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.

MicroEsim: Conditional refund: full/partial if your device is eSIM-incompatible, the eSIM never connects (full minus a small admin fee), or it works only intermittently (partial, prorated). No refund once the plan has expired unused, once installed on a device (no transfers), for a wrong checkout email, or a simple change of mind. Approved refunds go back to the original payment method, up to 30 business days.

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.

MicroEsim: Validity starts when you activate data roaming on the eSIM (connect to the network), not when you first install/add it to the device.

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.

MicroEsim: Unlimited plans: 'true unlimited' plans may be throttled for the rest of the day once usage typically exceeds 10GB in a single day (resets daily); plans with a high-speed cap drop to 128kbps once that allowance is used.

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.

MicroEsim: No — an existing eSIM's data allowance can't be renewed or topped up; buy a new eSIM for more data (per their FAQ).
