Policies compared

Confirmed from each provider's own site — see the trust card on each provider page for the verification date.

ID verification

ASimGo: Not confirmed yet

Tripuck: Not required

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.

Tripuck: Unused eSIMs can be refunded on request within 7 days; no refund once activated. Refunds go back to the original payment method within 14 business days.

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.

Tripuck: Validity starts on first connection to a network at the destination, not on installation. Exception: a few North America calling plans run from a travel start date chosen at checkout (labelled there).

Fair-use limit

ASimGo: Not confirmed yet

Tripuck: Set per plan, not one company-wide policy. Daily-cap Unlimited plans: a stated high-speed amount per day, then reduced speed. Per-trip Unlimited plans: first 500 MB at full speed, then 5 Mbps, then 512 Kbps near a hard ceiling (30/45/70 GB for 7/15/30 days).
