I've had no trouble with Verizon in Chicago and many suburbs. I looked at Sprint, which was my original choice and in 2002, which is when I signed up with service, and Sprint wanted $35 for 200 minutes and unlimited nights and weekends and Verizon offered $35 for 300 minutes and 3000 nights and weekends. When I looked at coverage and anytime minutes, I chose Verizon Wireless and have had few problems. Most of my problems are typical problems. The only time I have problems is when I go into Michigan on Alltel's network. As for Nextel, I think the service costs too much, and I personally don't like walkie talkie phones. They might be fine for some people, but it's not for me. Plus, my mom and sister had the service and wasn't all that happy with it. plus, I don't like the idea that they use a proprietary digital standard and don't offer analog backup if you go off the network. Which means you go off the network, you don't have service,and that's what happened one time when my mom and sister got lost in Renssalaer, IN and was off the network. They had to ask people for help to get where they needed to since the phone was useless there. I wish the FCC would have approved one digital standard years ago to where we wouldn't be in the mess of 3 digital standards (GSM, CDMA, and Nextel's IDEN. TDMA is being phased out). For where I travel, Verizon does well, though some phones don't work as well on their service as others do. I may get the Samsung SCH-a650 as my next phone. Motorola 120c and 120e are garbage for Verizon Wireless unless you're in an area with strong signal strength.
