Refund policy

CloudOn: Full refund only if never installed/activated, requested within 30 days of purchase. Once activated: generally non-refundable, except a partial refund for unused data if usage is minor AND a verified network/technical failure prevented service. Discount-code purchases are non-refundable once activated. DTAC Thailand 50GB/10-day and Unlimited plans follow a separate, per-plan 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.

Validity starts

CloudOn: Validity starts on first network connection, not at purchase or installation - a 7-day plan installed a week early still gives the full 7 days once first connected.

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

CloudOn: Unlimited plans include a fair-use high-speed data allowance before speeds are reduced for the rest of the validity period - the exact threshold and reduced speed vary by plan and are stated on that plans own page.

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

CloudOn: Supported - top-ups add to the existing eSIM directly from the CloudOn account, no new QR code or reinstall needed.

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).
