Nope - both Cinterion, but different models. > 2) Modems do store some state in NVRAM. Sometimes that can include > things like the default authentication mechanism (CHAP vs. PAP vs. > none).

Working: mmcli -m 0 --command="AT+CGDCONT?" response: '+CGDCONT: 1,"IP","wap.vodafone.co.uk","0.0.0.0",0,0 +CGDCONT: 2,"IPV4V6","wap.vodafone.co.uk","",0,0' [MM log showed cid 1 being used in the AT*99] Non-working: mmcli -m 0 --command="AT+CGDCONT?" response: '+CGDCONT: 1,"IP","wap.vodafone.co.uk","0.0.0.0",0,0' I'm not sure where/when the 0.0.0.0 got inserted in the Working one. It *wasn't* there to start with on the non-working one, so when I saw that diff I re-configured to add it. But not working with nor without that field. > I assume these are Cinterion devices?
