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.

NXTL: Purchases are generally final once the eSIM is delivered; duplicate payments and non-delivery are refunded, and NXTL advertises a connectivity guarantee — if support can't get you connected in a supported destination, you get a refund.

Validity starts

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

NXTL: NXTL is pay-as-you-go with no bundle expiry - purchased balance never expires and carries over to future trips instead of counting down from a fixed validity period.

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.

NXTL: Not confirmed yet

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.

NXTL: Balance top-ups are managed entirely from your account at nxtlsim.com, no app or profile reinstall needed, and credit the moment payment clears.

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.

NXTL: NXTL's setup guide says not to delete an installed eSIM unless support tells you to, and deleted profiles aren't refundable per its Terms -- there's no self-service reinstall option, so contact support directly.

Billing currency

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

NXTL: Checkout defaults to USD but a currency switcher lets you view and pay in EUR or GBP; your own card issuer may still apply a foreign-transaction fee.
