-> error: couldn't scan networks in the modem: 'Zeitüberschreitung wurde 
(timeout was reached)

In the second trial it lists me 10 networks. This 'Zeitüberschreitung 
wurde erreicht' is also the error that I get after simple-connect. 

I tried the --set-allowed-modes and --set-current-bands flags for mmcli 
which you mentioned in your first reply. With the latter one I can set 
"any". For other bands I get a QMI protocol error (25): 
With --set-allowed-modes=3G or 4G it tells me 
error: couldn't set current modes: 
'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unsupported: Cannot 
change modes: only one combination supported'

Should resetting via mmcli -m 0 -r be supported for the MC7710? It tells 
me that it isn't :-S
Are these things that might work --with-newest-qmi?

Unfortunately this problem doesn't look quite systematic (yet). Did you 
see a similar behaviour with the MC7710 and did you use the 3.5.24
