Device connection issue

Hi all,
I am using Sierra sim for data connection.
here is log for cm command
root@swi-mdm9x28:~# cm data connect
Setting up profile 1
Connecting … ok
Checking if device ‘rmnet_data0’ is up … failed

Can someone tell me why is that happened??

Hi @vishalgore,

Which device are you using?
You can use command as below to check the interface is enabled:
at!unlock=“A710”
at!usbcomp?

You try to set :
at!unlock=“A710”
at!usbcomp=1,1,8010D
at!reset
Then “cm data connect” again.
