Problem 4G LTE (DW5811e) DELL E5470

Hello everyone. I have a DELL E5470. So far I have done a lot of research and a lot of problems ... and here we are with the last one (at least hopefully). I bought a DW5811 Snapdragon LTE PCIe card (it is the module to use the mobile connection on the pc). As soon as it is installed, the module is automatically recognized by win10 .... the problem is that when I put the sim in the pc the "insert sim" item always appears ... as if the pc did not read it. Come on SIM I iliad. Has it happened to any of you? I also did the official test to install the drivers from the site but nothing. Also as regards the characteristics of the module, I have read what should be comaptiblie and among these Vodafone .... but except check iliad and not even wind, three, etc .. But shouldn't all SIMs be good? The frequencies are always the same, at least in Italy and for Italian operators. Isn't that a compatibility issue?
Thank you
