Refund policy

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

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.

ZetSIM: Validity starts when the eSIM first connects to a local network at the destination, not at purchase.

ZetSIM: Unlimited plans: 2GB of high-speed data per day, then 256 kbps; the daily allowance resets every 24 hours from first connection.

Top-ups & rollover

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.

ZetSIM: Add a new plan to the eSIM you already installed: no new QR code, no reinstall.
