Why UK Travellers Are Switching to eSIM (And You Should Too)
If you've taken a holiday abroad recently, you'll know the dread of turning off aeroplane mode and watching your data roaming charges tick up. For UK travellers, this pain got significantly worse after Brexit — and it's pushing a growing number of Brits to discover eSIM.
Here's what's changing, why people are making the switch, and what it means for your next trip.
The Roaming Problem Got Worse After Brexit
Until January 2021, UK travellers could roam across all 27 EU countries at no extra cost — the same data allowance, the same price. That protection ended with Brexit, and UK mobile operators are no longer required to offer free EU roaming.
Today, most UK networks charge daily roaming add-ons for European travel:
- EE: £2/day for use-your-allowance roaming (limited to certain plans)
- Vodafone: £1/day on some plans, roaming entirely removed from others
- O2: £3.99/day Roam Boost
- Three: Still offers some free EU roaming, but policies are evolving
For long-haul travel — USA, Asia, the Middle East — UK roaming prices have always been eye-watering, often £5–£10 per day or more.
What Is eSIM and Why Does It Fix This?
An eSIM is a digital SIM card built into your phone. Instead of relying on your UK carrier's expensive roaming rates, you simply buy a local data plan from a company like Ukesim.io, receive a QR code, and scan it. Your phone connects to a local network at local prices.
The result? You might pay £8–15 for a full week of data in Europe or the USA, compared to £14–70 with UK carrier roaming.
Five Reasons UK Travellers Are Making the Switch
1. It's Dramatically Cheaper
The price difference is often staggering. A week of European data on an eSIM plan typically costs less than two days of roaming with a UK carrier. For families or frequent travellers, the savings add up to hundreds of pounds a year.
2. It's Instant
No waiting for a physical SIM to arrive in the post. No hunting for a SIM card shop after a long flight. You buy your eSIM before you travel, scan the QR code, and you're connected the moment you step off the plane.
3. You Keep Your UK Number
eSIM lets you run two connections simultaneously — your UK SIM for calls and texts, your eSIM for data. Friends and family can still reach you on your normal number. No need to hand out a temporary local number.
4. No More Plastic Waste
Every year, billions of plastic SIM cards are produced and discarded. An eSIM is entirely digital — better for the environment and one less thing to lose or damage.
5. It Works With Your Existing Phone
If you own an iPhone XS or later, a Samsung Galaxy S20 or later, or most Android flagships from 2019 onwards, you almost certainly already have eSIM capability built in. You don't need a new phone — just a different way of thinking about connectivity.
Who Is eSIM Best For?
eSIM is a particularly good fit if you:
- Travel abroad more than twice a year
- Hate the hassle of buying local SIM cards on arrival
- Want to avoid bill shock when you get home
- Travel with family (each person gets their own plan, sized for their needs)
- Work remotely or travel long-term and need reliable, flexible data
How to Get Started
- Check your phone is eSIM-compatible (most phones from 2019+ are)
- Make sure your phone is network-unlocked (contact your carrier if unsure)
- Visit Ukesim.io and browse plans for your destination
- Buy a plan — you'll receive a QR code instantly
- Scan the QR code in your phone's Settings
- Activate when you land
It really is that simple. The days of hunting for SIM card shops in foreign airports, or coming home to a £200 roaming bill, are over.
The UK Is Leading eSIM Adoption in Europe
The UK is one of the fastest-growing eSIM markets in Europe, partly driven by Brexit roaming changes and partly because Brits are among the world's most enthusiastic international travellers. Demand for eSIM in the UK has surged, and the range of available plans and providers has grown with it.
Ukesim.io was built specifically for this market — UK travellers who want a straightforward, transparent way to get connected abroad without the faff. Browse our plans and see why thousands of UK travellers have already made the switch.
