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.

co:sim: Uninstalled eSIMs refunded unconditionally within 30 days of purchase; once installed, refundable only for a technical issue on co:sim's side.

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.
