I've had my Fascinate for about a week, and have experienced a few calls wherein the person on the other end of the line can't hear me speaking. My sister's husband just told me I should dial *228, and choose option 2, that it may improve my call quality. I just did this twice, the second time being that I was going to try option 1 (program phone), but then got scared of what that may do and picked option 2 again. So, I guess this updates your PRL? Preferred Roaming List? I know this has something to do with looking for cell towers, but don't really understand. I was reading about it online but... might this actually help call quality? Is there any downside to it? Can it hurt your phone? Is there any reason to dial *228 and choose option 1?
