Refund policy

shibaSIM: Contact support within 7 days of purchase if a provider-side technical fault prevents activation, or for a mistaken plan whose QR code has not been installed or used. Approved refunds return to the original payment method in 5–10 business days. No refund once activated or used.

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

shibaSIM: Validity starts when the eSIM first connects to a network at the destination, unless the plan description states otherwise.

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

shibaSIM: Daily plans: a fixed amount of high-speed data per day (0.5GB to 5GB depending on the plan), then data continues at reduced speed.

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

shibaSIM: Not offered: no self-service top-ups; customers buy a new plan 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.

Lost device / reinstalling

shibaSIM: 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

shibaSIM: International checkout charges USD; Vietnamese checkout charges VND.

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.
