How do I insert the SIM card to my Lumia 925?

Switch the power off before inserting the SIM card.

  1. Turn the phone over so the back is facing you.
  2. Insert the SIM door key into the hole in the SIM card holder until it is released.
  3. Pull the holder open enough to allow SIM card to slide into position. Do not remove the SIM holder.
  4. Place the SIM card with the contacts facing upward into the holder.
  5. Push the holder back in until it locks into place.
  6. Press and hold Power key to switch on the phone.
