Why digi network indoors poor?

[Ariff]

I live in Seremban. Here got 3g network. That's good enough, BUT, only for outdoors. Indoors, it's **bleep** terrible. I done my research and found that Digi is using GSM 1800 compare to other telco GSM 900. The disadv. is 1800, didnt penetrate well through walls and bricks because of shorter wavelength. So Digi, give me explaination, why on earth you still choose GSM 1800? I keep on getting low quality phone calls (fading voices, etc) indoors. Do I need to go outside just to answer some calls? Come on. Do us some favours by at least change to GSM 900 or upgrade please. I know im not the only customer that is having this nightmare. You are losing too many customer because of this despite great plans you are offering. Please, and please do something about it.

DiGi can't operate their network on 900MHz frequency, simply because MCMC didn't gave them the license to operate at this band.
