LTE B20 band on PIC-LX9 not working - Huawei Nova 2 Questions & Answers

Hi,
on Ebay I bought a brand new Huawei Nova 2 PIC-LX9. This is a variant that should be able to operate on LTE band B20 800MHz.
Unfortunately, in places where only LTE B20 band is available, the phone is connected to EDGE . I searched a bit and found out that the model designation differs in several places:
in the android settings - PIC-LX9
in the engineering mode (after entering the code *#*#2846579#*#*) - PIC_AL00_VE
on the box and battery cover of the phone - PIC-LX9
in the Chinese manual - PIC-AL00.
I have few questions:
-what´s problem with LTE ? Bug after update? Or is this a rebranded phone?
-Is the hardware of all Nova 2 variants the same?
-Is it possible to unlock/enable the B20 band?

Are there VARIANTS of i9195 with different radio bands? Or just software ?

Are there PHYSICAL different radios between i9195 per carrier
or just SOFTWARE as some have different bands available?
I want to buy a phone on EBAY to use in New Zealand, Australia
3G: 850 (New Zealand), 2100 (Australia)
4G: 1800
Samsung S4 E370K i9195 description does not include 850MHZ 3G.
Will it work if I flash a custom rom?

Galaxy s9 bad reception

So I have galaxy s9(SM-G960U) with (G960USQS7DTD1) software version and its snap Dragon American version , I got it from amazon
I live in egypt so the problem is that , the phone reception is totally sucks , I cant even use 3G inside the house , my previous galaxy s7 has a decent 4G coverage inside the house
not only this , but the phone has a sprint activation software that keep checking for my sim card to check whether its sprint or not (like the picture)

So I think my problem is that I have limited frequency bands support which is being used by sprint network
so is there any software solution for this ?? like flashing any other global samsung software rather than sprint one ??
is frequency bands support is limited by software or hardware or both of them ??
I bought 2 phones unfortunately and I cant even sell it or return it back , So could you please help

Question 5G bands with AT&T prepaid

AT&T told me that I have to upgrade my prepaid plan in order to get 5G speeds (I know, they're not really 5G), and I don't want to keep $1100 phone and pay more for service if I am unable to get them because phone does not have correct bands. Three websites list different bands for US model and I could swear OnePlus website did not list bands n260 and n261 a week ago. Then who is finally right?

Or finally OnePlus?
If you buy the North American variant, the bands are there.
But the problem with AT&T is that OnePlus has not certified
the 9 series for their 5G network so you wanna double check that
but regardless you have to buy the correct model for North America(U.S & Canada).

Question no L5 GPS bands on Galaxy s22 but exists on Galaxy s22+? ways to enable?

according to this open data about GPS abilities for different phones, the galaxy s22 does not seem to have L5 GPS support but the s22+ does? Is there a way to get L5 GPS enabled on the base model s22? the 8gen1 chip supports it, not sure why it would be disabled.

In the same category S22+ supports Wi-Fi 6e but S22 doesn't while they have the same modem.
Your best bet is to ask to someone who made a custom kernel
