generally
celcom and maxis using fdd band 3/7
digi using fdd band 1/3/7/8
umobile using fdd band 1/3/7
unifi using tdd band 5/38/40
to check phone support which band can check at gsmarena or phone specification.
from my observation
place with band 38 coverage only have band 38 coverage.
place with band 40 coverage only have band 40 coverage.
not exactly, it depends on the location and geography. Lets say you are 5KM away from Band 40 coverage; if you are living on highrise like Level 15 with no other high rise building blocking direct angle to broadcast tower or other magnetic interference like TNB's overhead transmission line, you will still receive the TDD signal but weaker even tho TDD can only travel far up 2KM (with obstacles).
The rules of radio waves also applies, something you can learn in radio amateur.
Like in my case I'm living 7KM away from TDD area but due to im living in highrise I can still get Band 40.
