Refund policy

co:sim: Uninstalled eSIMs refunded unconditionally within 30 days of purchase; once installed, refundable only for a technical issue on co:sim's side.

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.

Validity starts

co:sim: Not confirmed yet

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.

Fair-use limit

co:sim: Daily plans throttle to a lower speed (e.g. 512Kbps) once the daily limit is reached; total-data plans simply stop once depleted.

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.

Top-ups & rollover

co:sim: Top up your balance anytime on the website -- instant, choose from various amounts; PAYG deducts per MB, data packages from $0.90/GB.

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.

Lost device / reinstalling

co:sim: Not confirmed yet

Superalink: A deleted eSIM can be reactivated on the same device, but cannot be reissued for a different device, per Superalink's own FAQ.

Billing currency

co:sim: Not confirmed yet
