🇬🇧 Best eSIM for United Kingdom
We hold verified pricing from Saily, Airalo, Yesim and co:sim for United Kingdom, starting at $1.99.
There is no single best eSIM for United Kingdom, only the best one for how long you're staying and how much you'll actually use. A three-night city break and a three-week trip want completely different plans, and the cheapest per gigabyte is almost never the cheapest for a specific trip.

Which network you'll actually be on
In United Kingdom these plans roam on EE. That matters more than the brand on the app, coverage, indoor signal and 5G access are the host network's, not the reseller's.
Or cover the whole region
United Kingdom is included in regional Europe plans. If you're visiting more than one country, that's often cheaper than stacking a local plan in each, and always simpler.

Before you buy
- Unlimited has a speed limit. Airalo's unlimited plans are widely reported to throttle around 3GB/day; Holafly's carrier fair-use sits around 3–5GB.
- Hotspot is capped separately. Holafly limits tethering to 1GB/day even on unlimited plans. If you're working off a laptop, that's disqualifying.
- Validity is wall-clock. A 7-day plan dies on day 7 whether you used it or not. Match the window to your trip, not your appetite.
- No phone number. Almost all travel eSIMs are data-only, so SMS verification codes won't arrive.
