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.

TooSim: Refunds are conditional -- if you haven't scanned the QR code or used the data plan, you may be eligible for a refund.

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.

TooSim: Not confirmed yet

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.

TooSim: 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.
