To install:

  • Install the SIM card into the SIM card holder with the contacts facing out and the card notch facing up.


  • Close the SIM card holder and slide down to lock into place. Ensure that the SIM card is fully inserted and lying flat. Also ensure that the end of the card is not laying on top of the SIM card tab.
