Using Service Dialing
Dial preprogrammed numbers stored on your
SIM card. Your service provider may program
your SIM card with numbers for services such
as taxi companies, restaurants, and hospitals.
Using DTMF Tones
You can send numbers to the network as Dual Tone
Multi-Frequency (DTMF) tones during a call. Use DTMF
tones to communicate with automated systems that
require you to submit a PIN code or credit card number.
Activating DTMF Tones
You can set DTMF tones to
Long
,
Short
, or
Off
:
Short
sends a short fixed-duration tone for each keypress.
Long
sends each tone for as long as you press the key.
Short DTMF tones work with most automated systems.
Some systems (such as home answering machines) may
require long tones for proper activation.
