Motorola PF C25 mobile telephones feature global system for mobile
communications (GSM) air interface. The PF C25 also provides a wireless
application protocol (WAP) Internet browser. The PF C25 telephones incorporate a
new user interface (UI) for easier operation, allows short message service (SMS)
text messaging, and includes personal information manager (PIM) functionality. It
is a dual-band phone that allows roaming within the GSM 900 MHz and digital
cellular system (DCS) 1800 MHz bands. PFC25 telephones support SMS in addition
to traditional circuit switched transport technologies.
PF C25 telephones are made of a polycarbonate plastic. The display and speaker,
as well as the keypad, transceiver printed circuit board (PCB), microphone, external
accessory connector, volume buttons, power button, and voice button, are contained
within the flat form-factor housing. The phone accepts both 3V and 5V mini
subscriber identity module (SIM) cards which fit into the SIM holder underneath
the battery. The antenna is a fixed stub type antenna.
The PF C25 telephones use advanced, self-contained, sealed, custom integrated
