Need help with Network Unlock and/or Reactivation Lock

So I got this N910A from my aunt from the US who passed it down to me and I forced factory reset it after she gave it to me through the bootloader. Anyway, she tells me she forgot her Samsung account and password so I had no choice but to go through the Aptoide route to be able to use it again. I'm asking help on what I should do to be able to use the phone with my country's simcard because it's network locked. I could do without the reactivation lock since I can use the phone anyway, but having the Samsung account removed permanently so I can add my own would be a great help because currently, adding a "Samsung account" through Settings > Add Accounts doesn't do anything when I tap on it
Here is my phone's information.

Airplane mode is toggled when sim is installed

When I install sin in a sm-975u note 10+ us version, the airplane toggle lites up halfway dim and no cell service icon is where the signal level is normally the screen has been changed and the boards seem to be correctly matching. When I got the phone it was Google locked I paid an ebay company to fix and seems they did fix frp. The phone had Verizon icons I sold it to a friend he put a at&t sim and the phone didn't work so I put a verizon sim in and no luck. I did a imie on byop on verizon and swappa phone is good to go

Samsung Galaxy S20 Ultra SM-G988B Debrand from provider

Hello,
My Samsung Galaxy S20 Ultra 5G/SM-G988B needs to get debranded completely from provider!
At this moment my csc code=PHE/PHE,PHE/EUX/ATL= sales code/sim1,sim2/samsung/provider, so with Samkey I have changed the sales code and the 2 sims their csc code from ATL to PHE!
Now I hope that there are intelligent people who can tell me how I can change the last ATL code in the csc which is called AID as csc code!
That you can see in the screenshot from download mode that I will add to this message!
So I hope for a positive response from somehow who has figured it out how to change

Is the phone really network unlocked or it can't be unlocked ?

Hello guys,
I have a G7 Thinq, Model: LM-G710TM. When I bought I think it said that it can only be used with T-mobile and it has worked perfectly so far since my carrier is T-mobile.
I was looking at the installed apps more carefully and I saw that the phone came with an "Unlock" app and I went ahead and clicked it. Now the app says that the phone has been permanently unlocked and can be used with any carrier.
I was wondering if anybody has tried this and can confirm if the phone is truly carrier unlocked or not ?
I had a few international Sim cards from past travels but they have all been deactivated since I didn't use/recharge them for so long and I can't test it myself.
Thanks
