Refund policy

Superalink: Refunds only if the eSIM has not been activated and no data has been used; QRIS purchases must be requested within 7 days of purchase.

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

Superalink: Starts once the eSIM installs and connects to the local network at your destination — activation from home is possible, but Superalink recommends waiting until arrival; data isn't deducted until it connects there.

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

Superalink: On Unlimited plans, speed drops for the rest of the day once the daily high-speed allowance is used (no extra charge, resets the next day): 10GB/day to 5 Mbps, 5GB/day to 1 Mbps, 500MB-3GB/day to up to 384 Kbps.

WorldSIM: Not confirmed yet

Top-ups & rollover

Superalink: Enter your eSIM's ICCID on Superalink's Top Up page (My Voucher) to add data or extend — no reinstall needed, though it only becomes available once the current package's validity ends or its data runs out.

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.
