Refund policy

esimgenius: Full refund only if the eSIM never activates in the destination country (install/connect failure, incompatible/carrier-locked phone, or the supplier under-delivers data). Wrong-destination purchases are case-by-case if reported within 24h, not guaranteed. Refunded via Stripe within 1 business day (banks take 5-10 more days).

Simsima: Full refund if the eSIM hasn't been installed/activated, there's a technical failure on Simsima's side, or the wrong plan was delivered — not available once installed and connected to a network.

Validity starts

esimgenius: Validity starts at first network connection, not at purchase. An installed-but-never-activated eSIM is held for 90 days by their supplier before the QR can expire.

Simsima: Starts when the eSIM first connects to a network in the destination country, not at installation — you can install days or weeks ahead without losing validity.

Fair-use limit

esimgenius: Unlimited plans state no daily data caps or cutoffs from esimgenius itself, but local carrier partners may throttle/restrict on atypical usage as an anti-abuse measure -- no specific threshold stated.

Simsima: No fair-use throttling on Unlimited plans — full speed for the entire validity period; only real network conditions may vary speed.
