ZenSim: Not required

Refund policy

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.

ZenSim: Refunds are not available once the eSIM has been installed or activated, except for a technical failure verified by ZenSim. If a Travel eSIM cannot be used due to device incompatibility, a refund is issued only if it has not been installed/activated on a different device.

Validity starts

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.

ZenSim: Validity starts on activation, not purchase — the eSIM auto-activates the first time it connects to the destination network. Must be installed within 12 months of purchase or ZenSim may cancel the order.

Fair-use limit

MicroEsim: A fair-use clause in their Terms lets the carrier throttle/control data if usage negatively impacts network experience for other users; per-plan, many plans also state a real post-cap throttle speed rather than a hard cutoff (see each plan's own fair-use note).

ZenSim: Unlimited plans include a fixed daily high-speed allowance (see each plan), then drop to a reduced speed for the rest of that day.

Top-ups & rollover

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).

ZenSim: Every Travel eSIM can be topped up from the ZenSim app — no need to buy a new eSIM.
