Refund policy

Billion Connect: Refundable before activation; once activated/used, refund rights end; third-party partner purchases are excluded from refunds.

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

Billion Connect: Most plans start when the eSIM first connects to a supported network at your destination (some start on installation, as the product page states); activate within 90 days of purchase; a day = 24 hours from activation.

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

Billion Connect: Set per plan on the product page: most plans drop to a reduced speed (typically 128–384 kbps) after the high-speed allowance, daily or total, instead of cutting off; a few plans stop at the 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.

Top-ups & rollover

Billion Connect: Standard eSIMs can't be topped up; buy a new plan when data runs out. eSIM Air supports top-ups anytime without reinstalling.

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).
