Policies compared

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

ID verification

Roamify: Not required

ZetSIM: Not confirmed yet

Refund policy

Roamify: Unused/unactivated eSIM purchases are eligible for review within 7 calendar days of purchase (must not be activated, installed, or consumed). Approved refunds are issued within 3 business days; banks/card networks may take a further 5-10 business days to post funds.

ZetSIM: An eSIM that has not been activated and whose plan is still valid is refunded in full, with no fee, as refund coins (store credit in the same currency, never expires, not withdrawable as cash). No refund once activated or for unused data.

Validity starts

Roamify: Service begins immediately once the eSIM is downloaded and its data plan activated — validity starts on activation, not at purchase.

ZetSIM: Validity starts when the eSIM first connects to a local network at the destination, not at purchase.

Fair-use limit

Roamify: Unlimited plans are subject to a stated Fair Use Policy (preventing fraud/abuse), but no numeric high-speed cap or throttle speed is published — Roamify reserves the right to suspend/throttle without a stated threshold.

ZetSIM: Unlimited plans: 2GB of high-speed data per day, then 256 kbps; the daily allowance resets every 24 hours from first connection.

Top-ups & rollover

Roamify: Top-up is available in-app for supported eSIMs (not all — the app itself states when a plan can't be topped up), up until 2 hours before the plan expires.

ZetSIM: Add a new plan to the eSIM you already installed: no new QR code, no reinstall.
