I had been using the GS3 for a couple of years, with lots of connection problems, and did the upgrade to the GS4. "No service" was the common connection statement at home. Switched for the iPhone 5 and have 2-4 bars, at home, and found lots more service on the road. Went fishing and had signals in numerous places where both the GS3 & GS4 showed no service. Really liked the SD card capacity, android easy to work with, but much prefer having phone service in a much wider area that iP5 provides. Still learning the iP5, and its differences, but am very pleased with the service area increases.
