Yeah, I heard these days even DiGi is better than maxis in areas like Subang, PJ and KL. My story is a bit different in a little kampung I like to call Klang, hehehe... I was with DiGi during iPhone 4 then switched to Celcom for iPhone 5 and this strange phenomenon was happening at home - my phone will show full bar of signal and I would get messages alerting me of missed calls. But my phone didn't ring. At first I thought the phone was a lemon, but I was getting calls fine in the office and on the road - just not at home. Gave a call to Celcom CS and they couldn't troubleshoot over the phone and asked to call me back. 3 days later, one officer called me back and explained that my housing area - or more specifically, my house - was located in this "blind spot" between two of their towers hence the signal there is bad. I asked why does my phone show full signal bar though and he couldn't answer. I asked what was the solution and he said unless I shift houses (really?) there's nothing he could do coz to boost the signal strength from their tower would require investment in equipment which they were not going to do. So yeah, ported out after the contract ended (thankfully there was still one year contracts back then).
