GSM device unavailable in NetworkManager

I've been trying for the last few days to set up a GSM connection on my new ubuntu box. However, I can't seem to get Network Manager to manage it correctly. The box is a compulab fitlet2 and the cell card is a simcom 7100A. $ nmcli d DEVICE TYPE STATE CONNECTION enp2s0 ethernet connected enp2s0 enp3s0 ethernet connected Wired connection 1 tap0 tun connected tap0 wlp1s0 wifi connected MSI WiFi 2.4Ghz cdc-wdm1 gsm unavailable -- lo loopback unmanaged -- $ lshw *-usb:1 description: Generic USB device product: SimTech, Incorporated vendor: SimTech, Incorporated physical id: 2 bus info: usb@1:8.2 version: 2.32 serial: 0123456789ABCDEF capabilities: usb-2.00 configuration: driver=qmi_wwan maxpower=500mA speed=480Mbit/s $ lspci 00:00.0 Host bridge: Intel Corporation Device 5af0 (rev 0b) 00:02.0 VGA compatible controller: Intel Corporation Device 5a84 (rev 0b) 00:0e.0 Audio device: Intel Corporation Device 5a98 (rev 0b) 00:0f.0 Communication controller: Intel Corporation Device 5a9a (rev 0b) 00:12.0 SATA controller: Intel Corporation Device 5ae3 (rev 0b) 00:13.0 PCI bridge: Intel Corporation Device 5ad8 (rev fb) 00:13.1 PCI bridge: Intel Corporation Device 5ad9 (rev fb) 00:13.2 PCI bridge: Intel Corporation Device 5ada (rev fb) 00:15.0 USB controller: Intel Corporation Device 5aa8 (rev 0b) 00:18.0 Signal processing controller: Intel Corporation Device 5abc (rev 0b) 00:18.1 Signal processing controller: Intel Corporation Device 5abe (rev 0b) 00:18.2 Signal processing controller: Intel Corporation Device 5ac0 (rev 0b) 00:18.3 Signal processing controller: Intel Corporation Device 5aee (rev 0b) 00:19.0 Signal processing controller: Intel Corporation Device 5ac2 (rev 0b) 00:19.1 Signal processing controller: Intel Corporation Device 5ac4 (rev 0b) 00:19.2 Signal processing controller: Intel Corporation Device 5ac6 (rev 0b) 00:1b.0 SD Host controller: Intel Corporation Device 5aca (rev 0b) 00:1c.0 SD Host controller: Intel Corporation Device 5acc (rev 0b) 00:1e.0 SD Host controller: Intel Corporation Device 5ad0 (rev 0b) 00:1f.0 ISA bridge: Intel Corporation Device 5ae8 (rev 0b) 00:1f.1 SMBus: Intel Corporation Broxton SMBus Controller (rev 0b) 01:00.0 Network controller: Intel Corporation Wireless 8260 (rev 3a) 02:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03) 03:00.0 Ethernet controller: Intel Corporation I211 Gigabit Network Connection (rev 03) $ mmcli -m 0 /org/freedesktop/ModemManager1/Modem/0 (device id '036a0672f2e8521a8489d65396456527879b5df6') ------------------------- Hardware | manufacturer: 'QUALCOMM INCORPORATED' | model: 'SIMCOM_SIM7100A' | revision: 'M9615A-CETWTBZM-6.0.15255 1 [May 13 2016 01:00:00]' | supported: 'gsm-umts | lte | gsm-umts, lte' | current: 'gsm-umts, lte' | equipment id: '014339000192712' ------------------------- System | device: '/sys/devices/pci0000:00/0000:00:15.0/usb1/1-8/1-8.2' | drivers: 'option1, qmi_wwan' | plugin: 'SimTech' | primary port: 'cdc-wdm1' | ports: 'ttyUSB0 (qcdm), ttyUSB2 (at), wwp0s21f0u8u2i5 (net), cdc-wdm1 (qmi), ttyUSB3 (at)' ------------------------- Numbers | own : '19708529168' ------------------------- Status | lock: 'sim-pin2' | unlock retries: 'sim-pin (3), sim-pin2 (3), sim-puk (10), sim-puk2 (10)' | state: 'searching' | power state: 'on' | access tech: 'umts' | signal quality: '65' (recent) ------------------------- Modes | supported: 'allowed: 2g, 3g, 4g;
