How to get IP address

[Tony]

Hi,
	I have managed to connect to EE network. But how do I get an IP 
address. I am using mmcli to make the connection. Most of the time it 
fails to make the connection.

--------------------------------------------------------------
mmcli -m 0 --simple-connect="apn=everywhere" --timeout=600
error: couldn't connect the modem: 
'GDBus.Error:org.freedesktop.ModemManager1.Error.MobileEquipment.GprsUnknown: 
Unknown error (256)'
------------------------------------------------------------------------------

Or

------------------------------------------------------------------------------------
mmcli -m 0 --simple-connect="apn=everywhere" --timeout=600
error: couldn't connect the modem: 
'GDBus.Error:org.freedesktop.libmbim.Error.Status.Failure: Failure'
----------------------------------------------------------------------------------


  But when it connects
-----------------------------------------------------------------
mmcli -m 0 --simple-connect="apn=everywhere" --timeout=600
successfully connected the modem

mmcli -m 0

I do not have an ip address. I tried to manually bring the interface up 
and get an ip address, without much luck.

sudo ifconfig wwan0 up
sudo dhclient -d wwan0

It keeps on sending DHCPDISCOVER on wwan0. Can somebody please advise 
what I am doing wrong?

Many Thanks,
Tony
