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

ID verification

Roamify: Not required

SimSmash: Not required

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.

SimSmash: Full refund if the eSIM has not been activated. Once activated, a partial refund pro rata to the unused data is offered within 24 hours of purchase. Contact support.

Validity starts

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

SimSmash: Validity starts on activation, not on purchase; the eSIM can be bought up to 30 days before departure.

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.

SimSmash: Not confirmed yet

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.

SimSmash: Some plans can be topped up directly when the Top-Up option is shown; otherwise buy a new plan, delivered by email immediately.
