Can I use "Omatome Seikyu Service (combined billing method)" even if I'm using NTT docomo's 2 in 1 service?

You can use "Omatome Seikyu Service (combined billing method)" if you designate either of phone numbers of the service "2 in 1" as your main line of "Omatome Seikyu Service."
If you want to use "Omatome Seikyu Service" for both of lines of the service "2 in 1," please apply for single billing service for charges of the two lines at NTT docomo in advance.
