IIJmio Data Option (20GB/30GB) was convenient for temporary remote work tethering, so I’ll introduce it.
Before Data Option, I Covered with Plan Changes
I didn’t know about the existence of IIJmio Data Option until recently, but when I researched, it seems the service started in June 2017.
Until learning about this service, I would change plans by the month before remote work was scheduled to get by. However, the problem with plan changes was that if you didn’t change plans by the previous month, you couldn’t increase available data during the current month.
I normally use the Minimum Start Plan (3GB), but I would switch to the Family Share Plan (10GB) in the month before planning to use IIJmio line (BIC SIM) tethering for remote work. However, I sometimes forgot to change plans, which was very troublesome.
Caution: Data Option Charges Monthly Fees Unless Canceled
Needless to say, when you contract a Data Option, monthly fees are charged until you cancel it yourself.
If you know you won’t need the Data Option next month, I recommend canceling it before the month changes.
That’s all from the Gemba, where I occasionally use tethering for remote work.
