4.2.5 SIM card access and network service connection debugging
The LTE-LINK SE device does not support hot swapping of the SIM card, so please insert
the SIM card into the SIM card slot and connect two antennas at the same time before powering
on the device. After the device is powered on, it needs to judge whether the connected SIM card
is valid according to the indication status of the network card status light (LTE).

When the network card status light quick flashes twice continuously at a frequency of
1s, it means that the SIM card is not inserted or the inserted SIM cannot be connected
to the network through the LTE-LINK SE device.

When the network status light flashes once at a frequency of 1s, it means that the SIM
card has been inserted and the LTE-LINK SE device can connect to the network.
For the position of the NIC status light shown as Figure 3-2.
