But you're right I apologize:
The aquos sense3 is device supports 7 Bands. Compare that to most other android devices that have upwards of 20. B1,B2,B4,B8,B5,B9, B28. Personally I don't even understand how as a Japanese you're supposed to travel with these devices. The first device I saw with this kind of connectivity internationally was the Poco F1. Which was a flagship SoC for 300 bucks.
