Last year I traveled to Tokyo for a business trip and quickly realized how important it was to stay connected. Before leaving, I spent some time reading the Japan Phone Number: The Ultimate Guide
https://www.mobal.com/blog/living-in-japan/japan-phone-number/ because I wanted to understand how mobile services work in Japan. It turned out to be really useful. I also decided to get a Mobal Japan SIM Card, which made things much easier. From arranging meetings to navigating the city, having reliable mobile service saved me a lot of time and stress.
