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

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.

Could you try investigating how much of the system has been set up? Fx. using ifconfig can you see if the inerface rmnet has taken the mentioned ip and gateway? Looking in /etc/resolv.conf can you see if the two DNS’s has been written there correctly. Using route can you see if a default route has been added to use the specified gateway and interface (https://www.cyberciti.biz/faq/linux-setup-default-gateway-with-route-command/)?

All the above can help diagnose where in the process the cm data connect command failed.

@vishalgore, can we know if the issue is still current?
