Short stopover in Osaka before heading to Australia. Bought this in advance and honestly it was hassle-free. Scanned the QR code at the airport and data started working within minutes.

We’re so glad to hear your eSIM worked seamlessly during your stopover in Osaka! Wishing you smooth travels and great connectivity all the way to Australia. Thanks for sharing your experience!

Installerede eSIM’en før afrejse og aktiverede den, da jeg landede i Tokyo. Forbindelsen var stabil hele ugen, også i Kyoto. Meget nem løsning til rejser.

Tak for din feedback! Dejligt at høre, at eSIM’en fungerede problemfrit under din tur til Tokyo og Kyoto. Vi er glade for, at det gjorde din rejse nemmere.
