Policies compared

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

ID verification

co:sim: Not confirmed yet

Tripuck: Not required

Refund policy

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

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

co:sim: Not confirmed yet

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

co:sim: Daily plans throttle to a lower speed (e.g. 512Kbps) once the daily limit is reached; total-data plans simply stop once depleted.

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).

Top-ups & rollover

co:sim: Top up your balance anytime on the website -- instant, choose from various amounts; PAYG deducts per MB, data packages from $0.90/GB.
