29.4 Managing UMTS/3G Network
Connections
Universal Mobile Telecommunications System (UMTS), also known as 3G, is a cell
phone technology which can offer several multimedia services such as browsing the
Web or sending and receiving messages. UMTS cards that are available as PCMCIA
cards or Express Cards can be connected to your computer or laptop, and in combination
with a SIM (Subscriber Identity Module) card, use the UMTS network to connect your
machine with an Internet provider.
To use the UMTS module included in SUSE Linux Enterprise®, you need to install
the umtsmon package that is not installed by default. It contains the software to control
your UMTS (or GPRS/EDGE) card. With the UMTSmon application, you can then
control the network connection. After the network connection has been established, use
a Web browser of your choice to surf the Internet.
After you have installed the umtsmon package and have connected your UMTS card
to the computer, make sure that the smpppd service is running: Start YaST, select System
> System Services (Runlevel) and check the status of smpppd. If smpppd is not enabled
yet, click Enable. After you have received a confirmation message, leave the module
with Finish.
Now start UMTSmon from the main menu or press Alt + F2 and enter umtsmon. You
are usually prompted to enter your SIM card's PIN before the UMTSmon main window
appears.
