I'll try to reproduce myself, but cannot do that right now as I don't have 2 SIM cards at this very moment. Anyway, could you get me ModemManager and NetworkManager debug logs when you reproduce the issue yourself? http://www.freedesktop.org/wiki/Software/ModemManager/Debugging/ I'm not sure how this can happen in MM, as the modems are fully isolated from each other, so if this really is an issue it may be that some other process triggers the disabling of the modems when one goes disabled or something.

My apologies, should be ok now. So, it looks like NetworkManager sees that the modem #0 is being disabled, and after some checks it ends up also disabling the modem #1... Could you please report the bug to the NetworkManager mailing list? https://bugzilla.gnome.org/enter_bug.cgi?product=NetworkManager Thanks!

I'm on Ubuntu 14.04 on a 32-bit machine and using ModemManager 1.4. I've also tested the following on ModemManager 1.0 with the same results. I'm in a scenario where I have two MC7304 Sierra modems, both connected to ModemManager through USB. When I issue 'mmcli -L' I get the following: /org/freedesktop/ModemManager1/Modem/1 [Sierra Wireless, Incorporated] MC7304 /org/freedesktop/ModemManager1/Modem/0 [Sierra Wireless, Incorporated] MC7304 I then enable both modems. I do this by issuing the commands: mmcli -m 0 -e mmcli -m 1 -e Both end up in state 'registered'. So far so good... | state: 'registered' However, when I disable one of the two modems, and only one, the other one disables as well. If I issue the command: mmcli -m 0 -d both modems will end up in: | state: 'disabled' It seems that disabling one modem disables the lot of them. The same principle applies for 3 or 4 modems which I have also tested.
