I am experiencing similar issues when trying to set allowed mode to all modes, and
preferred to "none in particular" :) .
Simply doesn't work - even with a success message then settings remain so that
preferred mode looks to be 4G. Would like very much to solve this.

Subject: AW: Set allowed mode to 2G, 3G, 4G not working
Hi,
I've just updated MM from 1.10.0 to 1.12.0 with the result, that my application
fails when setting the mode ('2G|4G') for Telit LE910-EU1. It also fails when
using mmcli.
My version 1.10.0 contains Daniele's patches mentioned here
https://lists.freedesktop.org/archives/modemmanager-devel/2019-February/007044.html
and in following messages.
I assume, that Daniele's patches didn't go mainline.
Daniele, can you send a merge request, containing your patches for the master
branch?
I'll test them as soon as possible with Telit LE910-EU1 and give you feedback,
such that this feature can be released.
Thank you for your help.
Carsten

Hi Daniele,
Thank you. Yes, I'll give it a try tomorrow.
Following patches from your commits should be applied to MM 1.10.0

Is this right?
Best regards,

Hi,
I must correct me, modem type is LE910-EU1 as Reinhard assumed. Sorry for this
confusion.
As a workaround for testing, we send AT+WS46 commands via D-Bus, but that seems
possible only, if MM runs in debug mode.
If we need this feature for production in the future, I understand that we can
add it to the Telit plugin.
at the following link
https://gitlab.freedesktop.org/dnlplm/ModemManager.git
you can find a fork with two additional commits that should implement
what needed.
Before sending to Aleksander a merge request would you like to give it a try?
Regards,
Daniele
I'd be very happy, if you can support me during implementation at a later point
in time.
Thank you Aleksander and Reinhard for your support.
Carsten

Within the debug output I found the following line
ModemManager[623]: <debug> [1550762368.321591] MBIM-powered Telit modem found...
which points out, that calling
if (mm_port_probe_list_is_xmm (probes))
did not find the XMM support.
It didn't find it, because the XACT=? check failed:
ModemManager[623]: <debug> [1550762359.960165] (ttyACM0): --> 'AT+XACT=?<CR>'
ModemManager[623]: <debug> [1550762360.882668] (ttyACM0): <--
'<CR><LF>ERROR<CR><LF>'
So I assume the XMM support that we have in the xmm plugin isn't ready
to handle this specific device.
The inability to switch modes in this device is not a bug, it's just
not implemented I'm afraid.
Hi Aleksander,
the Telit-preferred way seems to be to handle this with AT+WS46.
I haven't checked the code in detail but based on the AT+WS46
references in the Telit plugin I would have expected for
ModemManager to already use it.
If the modem is managed with MBIM, the generic MBIM implementation is
used for the Telit modem, so no AT+WS46 based mode switching will be
done. For this kind of cases, where we have MBIM for generic control
plus AT for other features, we would need to have a
"MMBroadbandModemMbimTelit" implementation that inherits from
MMBroadbandModemMbim but then shares features with the Telit-specific
AT modem object. So, it's totally possible to do this, but needs to be
done.
