Is there a model of the Samsung Galaxy S4 with 64 GB of internal storage that is compatible with Verizon's 4G service? Verizon only sells a 16 GB version and apparently has no plans to offer higher capacity versions in the future. I know that you can upgrade to 64 GB with an SD card but I also want to maximize internal storage as well. I spoke with a Verizon rep who wasn't familiar with the technical details; they spoke with someone else who told them that CDMA was required but I believe that only gives you basic connectivity and not 4G connectivity.
