Placing the SIM card in the Internal Modem
First you’ll have to eject the
holder tray
from the SIM card holder by pressing in the
yellow button
on the front panel of the SEC unit:
Then you need to place the SIM card in the holder tray in the correct way (note the slanted edge on
the SIM card).
Reinsert the tray into the slot, facing in the same way as it was when you have taken it out (for
orientation reference, see the picture below).
Don’t use too much force while reinserting; if the card holder doesn’t click in to place easily, that
means the orientation isn’t correct.
The SIM card holder built into the unit looks like the following, with the holder tray taken out:
Important note:
Only insert and remove the SIM card when the unit is turned off. Otherwise you can
damage the SIM and the modem.
Troubleshooting:
If you’ve inserted the SIM to the modem before turning off the unit, then the
modem won’t recognize it. You need to power off the unit and then back on.
