how about making a udp server on module and monitor what is received ?

Im going to test and I tell you later my results.

Hi, Sorry for my delay, but here I am. I configured the UDP Server and I Didnt receive any response from module 4G, what can I do? I stay tuned for your response. thanks.

Yes, even if I configure the module in 3g Operation it response the ping request, but when I turn back to 4G I didnt get a response.

I made a test connecting the 4g module in Windows 10 creating a COM Connection and It connect and I recieve the ping request that I made to Module, So I Dont think the movil Operator cant be the problem.

The UDP Server works in 3G and 4G, in LTE dont work.

You mean in lte, udp server does not work in all port?
