Phonecell® SX4D
for GSM 900 or GSM 1800


Fixed Wireless
Terminal Providing

All the features and functionality of a wireline telephone - without the wires. The Phonecell® SX4D Desktop Phones for GSM 900 or GSM 1800 are digital wireless telephones that incorporate fixed wireless technology in full-featured touch-tone phones. Rather than connect to a traditional landline, the SX4D Desktop Phones connect wirelessly to existing 900 MHz
and 1800 MHz GSM cellular networks. The SX4D Desktop Phone operates just like an ordinary wireline phone. The user picks up the handset, hears a dial tone, enters the phone number on the touch-tone keypad and waits for a connection. There is no SEND key. The Desktop Phone includes common wireline phone features such as caller ID, call waiting, 3-way calling, redial and voice mail with visible and audible indicators, which can be accessed with a single key. The Phonecell SX4D
Desktop Phones for GSM 900 and GSM 1800 are the ideal solution for today’s wireless communication needs.
