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
GigSky: 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.
GigSky: SIMs and top-ups can't be returned once sold and unused data isn't refunded; a minimally used subscription plan (under 1GB) affected by a connectivity issue may be refunded at GigSky's discretion.
Validity starts
4S: Most plans start counting on first use, when the eSIM connects and begins using data (checked on your 4S service page).
GigSky: Plans are turned on by the customer when ready to travel, not automatically at purchase, per GigSky's setup flow ('Activate When You Travel, Top Up Anytime').
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.
GigSky: On Unlimited plans, GigSky may reduce speed during a single day of very heavy use (e.g. video streaming); normal speed resumes the next day. No specific data threshold or throttled speed is disclosed.
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.
GigSky: Eligible plans can be topped up anytime in the GigSky app (My Plans > Top Up), with the data added to the existing plan; not every plan supports top-ups and complimentary Visa plans can't be topped up.
