Superalink eSIM review

4.6

The short answer. Superalink sells prepaid travel eSIM plans in 146 countries, and its cheapest rate today is $0.66 per GB. Its median rate of $1.11 per GB is about 61% below the $2.83 median across every plan we track. On price it is a reasonable default, and the country page for your destination will still show you whether someone there beats it.

Have we checked these prices?

100% of Superalink's plans on this site were checked against Superalink's own shop on 16 October 2026, one country page at a time. We confirm the product is on sale and that the price is the one they charge, and we take their price over ours whenever the two disagree.

A feed is not a shop. Feeds can list products that are not on sale, describe them differently, or carry a stale price, so a price nobody has checked again is only a number we copied.

Superalink did not pay for this review or this rating. The rating is computed from live catalogue data and cannot be bought. If you buy through a link on this page we may earn a commission, and the price you pay stays exactly the same.

About Superalink

Who is Superalink?

Superalink is the global brand of Gadget Korea, a Seoul startup that raised a 4.6 million dollar Series A in January 2025 and became the first startup admitted as a full GSMA member through its Singapore entity, GADGET SG. Launched in February 2024, it focuses on Asia with 150+ destinations and a daily unlimited pricing model: you pick a full speed quota per day, from 500MB to 5GB, and pay per day of travel.

Everything is web based with no app: QR delivery by email, a web dashboard for usage, and 24/7 support over WhatsApp chat that its Trustpilot reviews consistently praise for speed. Every plan carries free Supera Care compensation if connectivity fails, and Japan buyers get extras like Don Quijote shopping coupons and a GO Taxi discount.

The daily quota model needs reading before you buy: after the quota, 5GB plans throttle to 1Mbps and smaller tiers to 384kbps, hotspot is capped at 2GB a day, and the daily reset runs 24 hours from your first connection rather than at midnight. In our tables its per day pricing is very competitive for short Asian trips.

How do I install a Superalink eSIM?

QR code by email, no app. Install 2 to 3 hours before departure; activates when the device attaches to a local network with data roaming on. Buy the plan online, scan the QR code on wifi before you fly, and leave the new line switched off until you land. Then turn on data roaming for the Superalink line and give it a minute to attach to a network. If the code will not install, our guide to eSIM QR code errors covers every message a phone can show.
