i know that the number of bars really doesn't mean anything but i got a prepaid tmobile card for my V3 to try it out to see if i can go prepaid since i don't use it that much and when the phone is idle, it shows one, maybe two bars but when i make or receive calls, it jumps to full bars, is this normal? i'm in middlesex county nj, which is central nj. thanks
Depending on network configuration this is perfectly normal. Sometimes when you have your phone stuck in your pocket it may not get good reception but if you pull it out to answer or make a call it could take a few seconds before it switches to a stronger channel which is why you see the change to full bars.
