I recently replaced an EM7455 with an EM7411 that I purchased here. I swapped the SIM, which is activated with Verizon, into the new 7411. Once it was installed and we tried to use it it's showing "disabled" for its status:

This is on Ubuntu. We tried 'nmcli r wwan on' as well as at!pcinfo? but no issues there:

Code: Select all

We checked with Verizon and it's showing up as active in their system. They see the new IMEI, too.

Is there an 'enable' command we're missing?

Thanks!

Solved my own problem after much research..

The new modem has to be enabled like this:

sudo mmcli -m 0 -e

In this case my modem is 0, from 'mmcli -L'

mmcli is the commandline version of ModemManager since we're using Ubuntu Server.
