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
eSIMCard: Not required
Yesim: Not required
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.
eSIMCard: No refunds once the eSIM is installed and used; refunds within 30 days for coverage issues preventing installation, technical problems with no data consumed, or unauthorized purchases.
Yesim: Refunds for data plans and top-ups within 30 days of purchase, excluding plans already used or expired; refunded to the original payment method.
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).
eSIMCard: The eSIM activates automatically when the first byte of data is consumed at the destination, not at purchase, so it can be bought and installed well in advance.
Yesim: You select a desired activation time when purchasing a plan in the app -- validity is not automatically triggered at purchase.
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.
eSIMCard: Unlimited bundles include an allowed amount of full-speed data per rolling 24-hour period (starting from first use), after which speed drops for the rest of that period before resetting.
Yesim: Yesim itself does not enforce a Fair Usage Policy on its Unlimited plans, but some of its partner network providers may apply their own FUP as part of their own terms, per Yesim's Help Center.
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.
eSIMCard: Existing eSIMs can be topped up or extended with more data through the eSIMCard app, which also lets you manage active plans.
Yesim: Additional data can be bought at any time from the Yesim app or website, added to the same eSIM.
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.
