Policies compared

Confirmed from each provider's own site — see the trust card on each provider page for the verification date.

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).
