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.

The SIM Shop: Unused, uninstalled and unactivated plans can be refunded within 30 days of purchase from My Account > Refunds, to the original payment method. Installed, activated or used eSIMs are reviewed case by case. Australian Consumer Law rights apply on top.

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.

The SIM Shop: Validity starts on first network connection on almost every plan; Japan KDDI plans start on first data use in Japan, with a supplier start-by deadline.

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.

The SIM Shop: Daily high-speed plans slow down after the daily allowance (typically to 384 kbps) until the next reset; the allowance, reduced speed and hotspot limits are stated per plan.

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.
