Refund policy

CloudOn: Full refund only if never installed/activated, requested within 30 days of purchase. Once activated: generally non-refundable, except a partial refund for unused data if usage is minor AND a verified network/technical failure prevented service. Discount-code purchases are non-refundable once activated. DTAC Thailand 50GB/10-day and Unlimited plans follow a separate, per-plan refund policy.

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

CloudOn: Validity starts on first network connection, not at purchase or installation - a 7-day plan installed a week early still gives the full 7 days once first connected.

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

CloudOn: Unlimited plans include a fair-use high-speed data allowance before speeds are reduced for the rest of the validity period - the exact threshold and reduced speed vary by plan and are stated on that plans own page.

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

CloudOn: Supported - top-ups add to the existing eSIM directly from the CloudOn account, no new QR code or reinstall needed.

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.
