USA -> Malaysia -> South Africa - it worked a little in Malaysia, no service in SA

Hi everyone, I have a bit of a weird situation and I'm hoping someone with experience can point me in the right direction.

I bought a Note 8 (second hand) in Malaysia. It's a US snapdragon version:

When the phone boots it shows the XFINITY logo.

SM-N950U, Baseband Version: N950USQS5CRG9

Service provider SW ver. :
SAOMC_SM-N950_OYN_CCT_OO_0024
ce071717888898f80d7e
CCT/XAA/CCT

Android Security Patch Level:
August 1, 2018

The phone worked in Kuala Lumpur, Malaysia, but not very well. I was using a Malaysian uMobile simcard. There were a few places where I could make calls.. but in most areas only the LTE worked.

I usually couldn't make or receive calls or get SMS or even use MMI codes (like *123# to check balance). I could browse the internet though.
I then traveled to Malacca (a smaller city in Malaysia) and I couldn't get the phone to work at all anywhere - not even LTE.

I'm now back home in South Africa and again, the phone doesn't work here at all. I've tried sims from all the providers here. Is there a firmware I can flash that would help? I've been reading this thread, and it's a little confusing to know which versions to flash and in what order. Before I attempt something, I just wanted to run this by you guys and make sure it's not in vain, and that this phone can be made to work in South Africa?

Only the cellular functions of the phone are not working. Wifi works fine. I also noticed some people mention that they have an airplaine mode icon, I do not. I have have a circle with a line through it, and a message "No Network Connection"

All I want is to be able to make phone calls and use internet - I don't need wifi-calling or anything carrier specific. The South African networks are Vodacom, CellC and MTN - I've previously bought phones from the USA that work here before.

I don't think my phone is carrier locked because it did work a little in Malaysia depending on where I was.

When I use a sim from a carrier here called MTN:
I fiddle with the Network Mode, switching between LTE/3G/2G and 3G/2G in Settings->Connections->Mobile Networks - I get a few bars of connection, but when I try to do anything it says "Not Registered on Network"

When I use a sim from a carrier here called Vodacom:
If I go to network operators and search networks - it shows all the south african networks - I select Vodacom (for this sim) - I get zero bars in the connection strength. In the notification pull down, it says "No Service - Selected network (Vodacom-SA) not available.

Thanks!

Update

I've attempted to flash an N950U1 firmware ( N950U1UEU5CRJ2 ) .. but still no cellular connectivity.

So far I've:

1. Did a factory reset.
2. Used Odin 3B(PatcheD) with the latest N950U1 XAA firmware from updato and used BL, AP, CP and CSC_OYM, and NOT HOME_CSC)
3. Odin Passed, and the phone rebooted and erased itself again.
4. When it booted it said "Your device will restart to configure features supported by the new sim card"
5. It rebooted, with a screen with a blue image of a sim card and 3 dots.. which stayed that way for a while, then again rebooted.
6. After rebooting again, I'm now in and everything works except the cellular stuff .. still No Service. The signal icon on top shows the empty triangle (no bars).
