My recent business trip to Japan was quite intense. Lots of meetings, traveling between cities, and almost no free time. In such a situation, it's especially important for everyday issues to take care of themselves and not require unnecessary attention. Before leaving, I researched various connectivity options and realized it was better to decide on the internet access type in advance. I decided to order a Mobal Japan Pocket WiFi
