Record the SIM’s serial number on the
Installation Checklist (1).

SM does not recommend using SIM Cutters
to cut the SIM to the correct size.
The Nano SIM is to be inserted so that the
metal chip is visible (facing up). You must
match the cut corner on the SIM card to the
matching corner on the tray.
Once the SIM is inserted push the tray
closed. An audible click should sound when
the SIM tray is in the correct position.
The tray will be more difficult to close if the
SIM is inserted incorrectly. Forcing the SIM
Card Tray into the Controller may damage
the processor. DO NOT FORCE THE TRAY
CLOSED.
