Description
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'
