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.

nadanada: eSIM purchases are generally non-refundable once the eSIM profile has been delivered and used; for technical issues contact support — a refund is possible in that case, but the data is lost (Terms §5).

Validity starts

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

nadanada: A bundle starts on the first connection to a supported network in its country/region and ends when the data or the days run out. Terms: bundles must be activated within 6 weeks of purchase; the eSIM stays valid for 6 months after its last connection, and every connection extends it by 6 months.

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.

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.

nadanada: Top-ups can be added to the existing eSIM at any time and queue consecutively: the current bundle runs until it expires, the new one activates afterwards, and no remaining days or data are lost (FAQ).

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.
