During my visit back home, I experienced IIJmio OFF-time communication restrictions and thought “not being able to buy additional coupons is a lost opportunity,” so I’ll introduce this.

OFF-Time Communication Restrictions Make Everything Impossible

When IIJmio has OFF-time communication restrictions, you only get a few kbps of communication speed, so you really can’t do anything. Before you can’t do anything, buy additional coupons.

• クーポンはどこで購入できますか? | IIJmio

In my case, my wife’s IIJmio bundle coupon had some remaining, so I had her tether for me and managed to buy just 100 MB of additional coupons. 216 yen expense?

• テザリングは可能ですか? | IIJmio

Service Improvement Proposal for IIJmio

I think it would be good to prepare a dedicated app that can purchase additional coupons even during OFF-time communication restrictions to avoid lost opportunities.

That’s all from the Gemba where I almost died because I couldn’t buy additional coupons during IIJmio OFF-time communication restrictions.
