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.

ASimGo: Full/partial refund or free replacement for a verified technical failure or persistent connectivity issue; a locked/incompatible device costs 2.50 USD or 10% (whichever is higher). No refund for change of mind, a deleted profile, expired data, a wrong email or a lapsed 30-90-day activation window.

Validity starts

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

ASimGo: Most plans activate only when the eSIM first connects to a supported network, not on purchase — install it just before departure or on arrival using airport Wi-Fi, per their FAQ.

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.

ASimGo: 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.

ASimGo: Not confirmed yet

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.

ASimGo: A deleted eSIM profile cannot be recovered or resent — removal is permanent once installed, per their FAQ. Contact support if this happens before travelling.

Billing currency

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

ASimGo: Feed and checkout prices are in USD.
