Figure 4-1 Accessing the SIM card on the bottom of the module
It’s easiest to insert the SIM card if you set the module on its side
(Figure 4-2) and push the card into its slot as shown. To remove
the card from its slot, push on it and it will pop out enough that
you can grasp the end and pull it out.
Figure 4-2 Inserting the SIM card into the module
After inserting the card, slide the internal lock (next to the slot
for the SIM card) to the locked position, to make sure the SIM
card stays in place. Then reinstall the metal cover on the bottom
of the module.
