Please do the following:

devel-su
mkdir -p /vendor/oem/modem-config/S264.6/
mkdir -p /vendor/oem/modem-config/S264.8/
echo -n 'mcfg_sw/generic/euro/dtelekom/vlvw/de/mcfg_sw.mbn' > /vendor/oem/modem-config/S264.6/modem.conf
echo -n 'mcfg_sw/generic/euro/dtelekom/vlvw/de/mcfg_sw.mbn' > /vendor/oem/modem-config/S264.8/modem.conf

then reboot and enable 4g calling from the Cellular settings page.
