I already thought it was a great deal when I bought it at the travel expo, but it was even cheaper online, down to just 1 yuan. It's simple and easy to use, and the reception was consistently good and smooth. I've never used KDDI before, but I'll definitely consider buying and using it next time.

This sim card is very affordable! Just encountered a special offer (sim card due date is November 11), five dollars a piece, 4 days total 3G. Bought two for a week trip, the whole process received very well, no disconnection, very fast network speed. If keep having this offer, I really want to repurchase!

It's rare to find physical cards that cost only a few dollars and arrive smoothly in Shikoku a few days later.
