AUStress-Free Travel with Instant QR code from app
I bought the Japan eSIM last minute and the QR code arrived immediately within the king sims app. Installation was just scan and go and pretty easy to set up. The SoftBank connection gave me reliable 4G while hopping between Kyoto’s Fushimi Inari and Osaka’s food alleys, so Google Maps and local train apps worked flawlessly since I needed data. I used WhatsApp for quick check-ins and even completed a couple of online banking transactions without trouble, which made travel feel much safer. Customer support replied quickly when I had a small billing question and topping up later was straightforward 🙌
