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.

AirPlans: Full refund within 30 days if the eSIM was never installed or activated, wasn't delivered, or had a verified unresolved technical failure; installed plans and wrong-destination purchases are non-refundable.

Validity starts

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

AirPlans: Validity starts when the eSIM connects to a network abroad, not at purchase or installation.

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.

AirPlans: Unlimited plans come with a daily high-speed allowance (1GB, 2GB or 3GB per day depending on the plan), after which speed drops to a stated rate (512 Kbps to about 2 Mbps) until the next day. Both figures are published per plan in their feed and shown on each plan row here.

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.

AirPlans: Existing eSIMs can be topped up with more data from the My eSIMs screen in the app, no reinstall needed.

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.

AirPlans: A deleted AirPlans eSIM cannot be reinstalled with the same QR code/activation code -- each code works only once, so contact support before deleting anything if you might need it again.

Billing currency

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

AirPlans: Checkout shows prices in your chosen currency, with the exact amount and currency charged confirmed before you pay.
