Refund policy

eSIMFOX: Full refund if unactivated (no QR scanned, no data used) within 7 months of purchase, including device incompatibility/carrier-lock or a confirmed technical/coverage issue on their side. Processed in 5-10 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

eSIMFOX: Install before you travel, connect after you land -- validity starts when you activate mobile data at your destination, not at installation.

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

eSIMFOX: 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

eSIMFOX: Keep the same eSIM installed across trips and top it up for your next destination -- no new eSIM needed per country.

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.
