Can I connect to FLET'S ADSL Entry and another connection service with one Asahi Net User ID?
To Asahi Net's dial-up access point, yes.
To one of Asahi Net's other always-on broadband services, no.
By dial-up access point we mean Asahi Net's All-Japan Access Point.
By always-on services we mean ADSL services (FLET'S ADSL, Neo-Discount ADSL), Fiber-optic services (FTTH with FLET'S, B FLET'S, etc.), the FLET'S Spot services, etc. If you want to connect to FLET'S ADSL Entry and to another always-on service at the same time, consider signing up for another Asahi Net User ID.
