3.1.1 4G card access to the network
On the right side of the machine, the position of the laser slot (as shown above) is the 4G card slot of
the router. The card slot is covered by a metal cover, fixed with a magnet, and can be easily removed
by a suction cup.
SIM card only supports Micro-SIM type, size: 15mm in length, 12mm in width, and 0.76mm in
thickness.
When installing the SIM card, you need to make sure that the chip position is facing upwards, the
notch position is facing inward, and the card slot is aligned and pushed inward. After pushing it to
the bottom, the installation is successful after hearing a light click.
When the SIM is networked, it is necessary to ensure that the 4G signal in the current machine
operating environment is good.
The SIM card needs to ensure sufficient traffic before it can access the network normally.
If the operator stipulates that the SIM card needs to be bound to the device, you need to
determine whether the SIM card has been bound by other devices before use.
