Refund policy

HelloRoam: Full refund on an unactivated eSIM within 6 months of purchase (QR not scanned, no data used). Also covers device-compatibility issues and major service/connection failures (partial or full refund).

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

HelloRoam: Plan days start only at the eSIM's first connection to a supported network in your destination — buying and installing it at home use no plan days.

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

HelloRoam: A fair-use policy applies to unlimited plans — HelloRoam may apply speed limits if usage is well above normal levels, to protect network quality for other users.

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

HelloRoam: Top up an existing eSIM in the HelloRoam app (My eSIM > Top up): the new data joins what's left and the end date moves out on the same eSIM, no new QR code; expired eSIMs and some plans can't take a top-up.

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).
