Hello,
Apologies for the delayed response.
The issue is specific to the Verizon network and is more complex than this command. Thus, this will not be included in the next firmware as it cannot be changed easily. For these specific Verizon SIM cards, you can use the command provided above.
As for the persistance of the command, I suggest you put it into the custom scripts in System → Maintenance → Custom scripts. This way, the command will be executed automatically after every reboot.
Kind Regards,
