Callback
You must apply to your local network operator for this fea-
ture. Inquire about the respective charges.
If you have activated callback because the party you called
was busy, you are automatically called back as soon as the
other party finishes his/her call.
If you are engaged in a call when callback takes place, you
are called again on completion of your call.

the time.
