ID verification

ByteSim: Not confirmed yet

InternationalSIM: Not required

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.

InternationalSIM: 14-day money-back guarantee: full refund if the eSIM QR code has not been scanned or activated, processed to the original payment method in 3–5 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.

InternationalSIM: Smartstart: plans activate automatically on arrival in a covered destination, with the validity period starting then, not at purchase; unactivated plans expire automatically 6 months 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.

InternationalSIM: Data services are subject to Fair Use Policies set by the local network carrier per InternationalSIM's terms, but no specific data threshold or throttled speed is disclosed.

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).

InternationalSIM: Existing eSIMs and SIM cards can be recharged with more data through the InternationalSIM customer portal without needing a new eSIM.
