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 (called a
mobile network operator ), which in most cases
is a mobile phone network operator. Coverage for HP Mobile Broadband is similar to mobile phone voice
coverage.
When used with mobile network operator 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.
HP supports the following technologies:
●
HSPA (High Speed Packet Access), which provides access to networks based on the Global
System for Mobile Communications (GSM) telecommunications standard.
●
EV-DO (Evolution Data Optimized), which provides access to networks based on the code division
multiple access (CDMA) telecommunications standard.
You may need the HP Mobile Broadband Module serial number to activate mobile broadband service.
The serial number is printed on a label inside the battery bay of your computer.
Some mobile network operators require the use of a subscriber identity module (SIM). A SIM contains
basic information about you, such as a PIN (personal identification number), as well as network
information. Some computers include a SIM that is preinstalled in the battery bay. If the SIM is not
preinstalled, it may be provided in the HP Mobile Broadband information provided with your computer
or the mobile network operator may provide it separately from the computer.
For information on inserting and removing the SIM, refer to the “Inserting a SIM” and “Removing a SIM”
sections in this chapter.
For information on HP Mobile Broadband and how to activate service with a preferred mobile network
operator, refer to the mobile broadband information included with your computer. For additional
information, see the HP Web site at

Inserting a SIM
CAUTION: When inserting a SIM, position the card with the slanted corner as shown in the illustration.
If a SIM is inserted backwards or upside down, the battery may not snap into place properly and could
damage the SIM and the SIM connector.
To prevent damage to the connectors, use minimal force when inserting a SIM.
To insert a SIM:
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. Turn the computer upside down on a flat surface, with the battery bay toward you.
