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.

WorldSIM: Unused, unopened items can be returned within 14 days for a full refund minus postage; faulty products are exchanged or refunded after testing confirms the fault.

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.

WorldSIM: Lifetime validity on the airtime credit itself, as long as you top up at least once within the airtime validity period (30/90/180/365 days depending on the bundle bought) to keep it active.

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.

WorldSIM: 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).

WorldSIM: Pay-as-you-go: top up airtime credit any time it runs low (via account or short-code), then convert credit into data/call/SMS bundles for any destination — no new eSIM or QR scan needed.
