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.

Roam2Go: Full refund within 30 days of purchase if the eSIM hasn't connected or used any data (installing it doesn't count as use). If it doesn't work, a free replacement first, and a full refund if it can't be fixed within 10 days.

Validity starts

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

Roam2Go: On most plans validity starts when the eSIM first connects to a network in a covered country; on some plans it starts at installation (the eSIM email says which). Some plans have a maximum period from purchase to start using it.

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.

Roam2Go: Unlimited plans are never cut off: 1–10 GB a day at full speed depending on the plan, then usually 1–10 Mbps for the rest of the day, resetting daily. Some unlimited plans have no daily cap, up to 10 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.

Roam2Go: On plans that support it, top up the same eSIM from "My eSIMs"; depending on the plan the top-up is queued until the current plan ends or added to it. Unused data doesn't carry over.

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.

Roam2Go: Depends on the plan: some can be reinstalled a limited number of times on the same phone, others only once (the QR email says which). A deleted eSIM can't be recovered; a free replacement is given for technical faults.

Billing currency

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

Roam2Go: Prices in EUR by default. If you choose or are shown USD, GBP or CAD, the price is converted at their daily rate and charged in that currency; your bank may add its own fees.
