Refund policy

AeriSIM: Full or partial refund, or a replacement, if the eSIM can't be installed or used due to a fault on AeriSIM's or the carrier's side; incompatible or carrier-locked phones are refunded minus $2 or 10% (whichever is higher). No refund once installed, for changed plans, or after the activation window.

ZetSIM: An eSIM that has not been activated and whose plan is still valid is refunded in full, with no fee, as refund coins (store credit in the same currency, never expires, not withdrawable as cash). No refund once activated or for unused data.

Validity starts

AeriSIM: Validity starts once the eSIM connects to a supported network and begins using data; you can install before departure but keep it switched off. Some plans start on installation or a fixed date, as stated on the product page.

ZetSIM: Validity starts when the eSIM first connects to a local network at the destination, not at purchase.

Fair-use limit

AeriSIM: Varies by plan and is listed on each product page: daily plans slow down after the daily high-speed allowance (e.g. Japan: 128 kbps, resets 0:00 UTC+8); some unlimited plans have a stated speed cap instead.

ZetSIM: Unlimited plans: 2GB of high-speed data per day, then 256 kbps; the daily allowance resets every 24 hours from first connection.

Top-ups & rollover

AeriSIM: Depends on the plan: check My eSIMs and the order details; if a top-up is not offered, buy another plan for the same destination.

ZetSIM: Add a new plan to the eSIM you already installed: no new QR code, no reinstall.
