Hello,

*wwan0-> is the name of the mobile interface when the connection type is set to QMI (default). You can use the ifconfig command to check the names of existing network interfaces.

* Basically both wwan0 and mob1s1a1 is the name of mobile interface. 

   mob1s1a1-> which you see via WebUI // wwan0-> which you see in CLI.

*If you are configuring the device via WebUI you can go for mob1s1a1 or if you are configuring through the CLI-> wwan0
