in some areas, especially tall building [high floors >10-20] i notice maxis 4g totally weak only EDGE. Whereelse Digi even in fact Umobile can get full 4G or marginal 4G still. This is the experience i had in KL, PJ condos/business towers. However, if speed Maxis i can say is blazingly fast or better than Digi or Umobile but of course subject to location.

For new residential place, Maxis unfortunately have bad signal but what caught my suprise was DIGI and even Umobile sometimes they have tower newly setup in a new housing community....bravo.
