My wife just purchased an Iphone. I had her get on Verizon because my Sprint is god awful. With Sprint I get no data in the West Loop. None. Zip. They recommend turning off 4g network mode to get better reception. Calls dropped. I'm hoping then to jump on her plan once my stupid Sprint contract is up. VZN speeds at home in Wicker Park are great, but down in the Loop she barely gets any LTE. Is there any carrier right now in downtown Chicago who can handle 4G/LTE capacity? Are both ATT and VZN swamped by too many 4G devices? We still got some time to dump VZN and jump to ATT but there just doesn't seem to be a clear winner until I can test ATT speeds in the loop too. Anyone got any numbers to compare? Any advice appreciated.
