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.

ZetSIM: An eSIM that has not been activated and whose plan is still valid is refunded in full, with no fee, as refund coins (store credit in the same currency, never expires, not withdrawable as cash). No refund once activated or for unused data.

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.

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

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.

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

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.

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