To consider
GSM networks operate in the 850/900/1800/1900 Mhz bands.
GSM modems are typically either dual or quad band.
Note: You must acquire a dual modem that operates at the correct frequency, or purchase a
quad band modem.
European markets typically use 900/1800 Mhz capable devices.
The U.S. and Canada use 850/1900 Mhz capable devices.
Troubleshooting SMS Modems
If an SMS modem is not working as expected, verify that the communications port (COM port)
to which the modem is attached is configured to use settings supported by the modem.
1 In the Windows Control Panel, double-click Device Manager. The Device Manager
appears.
2 Expand Ports.
3 Double-click the communications port used by the SMS modem. The Communications
Port Properties dialog appears.
4 Select the Port Settings tab.
5 Using the documentation provided by the modem manufacturer, verify that the port
settings listed are supported by the modem. If the listed settings are not supported,
make any necessary changes.
Note: If you are using the MultiModem® GPRS external wireless modem, model MTCBA-G-F2,
set Flow Control to Hardware.
6 Click OK to save changes.
Using line feeds and carriage returns to correct SMS modem issues
Some SMS Direct enabled phones do not work correctly with SMS Direct Actions because
new line characters are not always handled properly. This issue may be corrected by adding
the following new registry key entry:
HKEY_LOCAL_MACHINE\SOFTWARE\Ipswitch\Network Monitor\Whatsup plugins\Actions\ActSmsDirect\NewLine
In the Value data box, enter a combination of a carriage return (\r) and/or line feed (\n)
command. For example enter one of the following:
newline \r\n (recommended)
newline \r
newline \n
