Ensure that:
• Your tablet is not in Airplane mode.
• The nano-SIM card is valid and workable if you are using a mobile network (3G or 4G).
• You are within the network service range and the signal strength is good.
• If a USB 3.0 device is attached to your tablet, the USB 3.0 device might influence the
wireless WAN connection. Detach the USB 3.0 device from your tablet to resolve
the problem.
