After staying in Kyoto for two months, it’s clear that the public Kyoto WiFi, and the one offered in public cafes and so on is not enough for a foreigner, as we’re always on the go. Pocket WiFi seems really popular and expensive, but if you have an extra phone, you might as well just pick up a surf SIM-card with 2GB data preloaded and valid for three months. If staying longer in Japan it’s much cheaper than a pocket WiFi, depending on your use case of course.
I bough mine at Bic Camera (When leaving Kyoto station main entrance, just turn left directly, walk a hundred meters and you’ll see the building), but I would be surprised if Yodobashi didn’t have them.
They look like this. The setup is supersimple, and instructions in English are included.
