Hello!
We have VS-GW1202 with 2 VS-GWM400.
In 1st 4 ports we have 4 sim cards, and everything works. But in 2nd work only 1st and 4th ports.
Ports number 2 and 3 don't see a sim card and show the status "Not registered" (INIT). How we can make the initialization of new sim cards on these ports?
1st photo sim card in 2.1 port, 2nd photo sim card in 2.2 port.
Photo from terminal screen, sorry
First please check your module version under the menu module page ,

You can check the module version from web interface ,Module---select a port ,edit and you can the module version there . Or you can input the AT command under logs ----AT .input ATI to get the module version.
