how to access Internet using modemmanager and not network-manager

I recently bought a tata docomo dongle. On inserting it I got the below details :- Aug 05 17:30:46 think-debian kernel: usb 1-2: new high-speed USB device number 5 using xhci_hcd Aug 05 17:30:46 think-debian kernel: usb 1-2: New USB device found, idVendor=12d1, idProduct=1f01 Aug 05 17:30:46 think-debian kernel: usb 1-2: New USB device strings: Mfr=3, Product=2, SerialN Aug 05 17:30:46 think-debian kernel: usb 1-2: Product: HUAWEI Mobile Aug 05 17:30:46 think-debian kernel: usb 1-2: Manufacturer: Huawei Technologies Aug 05 17:30:47 think-debian mtp-probe: checking bus 1, device 5: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-2" Aug 05 17:30:47 think-debian mtp-probe: bus: 1, device: 5 was not an MTP device Aug 05 17:30:47 think-debian systemd: Created slice system-usb_modeswitch.slice.
