If your computer supports the wireless wide area network (WAN) feature, a micro Subscriber Identification
Module (SIM) card might be required to establish wireless WAN connections. Depending on the country or
region of delivery, a micro SIM card might be already installed in the micro-SIM-card tray.
Note: Ensure that you use a micro SIM card. Do no use a standard-sized SIM card. The standard-sized
SIM card is not compatible.
To install or replace the micro SIM card, see "Installing or replacing the micro SIM card" on page 78.
