Refund policy

Billion Connect: Refundable before activation; once activated/used, refund rights end; third-party partner purchases are excluded from refunds.

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

Billion Connect: Most plans start when the eSIM first connects to a supported network at your destination (some start on installation, as the product page states); activate within 90 days of purchase; a day = 24 hours from activation.

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

Billion Connect: Set per plan on the product page: most plans drop to a reduced speed (typically 128–384 kbps) after the high-speed allowance, daily or total, instead of cutting off; a few plans stop at the limit.

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

Billion Connect: Standard eSIMs can't be topped up; buy a new plan when data runs out. eSIM Air supports top-ups anytime without reinstalling.

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).
