Refund policy

Bcengi: If your device doesn't support eSIM, a full refund is offered as long as the eSIM was never activated.

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.

Validity starts

Bcengi: Pay-as-you-go pricing -- no activation charge, you only pay for the data you actually use.

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.

Fair-use limit

Bcengi: Not confirmed yet

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.

Top-ups & rollover

Bcengi: Balance auto-refills automatically; you can also top up manually anytime through the online portal.

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).
