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.

Eskimo: ESKIMO GUARANTEE: if you cannot install the eSIM or connect to the network, contact 24/7 live chat for immediate verification and refund. Once connected, any remaining data balance is non-refundable if the account is later cancelled or terminated.

Validity starts

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

Eskimo: Data plans have no expiration date. Validity starts when the eSIM first connects to a supported network (or transfers data), and the remaining balance never expires unless the account itself is cancelled.

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.

Eskimo: Fixed data plans have no daily caps or throttling (full speed); Unlimited day passes give 3GB high-speed per day, then unlimited at 1 Mbps.

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.

Eskimo: Top up from the Eskimo app or website: the new plan is added instantly to your existing eSIM with no reinstallation and kicks in when the current plan reaches 0 MB.

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.
