LTE connection error 0x7

Hello, we are having problems with our RAK LTE connection.

We already checked the Fequencies and everything should work, but is giving us an error.

We follow the manual and all their steps and nothing.

Here is our log:

+COPS: (1,“CLARO URUGUAY”,“CLARO UY”,“74810”,7),(1,“Antel”,“Antel”,“74801”,2),(1,“Movistar”,“Movistar”,“74807”,2),(1,“CLARO URUGUAY”,“CLARO UY”,“74810”,2),(1,“Antel”)

Next, execute the AT command “at+cops=1,0,XXX,YYY” to set theinformation of the LTE network operator that you want to use. “XXX” is theoperator identifier, for example, “CHINA MOBILE”, “CHN-UNICOM”, or"CHN-CT" in the above picture (“Vivacom BG”, “Telenor BG”, or “Mtel” for theEU example). “YYY” is the last value of every operator, choose the one withthe 0 value as this is the currently used network.
