I just spent a couple of hours on the phone with Sprint. They switched the Sprint Towers off in my area on Thursday. Since then, I was lucky to get 5Mbps if anything at all in my area.
After getting transferred through three other people, they put me through to a guy that called himself a Network Engineer. After some troubleshooting, he concluded the T-Mobile towers weren't going to work in my area for me. He switched me to their new system which is in beta that utilizes both Sprint and T-mobile towers and wow. He told me the new system was going to get even faster before they bring everyone online.
Normally, I'd get 60-70 Mbps on the old Sprint system. My fiber optic through the phone company at home suddenly seems antiquated.
