Do you mean the data service to the yocto linux?
I don’t see any AT command can give such information.
Normally you need to check in console by “cm data”
e.g.:
root@swi-mdm9x28-wp:~# cm data
Index: 1
APN: hkcsl
PDP Type: IPV4
Connected: yes
Interface: rmnet_data0

Gateway[IPv4]: 10.109.95.161

Dns2[IPv4]: 10.144.148.5
Hello, I am having similar problem. I am not able to activate the external SIM.
I have tried the AT commands (attached). Also the CUSTOM commands, as mentioned Sierra Wireless AT command guide, are throwing errors.
Could you please list down the stesp/AT commands to enable this?
Additionally, is it must to set OCTAVE=0 to enable the external SIM?
