Policies compared

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

ID verification
4S: Not confirmed yet
Airalo: Required for some countries (passport/ID)
Refund policy
4S: Refund eligibility is reviewed case-by-case based on order/eSIM status and reason — no fixed window stated; contact support to request review.
Airalo: Self-service refund request from your account (My eSIMs > Package History > Request Refund) for wrong purchase, changed plans, installation issues, or a non-working eSIM — expired or fully-used eSIMs aren't eligible. Wrong-purchase/changed-plans refunds go to Airmoney (their in-app credit) only; installation-issue/not-working refunds can go to Airmoney or your original payment method, taking 7-10 business days (up to 30 depending on your bank).
Validity starts
4S: Most plans start counting on first use, when the eSIM connects and begins using data (checked on your 4S service page).
Airalo: Validity starts either when the eSIM connects to the destination network or at the moment of installation, depending on the specific plan — check 'Additional Information > Activation Policy' on the plan page before buying to see which applies.
Fair-use limit
4S: Unlimited plans include a high-speed data quota for the full validity period; after it is used, speed drops to up to 1 Mbps until the plan expires.
Airalo: Unlimited plans default to a 3GB-per-day full-speed allowance before throttling to 1 Mbps for the rest of that 24-hour period (counted from activation, not purchase); a different daily threshold is stated on the specific plan's page when it applies instead of the 3GB default.
Top-ups & rollover
4S: Self-serve top-up (same destination/region only) adds high-speed data to the current plan and extends its validity by the top-up package's own validity period.
Airalo: Only plans marked 'rechargeable' (checkable under Additional Information before buying) can be topped up, via the My eSIMs > Top Up option in the app — a non-rechargeable eSIM or one that changed carriers requires buying a new eSIM instead.
