The method behind the verdict
Clear prices.
Clear reasoning.
Greater eSIM calculates these price comparisons from collected provider listings. The results cover the four named providers and the matching plans shown.
One plan means one exact match.
Same destination, total GB, number of days, and USD currency. We include every combination shared by at least two providers in the collected fixed-data plans. Unlimited, daily-reset, regional, top-up, and voice/SMS plans are excluded.
The lowest recorded price wins.
At least two providers need a matching price, and all four source inventories must pass the snapshot checks for completeness and age. Ties share the lowest price. Verdict savings use the most expensive matching offer shown; the table gives the difference for every priced provider. Matching data and days does not establish equal network coverage, speed, or support.
Check the sources and dates.
Airalo, Saily, and Nomad prices come from their public country pages; PikoeSIM prices come from its public catalog. Source links open provider country pages, with original observation dates beside them. The snapshot was compiled 17 October 2026; collection times can differ. Prices may vary by location, promotion, taxes, or checkout. Other sales channels are outside this comparison.
Before you go
A few things you
might be wondering.
Who wins the eSIM price comparison for United Kingdom eSIM?+
For United Kingdom, PikoeSIM is cheapest in 8 of the 14 selected comparisons and Saily is cheapest in 6 of the 14 selected comparisons. These results apply to the recorded prices, data allowances, and validity periods shown below. They are price comparisons, not service ratings.
How do you choose a winner?+
We include every data-and-validity combination shared by at least two providers in the collected fixed-data plans. For each destination, the lowest recorded USD price wins among the matching offers shown, with ties shared. We withhold verdicts when any of the four provider sources is missing or incomplete. These rankings cover only the named providers and matching plans.
Why do some cells say “No exact match” or “Not verified”?+
No exact match means the collected plans did not include that exact combination of data and days. Not verified means the source was incomplete, too old for the snapshot checks, or did not provide a usable price. Neither label proves a provider has no other plan.
Are these the prices I will pay?+
These are recorded public USD prices from the snapshot compiled 17 October 2026. The original observation date appears beside each source link. Promotions, visitor location, taxes, and checkout prices may differ. Check the provider page before buying.
Does the lowest price mean the best eSIM service?+
The verdict compares price for the stated data allowance and validity. It does not assess network coverage, speed, reliability, device compatibility, or customer support. Check those details with the provider before choosing a plan.
Who publishes these comparisons?+
Greater eSIM publishes the plan tables, price verdicts, and country summaries. They are calculated automatically from collected provider prices using the matching and ranking rules on this page. The source links identify the providers behind the recorded prices.
