Excellent e-SIM, flew to Japan, the network is stable and fast, sometimes even faster than the hotel Wi-Fi. The price is unbeatable. I recommend it!

I disabled airplane mode before getting off the plane, and after connecting the SIM card, it connected smoothly after a short while. There were no complicated settings, and the signal strength was always stable, which was very helpful.

The connection was good, and since I installed it in advance, I was able to use it immediately upon arriving in Guam. I was assigned a local number, so I was able to make calls conveniently while there.
