Using C-mail
C-mail is a service that makes it possible to exchange
messages between two au cell phones that support c-mail.
A c-mail message can contain up to 50 double-byte (or 100
single-byte) characters.
Subscribers in the Kanto and Chubu areas do not need a
separate subscription to use c-mail. For subscribers located
outside of these areas, a separate subscription is required.
C-mail Safe Block Function
C-mail safe block function is a function that allows you to reject
to receive c-mail messages that include accessing URL
(http://△△△, https://△△△) or phone numbers in the c-mail
message text.
C-mail safe block function is valid by default. You can cancel the
setting if you want to receive c-mail messages that include
accessing URL or phone numbers in the message text.
