Just for clarity on my part, wouldn't it need to be at!band=0D,"B 66",0,0,0000000000000002 for band 66? 0A would refer to band 2, right?

For clarity on my part, would it need to be 0D instead of 0A? i don't know that I understand it.

Ok, I figured out that you must use AT!BAND=? to get the whole list. Sorry for the confusion.

I followed the steps in this guide, but I'm unable to get an IPv6 address from Sprint using the MC7455 with the newest generic firmware.

Code: Select all

at+cgdcont?
+CGDCONT: 1,"IPV4V6","r.ispsn","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
I also ran:

Code: Select all

At!custom="IPV6ENABLE",1
I'm using MBIM mode with ROOter (stable as well as the new 18.06 builds). According to the logs, the modem is simply not returning an IPv6 address. It says "iptype: 0001 - ipv4" in the logs, and the IPv6 address is set to "/64" (ie, blank). Is there anything else that I can try?

Are you capable of getting an IPV6 address on the hotspot?

It is possible the SIM Card and plan (from the device) will not receive an IPV6 address. The ZTE Pocket-WiFi is one such example.

You can use any index such as 0A or 10, 11, or 12 to name a custom band. You can always change the custom band later. That is shown in this tutorial. It all depends on what your band list says

As long as you don't lock bands on your modem, you should get CA (assuming its available in your area.)
