, and you would rather not be managing eSIM installations in an airport. Value for European travel and Complete for anything further afield is a clean split, and being able to move between tiers mid-contract is genuinely useful if your travel pattern changes.
It makes less sense in a few specific situations. If you are a heavy data user abroad, the 12GB roaming cap will find you before your allowance does. If you spend long stretches in one country, a local eSIM will almost certainly cost less. And if your priority is signal strength in rural Britain rather than data abroad, that is a coverage question first and a plan question second, worth checking against a coverage map for your actual postcode before anything else.
The five-minute version
Before your next trip, check three things. Whether your plan includes roaming or charges per day. Whether your destination sits in the band your plan covers, not just “abroad”. And whether the fair use cap matches how much data you actually get through in a fortnight.
If any of those three answers is unwelcome, you have found something worth fixing before you book rather than after you land. It is a small piece of admin that takes about as long as choosing a seat, and it is the difference between a holiday where the phone quietly does its job and one where it becomes a running problem you paid extra for.
