Procedure
NO TE
● If you prepared a WLAN-FE Smart Dongle or 4G Smart Dongle configured with a SIM
card, skip this step.
● If you prepared a Smart Dongle without a SIM card, you need to prepare a standard SIM
card (size: 25 mm x 15 mm) with the capacity greater than or equal to 64 KB.
● When installing the SIM card, determine its installation direction based on the silk
screen and arrow on the card slot.
● When being pressed into place, the SIM card will be locked, which means that the card
is installed correctly.
● To remove the SIM card, push it inwards. Then the SIM card springs out automatically.
● When reinstalling the WLAN-FE Smart Dongle or 4G Smart Dongle, ensure that the
buckle springs back in place.
