4G modem works only on LiveCD in Fedora

I run Fedora 24 as LiveCD (XFCE spin) and my 4G usb-modem works great. Then I installed Fedora on my hard disk and the modem does not work. On LiveCD NetworkManager automatically recognized the modem as mobile broadband, but if I run my system from hard disk, NetworkManager does not recognize my modem. By the way, I see my modem after lsusb command in the list. I do not understand why this happens, because the OS is the same. The modem type: Huawei E3372h
