Hello,
When librem5 loses mobile data I have to reset the modem and disable/enable mobile data.
For the modem reset in command line it’s ok but I can’t find for mobile data.
Who can help me?

Have you looked into nmcli, similar to the Hotspot toggle commands described here?
Yes, I did it but my problem is not with the hotspot, which is working well and keep the connection up.
Sometimes, as reported many times in this forum, the mobile data connection stop working, the modem is connected to the mobile network but without data.
The solution is to reset the modem but just doing this is not enought, I havev to switch on/off the mobile data (currently in Gui Mobile Connection).
When I’m connected from my laptop far from the L5, I would like to do via ssh (hotspot still up) and I didn’t found the correct mmcli syntaxe.

The point I wanted to make is that it should be a nmcli invocation either way, regardless of Hotspot or mobile connection.
Run nmcli connection and look through the list until you find an entry whose type is gsm. (For me it’s Prepaid Contracts but yours may vary.) That’s the connection you want to bring down or up via nmcli.
Edit: Confirmed.
For me, it’s
sudo nmcli connection up 'Prepaid Contracts'
to bring the connection up, and
sudo nmcli connection down 'Prepaid Contracts'
to bring it down again.

Thanks a lot @Lliure I was looking at mmcli commands not nmcli.
So I just successfully tested it.

I have a bunch of such connections, which would be the correct one:
purism@pureos:~$ nmcli connection | grep gsm

The one where it says cdc-wdm0 at the end should be the correct one.
If the names are not unique, e.g. Internet, I think that nmcli allows you to pass the UUID instead.

Using the Librem SIMple plan, I’m able to toggle data on/off via the terminal using:
$ nmcli connection <up|down> fast.t-mobile.com

It does. I normally do that.
Probably time to clean some of those up …

When librem5 loses mobile data I have to reset the modem
Hello. I appreciate the solution and receiving the command. However, I have a bigger question: why does the mobile modem drop data so much? Is this problem being looked-at? Is this a fixable issue in Crimson? This is a rather large issue (as many others have noted in other posts).
Is Purism aware of this rather large issue and are they working on it?
Hello,
It is more frequent when suspend mode is activated, but not only.
I agree with this the suspend issue. However, it happens with and without suspend activated.
