Refund policy

InternationalSIM: 14-day money-back guarantee: full refund if the eSIM QR code has not been scanned or activated, processed to the original payment method in 3–5 business days.

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

InternationalSIM: Smartstart: plans activate automatically on arrival in a covered destination, with the validity period starting then, not at purchase; unactivated plans expire automatically 6 months after 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

InternationalSIM: Data services are subject to Fair Use Policies set by the local network carrier per InternationalSIM's terms, but no specific data threshold or throttled speed is disclosed.

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

InternationalSIM: Existing eSIMs and SIM cards can be recharged with more data through the InternationalSIM customer portal without needing a new eSIM.

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

InternationalSIM: A new eSIM would be required.

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

InternationalSIM: All InternationalSIM product listings and checkout prices are calculated and charged in EUR (€), including VAT.

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.
