Hello again,
I installed again Ubuntu and dmesg shows me this:

The modem is configured for MBIM only. The newer Windows drivers will do this if they find a modem in QMI mode.

See My MC7710 can't work on Linux after plug-in it to Windows8 for a solution. But please read the following comments too for more details, in particular
mattfox’ hints on necessary perl modules ( viewtopic.php?f=117&t=8863&start=15#p37211 )
and KiernanV’s instructions on how to configure the Windows driver for more useful modes ( viewtopic.php?f=117&t=8863&start=15#p37212 )
