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.

FlexiRoam: Full refund if no data was used and a FlexiRoam technical fault could not be fixed during the trip (partial if data was used); partial refunds for intermittent service or downtime. No refund for unused data at expiry, device incompatibility/lock, or an installed plan bought by mistake. 5% admin fee; request within 120 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).

FlexiRoam: Validity starts when you activate the plan or on a start date you schedule; a plan not activated within 90 days of purchase activates automatically (Terms §3.3, §3.6).

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.

FlexiRoam: Unlimited plans have a daily high-speed limit (3GB on the product pages); after it the speed is capped or the service pauses until the next day (Terms §21.2). Throttled speed not stated.

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.

FlexiRoam: Buy another plan onto the same eSIM in the app or website; buying the same plan again before it expires extends it and rolls unused data over where the plan includes Data Rollover (Terms §23).

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.

FlexiRoam: Reinstall the existing eSIM on the same or a new phone from the app (Account > My SIMs > Install); support helps if the old device is unavailable.

Billing currency

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

FlexiRoam: Charged in USD, or another currency you select on the site (Terms §3.9).
