Is there anyone that can answer this simple question?
How can the signal on my phone vary from "no signal" through the entire range to 3G and back whilst I am totally stationery?
From my basic education I understand the concept of sound and radio waves.
So how does it vary so widely when the phone doesn't move more than a foot (30 cms) in any direction. There are no objects moving that could mask the waves...
E.g. An SMS message comes and is received. It is read but the user is unable to reply as the phone has no connection to the network.
Irritating but how can this happen?
