Simbye: Full refund for an eSIM not installed, activated or used if requested within 30 days of purchase; partial or full refund if it doesn't work because of Simbye or the network, even after installation. Applied top-ups are 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).
Simbye: Plan validity (7–90 days) starts when the eSIM connects to a network at your destination; until then the eSIM stays valid for 180 days. Some plans, such as the US eSIM with a phone number, start at 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.
Simbye: Unlimited plans include 2GB of high-speed data per day, after which speeds are reduced until the next 24-hour cycle.
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.
Simbye: Top up on the top-up page or in your account with your order number: buy a new data package and the same eSIM reactivates instantly, no reinstall needed.
