Rak5860 problem

I have WisBlok with rak5860 module . Is 8 month i try to use this module. I write to Quectel but they say to write to Rak, and i WANT to use this module .
Some one can help me to find the right sequence of connection ( i’m using Vodafone ITALY , that use B20 band 800 Mhz ) . Until now i’ve seen the device connected only 1 time after 40 minute of network research, but it never transfer data ( according to the Nb Iot web platform ) .

Thank you in advance
