If the connection attempt fails so quickly, it could be the network
failing to setup the connection. Are you sure the APN is the correct
one? Maybe try to use --simple-connect="apn=everywhere,ip-type=ipv4"
to force IPv4-only?
Also, you should not do any manual --simple-connect, better setup the
connection using the System Settings and NetworkManager.
