Let me know if you need anything more. Thanks. Looks like the modem is losing signal and/or registration state during the connection attempt, which is very weird... not sure what to say. Also have noticed that if the laptop is suspended the modem is missing after resume. Switching out of MBMI mode with some udev rules I am able to connect. # /etc/udev/rules.d/99_modem.rules

On a up to date Fedora 25 on a Toshiba Z30-C the modem and SIM all seem fine but it fails to connect. On a different Laptop with a 4G modem (much older laptop) the same SIM connects fine. I have double checked all the setting and am pretty sure all is correct. The state changes to connecting but never actually connects and after 10-20 seconds goes back to state: 'registered' ------------------------- Hardware | manufacturer: 'Sierra' | model: 'MBIM [1199:9063]' | revision: 'SWI9X15C_05.05.47.00' | supported: 'gsm-umts, lte' | current: 'gsm-umts, lte' | equipment id: '356906053323539' ------------------------- System | device: '/sys/devices/pci0000:00/0000:00:14.0/usb1/1-2' | drivers: 'cdc_mbim' | plugin: 'Sierra' | primary port: 'cdc-wdm0' | ports: 'cdc-wdm0 (mbim), wwan0 (net)' ------------------------- Numbers | own : 'unknown' ------------------------- Status | lock: 'none' | unlock retries: 'sim-pin2 (3)' | state: 'registered' | power state: 'on' | access tech: 'lte' | signal quality: '67' (recent) ------------------------- Modes | supported: 'allowed: 2g, 3g, 4g; preferred: none' | current: 'allowed: 2g, 3g, 4g; preferred: none' ------------------------- Bands | supported: 'unknown' | current: 'unknown' ------------------------- IP | supported: 'ipv4, ipv6, ipv4v6' ------------------------- 3GPP | imei: '356906053323539' | enabled locks: 'fixed-dialing' | operator id: '50501' | operator name: 'Telstra' | subscription: 'unknown' | registration: 'home' ------------------------- SIM | path: '/org/freedesktop/ModemManager1/SIM/0' ------------------------- Bearers | paths: '/org/freedesktop/ModemManager1/Bearer/0'
