Cheapest & Best UK eSIMs: Top 9 Providers Compared
Nine UK eSIM providers compared on listed prepaid data prices, fixed allowances and validity, so you can match a plan to your trip length.
The dated comparison tables below reflect the observation date recorded for each figure and are not a guarantee of current pricing.
How we compared UK eSIM prices
Airwaily publishes this comparison and sells one of the nine products in it, so weigh the figures with that in mind. I set out to see what each provider's cheapest eligible UK offer costs once allowance and validity are read together: 1 GB for 7 days and 1 GB for 30 days solve different problems at different totals. Each of the ten tables applies one allowance rule, from an exact 1 GB to at least 30 GB over 60 days, and qualifying regional competitor plans stay labelled as such.
Exact 1 GB: who charges least
Airwaily's 1 GB plan lasts 7 days and costs $0.76. Yesim's 1 GB stretches to 30 days at $2.23, MobiMatter's 1 GB runs 14 days at $3.49, and Airalo's cheapest exact 1 GB covers just 3 days at $3.60.

At least 15 GB: larger packages compared

Airwaily's $18.88 is 76.1% less than Nomad's 30 GB over 365 days at $79 and 46% less than MobiMatter's 30 GB over 365 days at $34.99. The data allowance matches, but the rivals extend validity by roughly ten months.
Which UK eSIM should you buy?
The allowance tables point the same way for ordinary trips: Airwaily's 1 GB over 7 days at $0.76, 5 GB over 15 days at $1.79 and 10 GB over 30 days at $3.40 are the lowest listed totals in their groups, and its 50 GB over 30 days at $15.90 undercuts every recorded 50 GB rival. The trade-off is time rather than data. A longer stay or a plan kept for a return visit is better served by GigSky's 50 GB over 180 days at $27.11 or MobiMatter's 30 GB over 365 days at $34.99, which charge more upfront but hold the line far longer. My recommendations split on exactly that: Airwaily for a normal-length visit, a longer-validity rival when the clock is the constraint.
How to read these UK eSIM prices
Prices are USD observations dated 11 November 2026 for Airwaily and 8 November 2026 for the eight competitor records. Some competitor amounts were converted from the currency their shop displays, and supplied promotions are already inside the figures rather than applied afterwards. Each table selects one cheapest eligible paid fixed-allowance data-only offer per provider, excluding free trials, subscriptions and daily-reset bundles. A blank entry means no qualifying offer existed in this nine-provider comparison, not that a provider ignores the UK.
