During my business trip to Osaka, keeping up with urgent emails between conference meetings was critical for my work.

I never had to hunt for unreliable public Wi-Fi networks in crowded stations or cafes. For any professional traveling on a tight schedule, having continuous connection from the start is an absolute lifesaver.
