Chapter 3. Wireless networks and devices

Your tablet can connect to a variety of networks and devices, including mobile networks (2G or 3G), Wi-Fi
data networks, and Bluetooth devices.
Note: Some tablet models can connect to both mobile networks (2G or 3G) and Wi-Fi networks, while others
can connect to Wi-Fi networks only. If your tablet supports Wi-Fi connection only, the information related
to mobile networks does not apply to your tablet.

Installing the SIM card

If your tablet supports mobile network connection, it might require a SIM card to connect to a mobile
network. Depending on the country of delivery, the SIM card might be shipped with your tablet or you need
to purchase one from the service carrier.
Attention: When installing or removing the SIM card, do not touch the SIM card metal connectors. As
a precaution, always hold your tablet in your hand before you install or remove the SIM card to avoid
electrostatic discharges.
To install a SIM card, do the following:
1. Turn off the tablet by pressing the power button for a few seconds, and then touch OK from the Power
off menu.
2. Open the SIM card slot cover and locate the SIM card slot. To locate the SIM card slot, see "Tablet
layout" on page 1.
3. Hold the SIM card with the metal contacts facing down, and then insert it firmly into the SIM card slot
until you hear a click.
4. Close the SIM card slot cover and restart your tablet.
To remove the SIM card, after you turn off the tablet, push the SIM card inward until you hear a click. The
SIM card ejects. Gently slide the SIM card out of the slot.

Determining which mobile network you are using

For some networks, you can check the network name to see which mobile network you are using.
