Recommendations for kid-friendly mobile options in Shirakawa-go?

Hey everyone! I'm a bit nervous about traveling to Shirakawa-go with my young kids this November. I want to make sure we stay connected during our trip, especially for safety and to keep them entertained. Are there any family-friendly SIM card or pocket WiFi options that work well in the area? I've heard the autumn leaves are stunning, but I'm also a bit worried about internet access in a rural place like Shirakawa-go. Any advice on reliable data plans or mobile apps for families traveling with children? Thanks in advance for any tips or reassurance!
