What is the technical challenge in having low band 5G NR & LTE simultaneously?

Although this statement makes sense, I’m not sure operators will make any distinction on offering the service.

Yes, but the service offerings in SA will have distinctions based on user requirements categorized under each network slice.

Slicing won’t be necessarily optimized to start with.
There’s a lot of dependencies on 5GC and transport network to be solved along with it.

We updated the collection software.
The device actually went to NSA but DT tool was not using the latest Qualcomm ICD, so we couldn’t observe NSA metrics earlier.
We upgraded the DT tool and now we can see the NSA metrics in SA device.
Now the device stays on LTE-NSA.
