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.

RoamGo: All sales are final once the eSIM is installed or activated. A refund or replacement is granted where the eSIM failed to activate because of a verified technical fault, after support was given a chance to troubleshoot. Requests must reach support within 30 days of purchase. No refunds for an incompatible or locked device, skipped install instructions, a deleted profile, data already used, or changed travel plans.

Validity starts

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

RoamGo: The validity period starts at the activation event named on each product page, and it genuinely differs per plan: some start on successful payment, others on installation, manual activation, or first connection to a supported network. Each plan page states which rule applies before you buy.

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.

RoamGo: Fixed-data plans are one bucket for the whole trip - no daily reset and no throttling until the bucket runs out. RoamGo also sells daily-allowance plans, which run at reduced speed after each day's high-speed cap; those are not listed here. Their Terms state that advertised speeds are theoretical maximums from the local carrier, not guaranteed throughput.

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.

RoamGo: Top-ups are per plan, not provider-wide: each plan page says "Top-ups available" or "No top-ups on this plan", and RoamGo state they make no promise where the carrier has not confirmed. Where a top-up applies it reuses the same eSIM and QR code with no reinstall, and is priced separately by the carrier. Some plans stay eligible for a limited grace period after expiry.

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.

Billing currency

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

RoamGo: Prices are charged in USD. The price shown on the site is converted to the visitor's local currency for display only, marked with a "~". Card checkout has a $5 minimum; smaller orders need crypto or account balance.
