IPv6 on Telstra network with EP06-E and OpenWRT

I am trying to get an IPv6 connection on the Telstra network in Australia using an EP06-E modem in a router running a version of OpenWRT.

I have only been successful with IPv4 connections.
I believe I should use an APN of either: telstra.internet or telstra.wap
I’m unsure what prefix delegation Telstra would be using - /64 ? /56 ?

Surely there is something simple I have missed…any help appreciated!

Hi,
Thanks for your query in Quectel forums.
Do you have the AT command document of EP06? You can configure your APN information according to the AT+CGDCONT command, thank you.

Having found no help or expertise on this (simple) issue, I slogged on to resolve it myself!

It turns out to be quite simple…the modem default profile was #1 (IPv4 only)
I found profile #15 was IPv4 or IPv6, so I made profile #15 the default.

From the CLI:
qmicli -d /dev/cdc-wdm0 -p --wds-get-default-profile-num=3gpp

qmicli -d /dev/cdc-wdm0 -p --wds-get-profile-list=3gpp

Changed default profile to #15 with the following:

qmicli -d /dev/cdc-wdm0 -p --wds-set-default-profile-num=3gpp,15

The modem then picks up IPv6 & IPv4 addresses, including a /64 prefix delegated range.
