General questions for AT cmds

Hi :slight_smile:
Yesterday I got my first SODAQ SFF board. I want to use it with the 1nce.de sim in Germany in the NB-IoT network.

Today I was able to connect to the telekom network using some AT cmds. I’m now curious if need these cmds during every setup to set the modem to my settings?

Commands I used to get a connection:
“AT+CFUN=15”,
“AT+CFUN=0”,
“AT+URAT=8”,
“AT+UDCONF=1,1”,
“AT+CMEE=2”,
“AT+CGDCONT=1,“IP”,“internet.nbiot.telekom.de””,
“AT+CFUN=1”,
"AT+COPS=1,2,“26201"”,
“AT+CSQ”

Best regards,
Tim

Now, out of the sudden the device get’s nor recognized by my computer anymore.
Any idea what could be wrong?
