What Is the Best eSIM for the UK in 2026? 10 Providers Compared

Saily is a strong choice if you're landing at Heathrow or Gatwick and want internet ready for train tickets, directions, hotel check-in, and WhatsApp. You buy the package online, install the eSIM while you have Wi-Fi, and it connects in the UK once the travel profile and necessary roaming settings are enabled.

Saily UK data plans and pricing

• 1GB / 7 days — US$4.49.
• 3GB / 30 days — US$8.99.
• 5GB / 30 days — US$12.99.
• 10GB / 30 days — US$18.99.
• 20GB / 30 days — US$30.99.

Saily also lists an unlimited option. Check its selected duration and high-speed allowance at checkout rather than assuming every unlimited package gives unrestricted 5G speeds all day.

Saily coverage and features in the UK

Saily's UK product is designed for England, Scotland, Wales and Northern Ireland. As with every travel eSIM, the signal depends on the local partner network, your phone and the specific location. City coverage is usually simpler than a trip through remote valleys, mountains and islands.

Its app adds web-protection tools, an ad blocker and a virtual-location feature, which are useful extras when traveling. Saily says its hotspot access isn't separately restricted, although it still draws from the allowance on a fixed-data plan. It also advertises separate phone-number packages with optional calling or SMS, so don't assume a basic data purchase includes a UK number.

Our verdict on Saily

Saily is the easiest general recommendation for a visitor who wants a straightforward eSIM for a week or two. It isn't the absolute cheapest 10GB option, but its combination of convenience and additional app features makes it worth considering.

If price per gigabyte is your priority, Ubigi is one of the strongest alternatives in this comparison. Its UK 10GB package is substantially cheaper than several better-known travel eSIM brands on their current public product pages.

Ubigi UK pricing

• UK 10GB / 30 days — US$11.
• UK unlimited / 30 days — US$44 (fair-use policy applies).

The 10GB product is a one-time plan rather than a recurring subscription. Ubigi's Smartstart feature starts its validity when it first connects in the destination. You can top up the reusable eSIM profile from the app on future trips.

Which UK networks does Ubigi use?

Its published 10GB UK listing identifies EE and Three as local network partners. Both serve major towns and cities, but their coverage patterns differ. If you're visiting the Scottish Highlands or rural Wales, check Ofcom's postcode coverage map against the particular network partners before leaving.

Ubigi allows mobile hotspot sharing, which makes the fixed 10GB plan useful for occasional laptop use or getting another device online. Standard packages are data-only, so normal phone calls and SMS are not included.

Our verdict on Ubigi

Ubigi is our value pick for a ten-day or two-week UK vacation if you expect to use around 10GB. At US$11, that package is difficult to ignore. We'd choose it ahead of a more expensive product when its partner-network coverage suits the itinerary.

Nomad stands out in the UK because it offers both ordinary data-only packages and specific packages that include a voice and SMS allowance. That can be particularly helpful when you need to call accommodation, arrange a service appointment, or receive a conventional message.

Nomad UK plans and prices

• 1GB / 7 days — US$4.50.
• 3GB / 30 days — US$9.
• 5GB / 30 days — US$12.
• 10GB / 30 days — US$17.50.
• 20GB / 30 days — US$25.
• 5GB + 100 minutes + 100 SMS / 30 days — US$13.
• 10GB + 200 minutes + 200 SMS / 30 days — US$19.
• Unlimited / 7 days — US$25.

Nomad also advertises a 30-day 'Unlimited Full-Speed' product at US$49. That wording still requires reading the relevant package's fair-use conditions; don't interpret it as a guarantee of a particular speed or coverage everywhere.

Nomad networks and hotspot support

Nomad's UK data plans run on Three and EE, while its call-and-text plans use Vodafone. The exact networks available to you depend on which package you purchase. The company advertises hotspot support on relevant UK plans.

Standard unlimited daily packages may slow after their daily high-speed allotment and reset the next day. Read the displayed rules for the specific unlimited option rather than assuming all Nomad plans behave the same way.

Our verdict on Nomad

Nomad may be the most convenient option if you definitely need normal calling or texts during your UK holiday. For example, its US$19 package combines 10GB, 200 minutes and 200 texts over 30 days. If you only need internet, compare its US$17.50 data package with Ubigi's US$11 plan.

Airalo offers country-specific, European and broader international eSIM packages. If you are spending five days in London and then taking the Eurostar to Paris, the ability to compare those regional choices in one place is useful.

Airalo UK data-only plans

• 1GB / 3 days — US$4.
• 3GB / 7 days — US$9.
• 5GB / 7 days — US$12.
• 10GB / 7 days — US$18.
• 10GB / 30 days — US$19.
• 20GB / 30 days — US$31.
• 50GB / 30 days — US$39.

Its UK plan page identifies EE as a primary network for the displayed package. If you're visiting less populated areas, verify that network's local coverage before booking.

Does Airalo have UK plans with calls and SMS?

Yes. Selected Airalo UK packages explicitly include data, minutes and SMS. One published example is 10GB + 100 minutes + 100 texts for 7 days at US$21.50, or 10GB + 100 minutes + 100 texts for 30 days at US$23.50. Those are distinct from the standard data-only plans.

Remember that a country-only UK eSIM won't necessarily cover the Republic of Ireland or your onward trip to mainland Europe. The UK and EU/Europe regional package options have their own country lists and prices.

Our verdict on Airalo

Airalo is a good option for travelers who want one platform to compare UK-only, UK-and-Europe and global choices. If you're staying only in London, its 10GB package isn't our cheapest pick; for a multi-country itinerary, the wider catalog is the advantage.

Holafly's main pitch is simple: choose your trip length and use mobile data without counting down from a fixed 5GB or 10GB balance. It can be convenient when you're using maps, Instagram, messaging, and video throughout the day.

Holafly UK unlimited prices

• 3 days — US$11.90.
• 5 days — US$20.50.
• 7 days — US$27.50.
• 10 days — US$37.50.
• 15 days — US$51.50.
• 30 days — US$76.50.

These are the published USD prices listed on Holafly's UK page; the site's shopping selector may display another currency. Choose an exact duration and review the final checkout price.

The unlimited and hotspot conditions

Holafly's unlimited mobile data remains subject to its fair-use policy and partner-network speed management. A drop in speed may happen in periods of high consumption. On its UK plan, hotspot sharing is limited to 1GB per day, even though phone data itself is marketed as unlimited.

That's an important difference for remote workers. You could browse on your phone throughout the day but hit the separate hotspot limit while connecting a laptop. Holafly also advertises an Always On backup-data benefit; check eligibility and the countries covered.

Where does Holafly work in the UK?

Its UK plan is intended for England, Scotland, Wales and Northern Ireland. Holafly specifically warns about weaker or inconsistent connectivity in rural and mountainous areas such as parts of the Scottish Highlands, Isle of Skye, Snowdonia/Eryri and the Lake District. Those are network coverage limitations, not something any eSIM can promise to eliminate.

Our verdict on Holafly

Holafly makes sense if you don't want to monitor your phone's data balance. But if you use under 10GB in a week, a cheaper fixed plan usually gives better value. And for remote work, the daily hotspot limit could be a deal-breaker.

Orange Travel offers more than just tiny tourist packages. Its UK shop lists options from 1GB to large 30-day data allowances, as well as packages that combine data with calls and SMS. The range is useful for a longer trip or a visitor who needs to call UK businesses.

Orange Travel UK plans and prices

• 1GB / 7 days — US$4.49.
• 5GB / 7 days — US$10.12.
• 10GB / 7 days — US$14.62.
• 20GB / 14 days — US$20.24.
• 20GB / 30 days — US$21.37.
• 50GB / 30 days — US$33.75.
• 100GB / 30 days — US$39.37 on the advertised promotion.

These are offers displayed on the UK product page, converted from euros at the ECB rate of October 16, 2026. Orange Travel has separate data-only and data-plus-calls/SMS choices, and the exact bundle contents change when you select those categories. Do not assume the cheapest displayed data price includes unlimited calls.

What about networks and mobile hotspot?

Orange Travel's UK page names partners that include EE, Three, O2 and Vodafone among its network options. Plan-specific network selection may vary. It also advertises hotspot sharing on compatible devices, making a larger fixed-data allowance worth considering if you're working during the trip.

If you need a regular number, check the actual number assigned and the destination rules for calling and texting. You may want calls within the UK, calls home, or both; they're not automatically the same allowance.

Our verdict on Orange Travel

Orange Travel is a particularly interesting option for someone spending a month in the UK or using a laptop part of the time. Its published 20GB and 50GB offerings make a compelling comparison with more expensive unlimited packages.

Jetpac combines prepaid UK data with benefits such as continued access to selected essential apps and its SmartDelay airport-lounge program. Neither benefit matters more than your actual network coverage, but they can be useful bonuses.

Jetpac UK pricing and package options

Jetpac's UK page displays fixed-data plans from 1GB to 40GB as well as unlimited options. When we checked, its discounted 10GB / 30-day offer was displayed as US$0.57 per day — US$17 for the entire plan. Discounts change frequently, so use the final total shown before paying.

Its UK unlimited category advertises a 30-day option and states that the first 3GB per 24 hours is available at standard network speeds. After that, the connection continues at up to 1Mbps until the daily allowance refreshes. That is not the same as 30 days of unrestricted high-speed usage.

What are Jetpac's extras?

• Eligible purchases of at least 3GB include continued connectivity for certain essential apps, including WhatsApp chat, Google Maps, Uber and Grab, after the main data allowance is used. Conditions apply.
• SmartDelay can provide lounge access after a qualifying flight delay if you register the flight in the Jetpac app and meet the program requirements.
• Jetpac's standard UK travel product is data-only. Calls require separate in-app voice packs, not ordinary carrier voice service bundled automatically with the eSIM.

Our verdict on Jetpac

Jetpac is a good option when its discounted total comes in below the equivalent plan from Saily or Airalo. The app-connectivity benefit is reassuring on a busy travel day, but we'd treat airport-lounge access as a bonus rather than the reason to choose a mobile-data provider.

aloSIM offers a surprisingly broad collection of country-specific packages, from short one-day access to month-long plans. Its UK page lists EE and Three as network partners, and the app is built around installing one reusable eSIM profile.

aloSIM UK prices

• 1GB / 5 days — US$4.50.
• 10GB / 5 days — US$12.
• 10GB / 7 days — US$13.50.
• 20GB / 7 days — US$17.
• 10GB / 30 days — US$20.
• 20GB / 30 days — US$32.

These are examples from the site's duration selector, not interchangeable validity periods. When comparing against Ubigi or Nomad, look at the same number of days rather than only the gigabytes.

Does aloSIM give you a UK number?

The provider advertises a complimentary international travel number through Hushed. Think of it as an internet-based calling and messaging product rather than automatically receiving an ordinary local UK SIM number. Coverage, calling credit, number type, verification-code support and validity depend on the current Hushed offer.

If receiving bank SMS or other identity verification is essential, don't assume a virtual number will work. You may need to keep your original carrier number active or choose an eligible package with native calls and texts.

Our verdict on aloSIM

aloSIM is worth checking for a London weekend or a 5–10-day holiday. Its shorter plans can be inexpensive, but if you're staying for three or four weeks, compare a 30-day bundle with Ubigi and Nomad before buying.

Roamless offers three different ways to buy UK data: Flex pay-as-you-go credit, Fix packages with a set gigabyte allowance, and unlimited passes for a chosen number of days. This mix is useful if your trips differ in length.

Roamless UK plans and pricing

• Unlimited / 1 day — US$3.84.
• Unlimited / 3 days — US$11.43.
• Unlimited / 7 days — US$25.62.
• Flex pay-as-you-go — destination-specific rate, balance does not expire.
• Fix packages — separate fixed-data bundles with their own allowance and validity.

Roamless's UK unlimited offer specifies 3GB per day at full speed, followed by 1Mbps until the 24-hour allowance resets. It also lists hotspot sharing as allowed.

What makes Roamless different?

Unused Flex credit doesn't expire, so a small remaining balance can stay in your account until your next trip. This can work well if you're in London for a weekend in March and then Edinburgh for a conference months later.

Its published UK coverage includes Vodafone, O2 and Three on relevant offerings. Roamless also offers optional in-app calling and UK number-related products, but those have their own terms; don't confuse them with calls included in a basic data-only pass.

Our verdict on Roamless

Roamless is appealing if you want a reliable second connection for sporadic trips. For a single two-week holiday with predictable data use, one of the cheaper fixed-data bundles may be a better deal.

Maya's newer global-pass offer is positioned as one eSIM for 165+ destinations, including the United Kingdom. It is useful if London is only one stop in a longer international itinerary and you want fewer SIM changes.

Maya global pass prices including the UK

• Unlimited / 3 days — US$9.99.
• Unlimited / 7 days — US$19.99.
• Unlimited / 14 days — US$27.99.
• Unlimited / 30 days — US$49.99.

The published prices above are for Maya's global land-travel plan rather than a UK-only fixed 10GB package. That means the convenience is wider destination coverage, not necessarily the lowest price for one country.

Is Maya really unlimited?

Maya markets its new global product as unlimited and promotes hotspot availability. However, published unlimited-plan support and fair-use guidance can vary by product generation. Review the current specific pass terms for speed management, usage patterns, and tethering before treating it as an unlimited high-speed replacement for home broadband.

For a short city break with light data use, you'll probably save money with a fixed package. Maya becomes more interesting if you routinely travel between countries and prefer an easy recurring global setup.

Our verdict on Maya Mobile

Maya is worth comparing with Holafly or Roamless for longer international trips. For London alone, we'd start with Ubigi, Saily or Nomad first, unless you genuinely expect to use a lot of data.
