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
Giga.tel: Not confirmed yet
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.
Giga.tel: Full refund only if the eSIM hasn't been installed and no data was used - contact within 5 days of purchase with your order number. If a technical issue (won't download, won't connect) can't be resolved, a refund/partial refund may still be given.
Validity starts
4S: Most plans start counting on first use, when the eSIM connects and begins using data (checked on your 4S service page).
Giga.tel: Standard eSIM plans: validity starts when the plan is activated, not at purchase (confirmed at checkout). A separate 'Connectivity' plan type instead starts immediately after 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.
Giga.tel: Unlimited plans carry a fair-use policy - each plan's own page shows its Daily Allowance and the post-threshold speed; there's no single sitewide GB/day figure or throttle speed.
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.
Giga.tel: Add a top-up or a new plan to the same reusable eSIM at any time without reinstalling - just keep the eSIM profile on your device rather than deleting it.
