Only with selected models, your may not have WWAN module. Please check the WLAN/WWAN compartment to see anything there:

Open the compartment in the picture Quang Do posted above. If you have antennas in there, but no WWAN card, then you need this WWAN card from HP: You will also need the 2 small screws that fasten the card to the motherboard. If you don't have antennas in the compartment, then you probably cannot install one.
HSPA EV-DO WWAN module Part # 531993-001 This part # does not include the 2 screws.
Below is the link to order from the US website. If you don't live in the US, contact HP support for your country and order the part from them. It isn't cheap! $253 USD.
As for the screws, you need two Phillips PM2.5×6.0 screws.
