The speed of the 4G and 5G signals is very good. It works without any interruptions. If you try using eSim, you will find it easy, convenient, and economical. You do not need to buy or subscribe to expensive mobile phone roaming packages. You also need to register your identity. We recommend using eSim to complete every trip.
Traveling to Narita Airport was easy and convenient, with no transfers required. It's much cheaper than buying tickets at a Japanese station, and the process is also simple, so I think I'll continue to use it.
