I bought this phone already aware that the signal i was going to get wasn't going to be excellent as I had looked at the coverage map before hand. I haven't actiavted it yet, i've just been walking around checking the bars occasionally to see what the singal i would get is like. It seems to vary from 0-2 bars depending on where I am at at the time. I rarely ever make calls and I can access wifi at my house So i was just wondering if one bar is enough to send and receive text messages? Oh and also, does the amount of bars i have relate to the broadband signal I am getting at the time from sprints towers?
