We have an upcoming trip to Japan. What WiFi hotspot or data plan have you had good luck with. Mostly major cities and train travel on the schedule.
Google fi - had LTE the whole time I was there, 3 yrs ago
I haven’t been back to Japan since smart phones, but I have to tell you that I love the T-Mobile international feature. I have been traveling for for about 16 months now; Ecuador, Mexico, Poland, Colombia, and Peru, and have found it to be good. I only use it for maps, texting, and VoIP calls. There are some websites that are light enough to load, but for anything heavier I use the internet in the places I am staying. I make sure to download the local maps to Google Maps when I am on a good signal. I have had problems with Google maps not wanting to do walking directions. When that happens I switch it to driving directions and be extra careful of where it is trying to send me.
Welcome to the forums!
I used this hotspot in Japan in late 2018 and it was great. I had it delivered to my hotel and it was wating for me when I checked in. On my way back, I dropped it off at a mailbox at the airport.
I crossed this wifi router and people are swearing by it. It lets you connect to hotspots, including ones with a captive portal. You can even have it setup a connection through a VPN so that that you can watch and do whatever you want without worry.
