Refund policy

eSIM4: 30-day refund window from purchase if the eSIM has not been activated; also refundable/exchangeable if it can't be installed due to a technical problem on eSIM4's side. Once installed, considered used and non-refundable.

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

eSIM4: The validity period starts when the eSIM connects to any supported network(s), not at purchase.

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

eSIM4: Not confirmed yet

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

eSIM4: Set per plan — most plan listings state "Rechargeable online with no expiry" (see each plan's own note); not every plan mentions rechargeability.

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

eSIM4: An eSIM can only be installed once — reinstalling shows "no longer valid/available"; eSIMs cannot be reinstalled or regenerated once removed.

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

eSIM4: Billed in USD (native USD pricing, Stripe checkout).

Superalink: USD is the primary payment currency; other currencies may be accepted depending on availability and payment method, with the transaction currency set at the time of purchase.
