Dear @Ham
It is strange.
Do you have USB on your device? Is it possible to capture log?

Sorry, I don’t know what usb can you tell me like uart??

I think it is possible but I don’t know how to do it

Where download this tool?

Dear @Ham
Which OS do you use? Linux or WIndows?

Dear @Andy.alex
What do you mean? The tool to capture log?
Which OS do you use? Linux or Windows?

Windows 11 driver quectel ndis 2.8

Dear @Ham
For windows driver, you can download from website.

Still same

I just buy new usb to m.2 key b from waveshare
it works but 1:3:40 and 5g nsa doesn’t
i try lock 1:3:40 doesn’t work only if b28 is Pcell

Dear @Ham
Do you check with operator which combinations are supported?
Form your description, some NSA combinations worked fine, right?

For 4g in my area is 28+1+1 1+1 28only
5g nsa 1_n28 and n41 3-1_n41
