4S MoodSIM

ID verification

4S: Not confirmed yet

MoodSIM: Not required

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.

MoodSIM: Not installed and within 14 days of purchase: full refund. Once installed (QR code scanned or one-tap install used): non-refundable. Top-ups and cryptocurrency payments are always 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).

MoodSIM: Shown per plan: "Upon Connect" plans start validity on first network connection at the destination (can install ahead of time); "Upon Install" plans start the moment the QR code is scanned. All eSIMs must be installed within 180 days of 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.

MoodSIM: Some plans apply a fair usage policy (mainly the daily-unlimited plans) — speed is reduced after the stated daily high-speed allowance, per the plan's own details. Not grounds for a refund.

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.

MoodSIM: Top-ups add both data and validity time. Optional auto top-up recharges automatically once remaining data falls below ~300MB, charging the saved card the plan's original price; a failed charge disables auto top-up rather than retrying. Not every plan supports top-up (shown per plan).

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.

MoodSIM: If you delete the eSIM by accident, try re-scanning the original QR code on the same device (some profiles allow reinstall); otherwise contact support with your ICCID. eSIMs can't be moved to a new phone, which needs a new eSIM.

Billing currency

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

MoodSIM: Prices are shown in USD. At checkout you can pay in your local currency (Stripe adds a roughly 2-4% conversion fee) or in USD (your own bank's exchange rate/foreign-transaction fee may apply instead) — the underlying price is identical either way.
