In order to use your sim port, your 8440P, must have come installed with a Wireless Wide Area Network(WWAN) card. It is usually accompanied by software from a specific provider(e.g Verizon, AT&T, QWEST) or if you have an mobile account with a provider, a username and password may be required to connect to your account. You can read the documents below provided by HP to get a better understanding of the process.
