Refund policy

Always Mobile: 30-day refund policy from receiving the QR code, as long as the eSIM data plan is unused. Once installed and any data is consumed, the eSIM is non-refundable.

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

Always Mobile: Validity starts when the eSIM first connects to the local network at the destination, not at purchase.

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

Always Mobile: Fixed-GB plans have no daily cap. Daily Unlimited plans include a fixed full-speed GB allowance per day, then throttle to a reduced speed (per-plan text on the site states a range, typically 384-512 Kbps, or a specific Mbps figure) until the next 24-hour reset.

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

Always Mobile: Top-up availability is set per plan (most fixed-GB and some Unlimited plans can be topped up via the link in the QR-code email; Daily Unlimited plans generally cannot).

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).
