- Headquarters
- Bangkok, Thailand
- Legal entity
- Alphaweb Ventures Limited
- Website
- esimgenius.ai
- Refund policy
- 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). Read the policy ↗
- Validity starts
- 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.
- Fair-use limit
- 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.
- Billing currency
- USD only, tax-inclusive, charged via Stripe -- no other currency option found at checkout.
