7490-m904 doesn't work

Hi, the router doesn't work with the SIMs of Fastweb operators, I also tried with Vodafone and Very Mobile sims but it doesn't detect the SIM.

in the SIM section the writing NONE or waiting sim available appears, but the network symbol remains red on the portal when accessing the router page. The router lights solid red
Is there a procedure or firmware to make it work and unlock, otherwise I will have to return the product because it is not working.
Thank you in advance for your answers
