maybe here someone can help me -
my modem show me Functionality minimum
and when I try to this :
AT!ENTERCND="A710"
At+cfun=1
at!greset
it doesn't help
also it doesn't save me the at+cfun=1 , it's return to at+cfun=0
why is it , and how do I make it work?
I have something like ~50 units and is the same in all of them
Thanks ,
