The condition you're seeing is also well-known as the "3G - 1X Dance". I see this from time to time in a location that never changes. I'll have a very strong Singal strength - 4 bars - and the 3G will just switch to 1X for a minute or so, then back to 3G ... all the while the 4 bars don't change. Nobody seems to know wht this happens; or at least there does not seem to be a "fix" for it, yet. You can search the MOTO forum for a lot more discussion on this.
Thanks again to both of you. Helps me to understand what's going on. As I said, I was having problems not getting calls and opened up a trouble ticket with Verizon and they said that others in my area were also having the missed call problem, but apparently they aren't doing anything about it because it's not getting better. They said they sent an engineer out and he did notice a problem but they apparently don't know how to correct it. They all agree that I'm so close to a tower that I shouldn't be having that problem, but I am. I sit here and watch it "dance" back and forth between 1, 2, 3 and 4 bars. Oh, but of course I can spend $249.00 on an extender, or I can just live in a certain area of my house where I consistently have better reception. Didn't have this problem with the #1 provider and if it wasn't for the ETF I'd go back. Only reason I'm ranting is because I missed a very important call from my doctor and it really bothered me that I just happened to open the phone and see that I had received a voice message a couple of hours earlier without any notification.
Sorry for the rant and again, thanks for the information.
