Maybe you could use one of those cellphone amplifiers. I'm using one myself.

I heard someone say that Three use their own Cell towers unless there's ZERO coverage. So if you are in a region with 4% Three tower coverage and 98% Telstra, it will still use the 3 Coverage. (I think there's a way to change it but it requires magiking your phone

Which provider are you using? Do you always have the problem anywhere and anytime?

I remember that last time I had that problem too. I was with Three at that time. They mentioned to me that it is the black hole area. It means that you are on a bad coverage area because of your sourrounding such as high building blocking the reception.

I seem to be getting a lot more dropped calls nowadays - can't sustain a call for half hour even though i'm not moving much (at home) ... are other people as dissatisfied as me? I've gotta pay flagfall all the time cos of this - a conspiracy i say!
