Windows does not recognize the new network, follow the same procedure you used initially to 
connect to your WLAN. 
Using HP Mobile Broadband (select models only) 
HP Mobile Broadband enables your computer to use wireless wide area networks (WWANs) to 
access the Internet from more places and over larger areas than it can by using WLANs. Using HP 
Mobile Broadband requires a network service provider, which in most cases is a mobile phone 
network provider. 
When used with mobile network provider service, HP Mobile Broadband gives you the freedom to 
stay connected to the Internet, send e-mail, or connect to your corporate network whether you are on 
the road or outside the range of Wi-Fi hotspots. 
NOTE:  You may need the HP Mobile Broadband Module serial number to activate mobile 
broadband service. Refer to the Getting Started guide for the location of the serial number. 
Some mobile network service providers require the use of a subscriber identity module (SIM). A SIM 
contains basic information about you or your computer, such as a personal identification number 
(PIN), as well as network information. Some computers include a preinstalled SIM. If the SIM is not 
preinstalled, it may be included with the HP Mobile Broadband information provided with your 
computer, or it may be provided separately by the mobile network service provider. 
For information on inserting and removing the SIM, refer to Inserting a SIM on page 7 and 
Removing a SIM on page 8. 
For information on HP Mobile Broadband and how to activate service with a preferred mobile network 
service provider, refer to the HP Mobile Broadband information included with your computer. For 
additional information, see the HP Web site at http://www.hp.com/go/mobilebroadband (U.S. only). 
Inserting a SIM 
NOTE:  To identify the SIM slot location, refer to the Getting Started guide. 
1.  Shut down the computer. If you are not sure whether the computer is off or in Hibernation, turn 
the computer on by pressing the power button. Then shut down the computer through the 
operating system. 
2.  Close the display. 
3.  Disconnect all external devices connected to the computer. 
4.  Unplug the power cord from the AC outlet. 
5.  Remove the battery. 
6.  Insert the SIM into the SIM slot, and gently press the SIM into the slot until it is firmly seated. 
CAUTION:  When
 inserting a SIM, position the card to match the icon next to the SIM slot on 
the computer. If a SIM is inserted incorrectly, it could damage the SIM and the SIM connector. 
To reduce the risk of damage to the connector, use minimal force when inserting a SIM. 
7.  Replace the battery. 
NOTE:  HP Mobile
 Broadband is disabled if the battery is not replaced.
