Lenovo ThinkPad X1 User Manual page 25

The mobile broadband feature enables you to connect to the Internet from any location where cellular
service is available. Mobile broadband connections use 3G, 4G, or LTE cellular and mobile networks, just
as phones do. Mobile broadband connection is supported only on computer models with a wireless-WAN
card installed.
A nano-SIM card or an external mobile broadband device is required to connect to a mobile broadband
network.
Your computer also supports Bluetooth and NFC wireless communications. For more information, see
"Using NFC devices (for ThinkPad X1 Tablet)" on page 16 and "Using Bluetooth devices" on page 16.
To join a wireless network:
1. Tap the wireless-network icon in the Windows notification area. A list of available wireless networks is
displayed.
Note: If the Airplane mode control is on, or the Wi-Fi control or Mobile broadband control is off, the
list might not be displayed. Tap the corresponding control to display the list.
2. Tap a network to join it. For secured networks, enter the valid password when prompted.
To replace or install a nano-SIM card:
The nano-SIM card slot is behind the kickstand. Before you start, turn off the computer.
1. Push the nano-SIM card inward a little until you hear a click. The nano-SIM card ejects. Gently slide the
card out of the slot.
Note: If no nano-SIM card is installed in the slot, skip this step.
2. Install a new nano-SIM card into the slot with the metal contacts facing downward. Ensure that the new
nano-SIM card is installed in correct orientation.
