You should follow these step to install the sim.

• If the device does not have a SIM, the signal strength icon will turn red.
• Insert / Remove SIM Card and Battery: Use the latch to remove the back cover.
• Remove the battery by gently pulling up from the bottom mark.
• Slide the Nano SIM into the SIM slot with the metal contacts facing down.
