Cannot get IPv4 address from EE UK with MC7455

[Cian Masterson]

Hi,

I'm using a SIM from EE UK with a Sierra Wireless MC7455 modem and when I
try to connect it fails with the error "[3gpp] ipv6-only-allowed".  The
command I'm using is

qmicli -d
/dev/cdc-wdm2 --wds-start-network=ip-type=4,apn=everywhere,auth=chap,username=eesecure,password=secure
--client-cid=35 --client-no-release-cid

The response I get is:

ERROR: error: couldn't start network: QMI protocol error (14): 'CallFailed'
call end reason (1): generic-unspecified
verbose call end reason (6,51): [3gpp] ipv6-only-allowed

If I change "ip-type=4" to "ip-type=6" in my original command above it
connects ok and gives me an IPv6 address, but I would rather get an IPv4
address.  Is it possible to force this?

If I use the same SIM with an old uBlox Toby L210 modem it connects just
fine and grabs an IPv4 address, so I figure the network supports it and I
can't figure out what the two modems are doing differently.  The uBlox uses
AT commands, so hard to compare.

I've tried leaving the "ip-type=4" out of the string but get the same
result, as I'd expect.  Am I missing a parameter?

Slan,
Cian
