You have to buy a Samsung with Exynos chip to be able to do that.

Not sure. My cousin bought S20+ Snapdragon and cannot access #2263.

Let me try later with my mom's new S22U.

I do have 2 Tab S6 to try as well.

Update:

Forgot to try with S22U but tried on my Tab S6 with SD855 and indeed #2263 works. Maybe he bought telco set which had this disabled.

If it is 4G+, it basically means it is connected to more than 1 band. If you want to check, try using *#*#4636#*#*. It works on my cousin Mi10.

Telcos are already using 4G on almost all the bands, namely 1,3,7, and 8 (depending on which telco, big 3 should have all these bands). Usually if you are having bad connection indoors, you would want to turn off Band7 as the 2600MHz band had bad wall penetration. For me, I personally feel Band 3 (1800MHz) offer the best compromise between speed and connectivity.
