The short answer
Six travel eSIMs sell a United Kingdom plan and get most of the traffic for this search. I priced all six on the same day, for a city break in London and for a month across the country, and I read the fine print on unlimited. Here is where each one wins.
Unlimited data at full speed for 2 weeks at $14.99 or 30 days at $26.99, and nothing renews. I found Airalo, Holafly and Saily at $26.99 to $27.50 for one week.
10 GB for 30 days at $11 on EE and Three. Its unlimited for 30 days is $44, with 60 GB at full speed, then 2 Mbps.
20 GB for 30 days at $25 to $26. I would look at its 50 GB bucket at $39 if you work from the hotel.
It sells days, not gigabytes, states no daily cap for your own phone, and lists five UK networks. I read $27.50 for a week, with sharing limited to 1 GB a day.
Prices read on 10 November 2026: Airalo, Holafly, Saily, Nomad, Ubigi on their own sites or listings, Ringo Light from its catalogue. All in US dollars unless stated. Treat every number as a snapshot.

We sell data eSIMs for now to fund the full Ringo service. Ringo is self funded. Every plan bought here pays for the build of one plan that works everywhere.
Want to keep your own number abroad?
That is the full Ringo service: one plan that works everywhere, with your own number included.
It is a separate product from Ringo Light and it is still being built, so it is not on sale yet. Join the waitlist to hear when it opens.
What to do in the UK, and what your phone needs for it
Eight places most first trips include, from London to the Scottish Highlands, with the one thing your data does for you at each. Coverage is strong in the cities and along the main roads, and thin in the glens and fells.
If you want unlimited: Ringo Light for two weeks or a month
For a week or two, the gap is wide. I read Airalo, Holafly and Saily at $26.99 to $27.50 for 7 days of unlimited data in the UK. Nomad charges $25 and Ubigi $21. Ringo Light charges $14.99 for 2 weeks. For a long weekend it sells 3 days at $8.99, against $11 at Nomad.
For a month, I count Ringo Light as the cheapest at $26.99, which is $17.01 under Ubigi at $44. The 30 days on Ringo Light is unlimited data at full speed. Ubigi states 60 GB at full speed for $44, then 2 Mbps. Airalo, Saily and Holafly cost $69 to $76.50 for the same 30 days.
Read what unlimited means before you pick. I did, brand by brand. Airalo gives 3 GB a day at full speed, then about 1 Mbps. Saily gives 5 GB a day, Nomad 2 GB. Holafly states no daily cap for your own phone and limits sharing to 1 GB a day. Ringo Light is unlimited data at full speed for 2 weeks or 30 days.
If you want a data bucket: Ubigi, then Nomad
- Ubigi, $11 for 10 GB. The cheapest 10 GB by a distance, on EE and Three with 5G, and 25 GB for $22. I would note that the app is needed for top-ups.
- Nomad, $17.50 for 10 GB. Its price moves with sales, $17.50 to $19 the day I looked, and 20 GB at $25 to $26 is the cheapest 20 GB here. 50 GB is $39.
- ✓Ringo Light, no buckets. Its 2 weeks is unlimited for $14.99, and its 30 days unlimited for $26.99. For 10 GB that lasts a whole month, Ubigi at $11 is cheaper and lasts longer. I would buy Ringo Light for unlimited, not as a bucket.
- Saily, $18.99 for 10 GB. Cleanest app of the six, 20 GB at $30.99. A full refund inside 30 days if you never install it.
- Airalo, $19 for 10 GB. The biggest name, on EE, buckets from $4 for 1 GB. A wrong purchase is refunded as Airmoney credit, not cash.
What Ringo Light is
Ringo Light is the data eSIM from the company I write for, sold to fund the full Ringo, one plan that works everywhere with your own number ported onto it. For the United Kingdom it sells three trips, all unlimited data at full speed: 3 days at $8.99, 2 weeks at $14.99 and 30 days at $26.99. Nothing renews. The eSIM arrives by email in seconds and installs in one scan, no app.
The card to buy it is further up this page, just after the side-by-side table. I would read the table first.
Pick by trip
I would buy Ringo Light unlimited, 3 days, $8.99, against $11 at Nomad. Its 2 weeks is $14.99 if the trip might run longer.
I would buy Ringo Light unlimited, 2 weeks, $14.99, less than any rival charges for one week. I would pick Holafly at $27.50 only if you want a stated no-cap plan and its five-network list.
My pick is Ubigi 10 GB at $11.
I would buy Ringo Light unlimited, 30 days, $26.99, with no app to install. I would take Ubigi at $44 if you want its stated 60 GB at full speed.
None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.

We compare the trips people actually book: a week, two weeks and a month of unlimited data, and a 10 GB bucket. We read each brand's fair use and speed rules and quote them as the brands state them. We did not run speed tests, so this page makes no speed claims for any brand.
Ringo Light is our own product. We put it in the table on the same terms as everyone else, and where a rival is the better buy the page says so.
Left out: Maya Mobile. We could not read its own prices for this country on the day, so it stays out rather than being guessed.
