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.

Always Mobile: 30-day refund policy from receiving the QR code, as long as the eSIM data plan is unused. Once installed and any data is consumed, the eSIM is 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).

Always Mobile: Validity starts when the eSIM first connects to the local network at the destination, not at purchase.

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.

Always Mobile: Fixed-GB plans have no daily cap. Daily Unlimited plans include a fixed full-speed GB allowance per day, then throttle to a reduced speed (per-plan text on the site states a range, typically 384-512 Kbps, or a specific Mbps figure) until the next 24-hour reset.

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.

Always Mobile: Top-up availability is set per plan (most fixed-GB and some Unlimited plans can be topped up via the link in the QR-code email; Daily Unlimited plans generally cannot).

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.

Always Mobile: The eSIM can be installed on one device only and re-scanned multiple times on that same device, but cannot be transferred to a different device.

Billing currency

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

Always Mobile: Billed in USD (Shopify store, native USD pricing).
