Japanese eSIM Card｜KDDI, SoftBank 5G Daily/Total eSIM

In my environment, KDDI's Band 41 and 5G (NR/NSA)-like indications were also displayed. The antenna pictogram was almost at maximum, and I was able to use the signal without any complaints. Although it is not an official specification, after various experiments, it seems that after activating the SIM and setting the APN, if the roaming setting is enabled, it roams on the Softbank line (the antenna pictogram also has an R for roaming, and the carrier name is Softbank), and if not, it uses the KDDI line (the antenna pictogram is normal, the signal used is KDDI, and the carrier name is China Mobile). In either case, the signal strength and usability did not change. In addition, the capacity and communication period are firmly mechanically controlled, and it can be used properly during the usage period, and after the usage period, the SIM cannot search for networks and is properly out of range. (There was no effect on the SIM I usually use) In this way, the operation seems to be quite reliable. Overall, since it has to go through an overseas line (or maybe I was just unlucky at the time), the connection speed is slow, so if you want to watch videos in high quality, you might need to be creative. However, the speed was fast enough to properly launch the chat app and send messages, so that was good.

This was the first time I received a message that my remaining data was low on my carrier (*_*) I had a 3-day trip, so instead of increasing the amount of data from my carrier, I used eSiM to get by, like when I go abroad (^-^)
