Refund policy

ByteSim: Full or partial refund for connection issues, depending on the situation; no cancellation fees and a money-back guarantee (ByteSIM FAQ). Full terms are on their Refunds Policy page.

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

ByteSim: Most plans start when the eSIM first connects to a network at the destination; some start on a selected date, in the app or (e.g. the Giffgaff UK eSIM) from purchase, as stated on the product page. Installing early usually does not start the plan; some QR codes must be used within 180 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

ByteSim: Unlimited plans may be subject to a local operator fair-use policy: heavy use in a short period can be temporarily slowed or deprioritised (1080p streaming still possible), lifted the following day. The per-plan speed policy is stated on each product 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

ByteSim: No top-ups or extensions: data on an existing eSIM cannot be renewed; buy a new eSIM when you need more (ByteSIM FAQ: not supported due to the anonymous nature of their eSIM products).

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).
