"Strong signal even on Mount Fuji." 2-minute setup, auto-activated on landing at Narita. No more hunting for a SIM at the airport.

"Vietnamese support replied at 11 PM." I got stuck during first-time activation — pinged Zalo and the admin walked me through every step within 2 minutes.

"Half the price of airport SIMs, much easier." No queueing, no paperwork. Turn on the phone after landing and you're online. Great price, will keep using.
