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.

Cellesim: Refunds only for technical failures caused by Cellesim that support can't resolve; locked/incompatible phones, user error (e.g. deleting the eSIM), wrong-device installs and change of mind after delivery are non-refundable.

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.

Cellesim: The validity countdown does not start at install - it begins only when the eSIM first connects to the network at your destination, so installing early does not waste days.

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.

Cellesim: Carriers throttle the connection after the high-speed cap (often 5-20GB depending on tier); Plus/Premium tiers keep full speed longer.

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).

Cellesim: Where a top-up is offered for your eSIM, add data from your Cellesim account or app to the same eSIM profile without reinstalling; if none is available you need to buy a new plan.
