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.

Dingo: No refund on a used or unused data plan once sold, except (a) the eSIM fails to activate due to a technical fault on Dingo's or the network's side, or (b) the buyer withdraws within 14 days before the eSIM Service has been activated. Disputed/chargeback purchases get the account blocked rather than refunded. Complaints must go to [email protected] within 2 months; Dingo responds in writing within 1 month.

Validity starts

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

Dingo: The eSIM must connect to the network within 365 days of purchase for its validity period to start; each data session is rounded up to 100KB.

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.

Dingo: Unlimited plans throttle to a reduced speed (commonly 1 Mbps) after a daily high-speed data cap that varies by plan and destination — stated per plan.

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.

Dingo: Available — top up anytime after data runs out or the validity period expires; auto top-up can be enabled.

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.
