Can PHU tester of Huawei change RAT even locked?

Hi Experts.
Can PHU tester of Huawei change RAT even locked?
Please provide insight.

It will not change.
If you can, I highly recommend you to lock the frequency.

But I locked RAT to 4G and 5G only.
UE still latch to 3G.
I went on fly mode and comeback.
Initially it latch to 5G, then went on 4G and finally again latch to 3G.

You must run the task.

Same while task running as well…

It works for me. :frowning:
Which version are you using?

Using version 5.3.5.

Maybe it’s a bug. Works properly here.

Yes, maybe.
Even if there is interference, it should camp on 4G or 5G only.
