The Short Answer
Fuse Mobile's Pulse and Surge plans include roaming in 130+ countries at no extra cost — your normal monthly data allowance works abroad, with no daily fees and no surprise bills. But before you pick any plan, it's worth understanding what "no roaming charges" actually means in practice, because not every provider uses the term the same way.
What Does "No Roaming Charges" Actually Mean?
It sounds simple. You travel, your phone works, nothing extra appears on your bill. In reality, "no roaming charges" is one of the most misused phrases in the mobile industry. Providers use it to mean very different things, and the difference can cost you real money.
There are broadly three models you'll encounter when shopping for a UK SIM with roaming included.
Model 1: Daily Roaming Passes
Some providers charge a flat daily fee — often somewhere between £1 and £6 per day — to activate roaming on a given day. They'll market this as "no surprise charges" because the fee is predictable. But it's still a charge. A two-week holiday can quietly add £14–£84 to your bill before you've used a single megabyte. If you travel frequently, those daily fees compound fast.
The key question to ask: Is there any daily activation fee, even a small one?
Model 2: Restricted-Allowance Roaming
This model is subtler. Roaming is technically "included" — no daily fee — but your full UK data allowance isn't available abroad. You might have 30GB at home but only 5GB or 10GB usable in Europe, and potentially nothing outside the EU. Some plans cap roaming speeds as well, throttling you to 3G even if 5G is available locally.
The key question to ask: Does roaming use my full UK allowance, or a reduced version of it?
Model 3: Genuinely Included Roaming
The cleanest model: your normal monthly allowance travels with you. You use the same data pot whether you're in London, Los Angeles, or Lisbon. No daily fees, no separate roaming bucket, no reduced allowance. Coverage extends well beyond the EU — ideally to the USA, Asia, and further.
This is what Fuse's Pulse and Surge plans offer. Your 10GB (Pulse) or 15GB (Surge) monthly allowance works in 130+ countries exactly as it does at home. You can see the full country list at fuse.co.uk/roaming.
The Questions to Ask Before You Travel
When you're evaluating any UK SIM for roaming, run through these four questions. They'll cut through the marketing quickly.
1. Does roaming use my full UK allowance?
If the answer is no — if there's a separate, smaller roaming allowance — you're effectively on a restricted plan abroad. That's not the same as genuinely included roaming.
2. Is there a daily activation fee?
Even a modest daily fee changes the economics of travel significantly. A week in New York at £2/day is £14. A month-long trip is £60. Ask explicitly: is there any charge triggered by using data abroad?
3. How many countries are covered?
EU-only roaming is common and useful, but it leaves you unprotected everywhere else. The USA, Canada, Japan, Australia, Thailand, the UAE — these are all popular UK travel destinations that fall outside EU coverage. Look for a plan that covers the places you actually go, not just the places a regulation requires.
Fuse covers 130+ countries across Europe, the Americas, Asia-Pacific, the Middle East, and Africa. Check the full roaming country list before you book.
4. What happens if you go over your allowance abroad?
Some providers charge per-MB overage rates that can be eye-watering. Others simply stop your data when you hit your limit. Know which model applies before you travel — running out of data is manageable; an unexpected overage bill is not.

Why UK Coverage Matters Just as Much
It's easy to focus entirely on roaming when you're planning a trip, but a plan with great international coverage and poor UK signal is a poor trade-off. You live here. Your day-to-day connectivity matters more than your two weeks in Bali.
This is where the network question becomes important. Most UK SIMs run on a single network — whichever operator owns or hosts that MVNO. If that network has a gap in your area, you're stuck with it.
Fuse works differently. It's an eSIM that connects to all four UK networks — EE, Three, Vodafone, and O2 — and automatically switches to whichever has the strongest signal wherever you are. That means fewer dead zones at home, better coverage on rural roads, and more reliable signal in buildings. You can read more about how Fuse's coverage works.
Fuse is the only UK provider that combines genuine all-four-network multi-network coverage with roaming in 130+ countries. The home-side and the abroad-side of the equation are both covered.
EU Roaming vs. Global Roaming: Know the Difference
Since the UK left the EU, providers are no longer legally required to offer free EU roaming. Many still do — it's a competitive necessity — but the quality and extent of that coverage varies.
More importantly, EU roaming and global roaming are very different things. EU coverage typically means the 27 EU member states plus a handful of EEA countries (Norway, Iceland, Liechtenstein). It doesn't include the USA, Canada, Mexico, the UAE, India, Japan, South Korea, Singapore, Australia, or most of Africa and Latin America.
If you travel beyond Europe — for business, for holidays, to visit family — EU-only roaming isn't enough. You need a plan that explicitly covers the regions you visit.
When you're comparing plans, look at the actual country list, not just the headline claim. "Roaming included" with 30 countries is a very different product from "roaming included" with 130+.
What Fuse's Roaming Plans Actually Include
Fuse has three plans. It's worth being clear about what each one covers:
- Spark — 5GB, £5.99/month. UK only. No roaming.
- Pulse — 10GB, £9.99/month. Roaming included in 130+ countries. Uses your UK allowance abroad. No daily fees.
- Surge — 15GB, £14.99/month. Roaming included in 130+ countries. Uses your UK allowance abroad. No daily fees.
Pulse and Surge are rolling monthly plans — no contract, cancel anytime. Activation is instant via QR code, so you can be set up before you leave the house.
If you want to try Fuse before committing, there's a 7-day free trial with 500MB included. It converts to your chosen plan at the end of the trial period.

The Aggregator Gap: Why Comparison Sites Don't Tell the Full Story
Price comparison sites are useful for spotting the cheapest headline price, but they're poorly suited to explaining how a roaming model works. They'll list whether roaming is "included" or not, but they won't tell you whether that means your full allowance travels with you, whether there's a daily fee buried in the small print, or how many countries are actually covered.
That's the gap worth closing before you travel. The difference between a plan that charges £2/day in the USA and one that includes the USA in your normal allowance is meaningful — especially if you travel more than a few times a year.
The questions in this article are the ones worth asking of any provider, not just Fuse. If a plan's roaming terms aren't clear from the main plan page, that's usually a sign the terms aren't in your favour.
FAQ
Does Fuse charge a daily fee to use roaming?
No. On Pulse and Surge plans, roaming in 130+ countries is included in your monthly plan. There are no daily activation fees and no per-day roaming passes. You simply use your normal monthly data allowance abroad.
Which Fuse plans include roaming?
Pulse (10GB, £9.99/month) and Surge (15GB, £14.99/month) both include roaming in 130+ countries. Spark (5GB, £5.99/month) is a UK-only plan and does not include roaming.
Does my full UK data allowance work abroad, or is there a reduced roaming allowance?
Your full monthly allowance is available abroad on Pulse and Surge. There's no separate, smaller roaming bucket — the same 10GB or 15GB works whether you're in the UK or overseas.
Which countries does Fuse roaming cover?
Fuse roaming covers 130+ countries across Europe, North America, Asia-Pacific, the Middle East, Latin America, and Africa. The full country list is available at fuse.co.uk/roaming.
What makes Fuse different from other UK SIMs for roaming?
Fuse combines two things no other UK provider currently offers together: roaming in 130+ countries on Pulse and Surge plans, and all-four-network UK coverage (EE, Three, Vodafone, and O2) with automatic signal switching. Most providers offer one or the other — Fuse offers both.
Summary
"No roaming charges" means different things from different providers. The three questions that matter most are: does your full UK allowance work abroad, is there any daily fee, and how many countries are actually covered? Fuse's Pulse and Surge plans answer all three cleanly — included roaming in 130+ countries, no daily fees, using your normal monthly data. Pair that with all-four-network UK coverage, and you've got a plan that works as well at home as it does abroad.
