Refund policy

eSimHero: Full refund only while the eSIM is untouched (not installed, activated or used); requested from "My eSIMs" and processed immediately back to PayPal or the wallet. No partial refunds once activated.

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

eSimHero: The validity period starts at activation, i.e. when the eSIM first connects to a supported network in the coverage area; no manual activation step is needed.

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

eSimHero: Unlimited plans have a stated daily high-speed cap (e.g. 2GB/day), after which speed drops to 1 Mbps or 512 kbps until the next day; regular plans have no cap beyond operator-side traffic management.

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

eSimHero: Top-ups can be added to the existing eSIM where the destination supports it; some destinations require buying a new eSIM instead.

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.
