I cannot see any "AT^SYSCFG" call in that log, which is the 
Huawei-specific way to get/set allowed modes.. so there's something 
wrong somewhere. Specifying the allowed mode in the Simple Connect 
settings should trigger mode change if the current allowed modes are 
different than the requested ones.

Anyway, can you try to run the following between plugging the modem and 
launching the connection request (assuming here the modem gets index 0)?

$> sudo dbus-send \
    --system \
    --dest=org.freedesktop.ModemManager \
    --print-reply \
    /org/freedesktop/ModemManager/Modems/0 \
    org.freedesktop.ModemManager.Modem.Gsm.Network.SetAllowedMode \
    uint32:4

Cheers,
