AT&T SIMs not working (GL-X3000)

Routers

Per some other forum post I have updated to the 4.8.0 beta firmware but there are fewer options to set not more. I don't see a way to override the APN or even go to Manual Settings for LTE. I can't even tell it which SIM to use; the OG firmware had a "flip" button and the beta does not.

Per Cellular Network Troubleshooting Guide.html, there are no module upgrades available.
I do not see any profiles for AT&T and it is not clear to me how to add a profile manually.

The QCM protocol does not seem to be exposed to the underlying Luci GUI so I can't tweak options manually there.

I can scan towers and see AT&T networks, -12 ~ -10 dB RSRQ as we're indoors, but selecting them does not establish a connection and I want to roam not lock to a tower.

It appears to be selecting "resellermht" for the APN but I believe it should be nrbroadband (5G) or broadband (4G).
How can I override this?

Hello,

May I know did you find to way how to configure the custom APN in v4.8?

Please refer to this guide, it is in the "SIM Card Settings":

I did and wanted to capture it here for others to read because the GUI is bugged.

If you enter the APN and hit [enter] it will reset the field to the last value not accept the change, which led me to conclude it was read-only and not editable, hence this post.
(This should be filed as a bug to fix.)

If you exercise restraint and type in the APN then click off the field and click Apply it will take.
Then I was able to connect to the AT&T network (using nrbroadband for the 5G SIM and broadband for the 4G SIM).

Thank you for your feedback.

I will try to reproduce this issue and submit to R&D to check.
