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.

MegaEsim: 100% money-back guarantee: ask within 6 months of purchase for any reason (installed, partly used or not) and get a full refund within 3-5 business days. Only exception: plans with a phone number are non-refundable. EU/EEA/UK buyers also keep the 14-day withdrawal right unless waived.

Validity starts

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

MegaEsim: Validity starts on first network connection at the destination, not at purchase or installation — installing the eSIM before a trip doesn't start the clock.

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.

MegaEsim: Daily-cap "Unlimited" plans run at full speed up to their stated daily allowance, then throttle (per-plan capacityInfo, typically to 1 Mbps) until the next 24h 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.

MegaEsim: Top up anytime from your MegaEsim account or app (My eSIMs → Top Up); extra data is added to the same eSIM with nothing to reinstall. A few plans, such as some daily unlimited plans, can't be topped up.

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.

MegaEsim: Each QR code can normally only be installed once; if deleted, contact support and they re-issue a fresh QR code at no extra charge.

Billing currency

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

MegaEsim: Prices are shown and charged in USD (confirmed via the site's own product schema); your card issuer may apply its own FX/foreign-transaction fee.
