I always use it when I come back to Japan during my trip around the world. It's easy to connect to the internet, so I can use mobile payments like Mobile Suica and Rakuten Pay.★

I have previously purchased this type of eSIM before, the setup process is straightforward, after the phone connects you need to enable roaming on this eSIM. You will see the IP address is from Hong Kong. There's a bit of latency but everything else works normal.★
