How to set it up

I didn't really understand how to set it up, so I contacted them by email and they answered the phone and kindly explained it to me.
Normally, I would purchase a SIM card and use it, so I think I would be able to use it even after the 30-day usage period as long as I had some remaining balance, but this time it stopped after 7 days as per my contract.

Configuration Support

Previously, I paid 500 yen and received support for setting up the esim at the store (Haneda Airport Terminal 3), but is this no longer available? I have always borrowed a simple mobile phone and set up your esim 50G for 30 days on my SIM-free iPhone that I use overseas (in the US). This time, I purchased it exactly 58 days (not to exceed 60 days) before arriving in Japan, but when I receive the simple mobile phone, will you still provide support for setting up the esim? Of course, I don't mind paying for it. It may not be that difficult, but it's my first time setting it up myself, so I'm a little worried.
