Land connected. No SIM swap, no bill shock.
Saily is a travel eSIM built by the NordVPN team: buy data in the app before you fly and connect automatically on landing. No airport SIM queues, no SIM ejector pins, no monster roaming bills.

Four travel-data nightmares
One bad trip is all it takes
Airport SIM queues
Fresh off a long-haul flight and stuck at a kiosk for half an hour, negotiating in a language you don't speak at tourist prices.
Roaming bill shock
Forget to switch off data roaming once and come home to a phone bill that costs more than the hotel.
Losing your own number
Pull your physical SIM and banking SMS codes, calls and notifications all go missing for the whole trip.
Stranded offline
Ride-hailing, maps, translation — everything needs data, and the moment you land with no signal is the worst.
Three steps to land connected
Easy even for first-time eSIM users
Download the Saily app
Free on the App Store / Google Play; iPhone XS and later plus most recent Androids support eSIM — the app checks compatibility for you.
Pick a plan, enter KUKU
Choose your destination and data plan, enter promo code KUKU at checkout for an instant discount. No physical card to ship.
Connect on landing
Install the eSIM before you fly; data works the moment you land, while your home SIM keeps receiving SMS as usual.
Why Saily
More than travel data — it ships with a security layer
200+ destinations
Japan, Korea, Southeast Asia, Europe, the Americas and beyond — one app, with automatic switching on multi-country trips.
Keep your number
The eSIM handles data only; your physical SIM stays in, so calls and SMS (including bank OTPs) keep arriving.
Built-in protection
Ad blocker, web protection and virtual location built into the app — an extra layer on airport and hotel Wi-Fi.
By the NordVPN team
A Nord Security product with real security pedigree and global infrastructure — not a no-name SIM reseller.
24/7 live support
Real humans around the clock, so a mid-trip issue never waits for another time zone's office hours.
Top up anytime
Running low? Add data right in the app — no reinstalling the eSIM, no queuing for another card.
My hands-on verdict
Two things I dread when traveling: landing with no data, and the roaming bill afterwards. With Saily the routine became "buy a plan in the app five minutes before departure, land, phone just works" — the airport SIM hunt is simply gone from my trips.
The surprise win is the security layer: on airport and hotel Wi-Fi, the built-in web protection and ad blocker quietly filter out the sketchy stuff. Regular travel SIMs have nothing like this — it's very much the NordVPN DNA showing.
