The best eSIM for the UK in 2026. Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for the UK, priced on the same day: two weeks unlimited for $12.99, cheapest month and bucket.
Prices read on 26 September 2026. Six travel eSIMs sell a United Kingdom plan and get most of the traffic for this search. We priced all six on the same day, for a city break in London and for a month across the country, and read the fine print on unlimited. Here is where each one wins.
Ringo Light: Cheapest unlimited for two weeks or a month. Unlimited data at full speed for 2 weeks at $12.99 or 30 days at $21.99, one payment each, nothing renews. Airalo, Holafly and Saily ask $27 to $29 for one week.
Ubigi: Cheapest bucket, and the most full speed data in a month. 10 GB for 30 days at $11 on EE and Three, and unlimited for 30 days at $44 with 60 GB at full speed, then 2 Mbps.
Nomad: Cheapest 20 GB. 20 GB for 30 days at $25 to $26, and a 50 GB bucket at $39 for people who work from the hotel.
Holafly: Simplest unlimited. Days, not gigabytes, no daily cap stated for your own phone, and it lists five UK networks. $27.50 for a week; sharing limited to 1 GB a day.

For a week or two, the gap is wide. Airalo, Holafly and Saily charge $27 to $29 for 7 days of unlimited data in the UK. Nomad charges $25 and Ubigi $21. Ringo Light charges $12.99 for 2 weeks, one payment. It no longer sells 3 days: for a long weekend, Nomad at $11 is the cheapest 3-day plan here.
For a month, Ringo Light is the cheapest at $21.99, half of Ubigi at $44. The difference is how much runs at full speed. Our 30 days starts with 20 GB, and when you have used 80% we add 10 GB once and charge the $12.99 top-up, so a heavy month costs $34.98. Ubigi states 60 GB at full speed for $44, then 2 Mbps, which is more full speed data if you work from the hotel. Airalo, Saily and Holafly cost $69 to $73.90 for the same 30 days.
Read what unlimited means before you pick. 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 has no speed cap: the 2 weeks starts with 10 GB and the 30 days with 20 GB, each adding 10 GB once at 80%, charged.
Ubigi, $11 for 10 GB. The cheapest 10 GB by a distance, on EE and Three with 5G, and 25 GB for $22. The app is needed for top-ups.
Nomad, $17.50 for 10 GB. Its price moves with sales, $17.50 to $19 the day we looked, and 20 GB at $25 to $26 is the cheapest 20 GB here. 50 GB is $39.
Ringo Light, no buckets. Our 2 weeks starts with 10 GB for $12.99, and our 30 days with 20 GB for $21.99. For 10 GB that lasts a whole month, Ubigi at $11 is cheaper and lasts longer. Buy ours 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.

You need your own number to keep ringing. None of these travel plans does that. The full Ringo, which Ringo Light funds, ports the number you have.
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.
Big Ben and the Houses of Parliament, Westminster, London. The clock tower and the Gothic palace on the Thames, best seen from Westminster Bridge or the South Bank. Come at dusk when the tower lights up. Tap your phone or contactless card at the Tube gates; the daily fare caps itself, no ticket needed.
Tower Bridge and the Tower of London, London. The Norman fortress that holds the Crown Jewels sits right beside the bascule bridge from 1894. Walk the bridge after the Tower and cross to the south bank. Book Tower tickets on your phone before you go and show the QR code at the gate.
Edinburgh Castle and the Royal Mile, Edinburgh. The castle crowns a volcanic rock at the top of the Royal Mile, which runs down through the Old Town to Holyrood. August brings the Fringe and a much fuller city. Buy the train from London on a rail app and keep the e-ticket on your phone; it is about four and a half hours.
Glencoe, Scottish Highlands. A deep glen under the Three Sisters ridges on the A82, the road north to Fort William and Skye. The walks start from the roadside car parks. Signal drops in the glens. Download offline maps before you leave Glasgow or Fort William.
The Roman Baths, Bath. A Roman bath complex still fed by hot springs, next to Bath Abbey in a city of Georgian stone terraces. About ninety minutes by train from London Paddington. Timed entry slots sell out in summer; book on your phone the day before.
Stonehenge, Wiltshire. The prehistoric stone circle on Salisbury Plain, reached by a shuttle from the visitor centre. Most visitors combine it with Bath or Salisbury in one day. Buses from Salisbury station are few; check the live times in a transit app before you ride out.
Derwentwater, Keswick, Lake District. A lake ringed by fells beside the market town of Keswick, with a launch that calls at jetties around the shore. Friars Crag is a short walk from town. Weather on the fells turns fast. Check the mountain forecast on your phone before any climb.
Bibury and the Cotswolds, Gloucestershire. Honey stone villages in rolling hills west of Oxford, with Arlington Row in Bibury the most photographed street. Easiest by car, or by train to Moreton-in-Marsh or Kemble. Village buses run rarely. Book a taxi or car in an app ahead, as few wait at rural stations.
We priced Airalo, Holafly, Saily, Nomad, Ubigi and Ringo Light for United Kingdom on 26 September 2026, all on the same day, in US dollars. Each rival's price comes from its own website where it showed dollars, otherwise from an esimdb.com listing, and every source and its date is listed below. Ringo Light's prices come from the catalogue our checkout charges.
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.
