eSIMInsight is an independent travel eSIM price comparison and verification service. We track live pricing for ${dests.length} destinations across ${DATA.providers.length} providers and publish verified cost-per-GB, network coverage and promo-code status. All prices are re-verified on an official crawl cadence (every 3 days); every page carries its own data review date.
Prices and plans are collected from official provider plan pages and publicly available sources (e.g., official pricing pages and public comparison data), plus provider partner feeds where available. Every collection run stores a compressed page snapshot as evidence; plan entries keep their source URL and verification timestamp.
A scheduled collection job runs every 3 days. Each destination is advanced to the current review date only when at least one of its official sources was successfully fetched in that run; destinations whose sources all failed keep their previous review date and are flagged by a 14-day freshness gate that blocks publishing stale data.
The overall score is: price per GB 60% + network coverage 20% + hotspot support 10% + app quality 10%, normalized within each destination (so plans in different destinations do not interfere). Unlimited plans are treated with a neutral price score and shown with their fair-use policy (FUP). Rankings are computed from cost per GB and coverage — not by affiliate commission.
We may earn a commission when you buy through links on this site. It does not change the price you pay, and it does not change our ranking: plans are ordered by cost per GB and measured speed only. Affiliate links are marked and use nofollow sponsored attributes.
We only publish platform-official codes or codes issued under our own affiliate accounts. Third-party creator codes are never listed, because they redirect commissions away from the site. Each code shows its last verification date; codes that stop working are marked expired rather than silently removed.
Official sources are pinned to their declared domains; the collector refuses to follow redirects outside the allowlist. Unparseable or ambiguous pages are never guessed — they are saved as evidence and queued for human review. A failed collection run keeps the last verified prices instead of overwriting them with empty results. Every release runs automated checks (data integrity, freshness, i18n, link validity, machine-readable feeds) before deploy.
If you spot a wrong price or a broken detail, open an issue at github.com/sdpku/esiminsight2/issues — we correct verified data and note the change.
