Excellent connectivity
Fantastic service! I got the SIM gor my holiday for 3 weeks, and I survived with 20GB. It sometimes didn't work in crowded areas, but surprisingly it worked in very small villages and by the beach.
I spend a 1/1/2 week at Osaka and Kyoto, to play the Pokemon Go Festival 2025 and it requires stable 5G connectivity, 98% of the time it delivers the connectivity I need, during the event and It was a worth it, when I come to Japan again for another Pokemon Go event, definitely will use this service again. Things to improve some areas in Namba Ward, around den den town, it throttles down a bit, specially with in shopping areas, and some part of the expo 70 commerative park near the lake the speed is sometimes throttling down to 4G instead of 5G, this is my 2% definitely a recommended one
Data was usable for the whole trip! Thank you 🥰
