# Before Using the Wireless WAN
<Wireless WAN equipped models>

A Wide Area Network (WAN) is a widespread communications network that makes it possible to connect local computer networks in remote locations together, and it is often available with communication facilities provided by carriers, such as telecom operators.
Using the wireless WAN (WWAN) allows your VAIO computer to connect to the Internet through the wireless network wherever there is the mobile phone coverage.
Depending on the carrier you are using, you may need to insert a SIM card into the SIM card holder or slot on the computer to use the wireless WAN function. Your SIM card is contained within a base plate, about the size of a credit card.
Note

- The wireless WAN may not be available in some countries and regions.

Hint

- Depending on your country and model, you might receive an offer from the VAIO selected carrier. In that case the SIM card is either in the carrier’s SIM pack inside the carton box or already inserted in the SIM card holder or slot. If the SIM card is not provided with your VAIO computer, you can purchase one from your preferred carrier.

## To insert a SIM card

1. Turn off your VAIO computer.

1. Open the SIM card cover on the bottom of your VAIO computer.

1. Slide the SIM card holder (1) in the direction of the arrow and then open the holder.

1. Remove the SIM card by pushing it out from the base plate.
