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.

esim0: Refund within 7 days of purchase if the eSIM cannot activate due to a fault on their side, advertised coverage is unavailable, the same plan was bought twice, or the QR code was not delivered within 24 hours. No refund once the eSIM has been activated or used, or for device incompatibility or changed travel plans.

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.

esim0: Validity starts at the first connection to the network (Terms §6); an unused eSIM stays installable for 180 days after purchase.

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.

esim0: Not confirmed yet

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).

esim0: Top-ups from the dashboard for eligible eSIMs only; a different destination or an expired plan needs a new eSIM.
