Refund policy

ASimGo: Full/partial refund or free replacement for a verified technical failure or persistent connectivity issue; a locked/incompatible device costs 2.50 USD or 10% (whichever is higher). No refund for change of mind, a deleted profile, expired data, a wrong email or a lapsed 30-90-day activation window.

Lempart Flex: Full refund on request while the eSIM has not been issued, and always in full if it could not be activated in its coverage area through no fault of yours. If you asked for immediate issue at checkout, an issued plan is not refundable; otherwise there is a 14-day withdrawal right, refunded less a proportionate amount for data used.

Validity starts

ASimGo: Most plans activate only when the eSIM first connects to a supported network, not on purchase — install it just before departure or on arrival using airport Wi-Fi, per their FAQ.

Lempart Flex: Validity normally starts when the eSIM first connects to a network in its coverage area (Terms §6); the plan must be installed within the period stated on it, usually 180 days from purchase.
