ppp can connect, but maybe not with ModemManager. I'll have to trust Marius on that.

NetworkManager and ModemManager are dbus-based daemons and should work fine on embedded systems. See e.g Aleksanders work on OpenWRT: http://sigquit.wordpress.com/2013/02/14/modemmanager-and-latest-udev-in-openwrt/ > Another question: Is it important for dialin-procedure if I have an > access-point with LTE or UMTS?

In my very limited experimenting I could never get more than ~8Mbits/s uplink with PPP. I get >30 Mbits/s up using the same MC7710 card with any of the supported network interface protocols (DirectIP, QMI, MBIM).
