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.

Revo: Refunds only if the eSIM has not been installed, activated, scanned or used, requested within 14 days of purchase; a defective eSIM or one failing through an error on their side may get a replacement or refund after verification, paid back to the original method within 3 business days.

Validity starts

4S: Most plans start counting on first use, when the eSIM connects and begins using data (checked on your 4S service page).

Revo: The eSIM can be installed days or weeks ahead of a trip while inactive — it only activates once you land and connect to a local network at your destination, not at install or purchase.

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.

Revo: Unlimited plans keep working at a reduced 1 Mbps once the daily high-speed allowance is used; the size of that daily allowance is not stated sitewide.

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.

Revo: Existing eSIMs can be topped up directly on the Revo eSIM site using the eSIM's ICCID number — no new profile install or settings change needed, applies within a few clicks.

Lost device / reinstalling

4S: Each eSIM QR/activation code can only be installed once; a deleted eSIM usually cannot be reinstalled with the same code — contact support for a replacement.

Revo: eSIM QR codes can typically only be scanned once for security -- if accidentally deleted, contact support via WhatsApp for a replacement.

Billing currency

4S: Checkout supports multiple currencies (USD, EUR, GBP, JPY, CNY and others via a currency selector); USD is the default.
