I live in Nashville, which has pretty good 4G coverage, but am getting terrible download speeds of .59Mbps or less during business hours. Around 5:30, the speeds will creep up and by 6:30, they're pretty fast (last test was 5.99Mbps). The increased speed at night does me no good, as I use my wireless connection when I get home. Verizon C/S worked with me a few weeks ago and determined it was my phone, and sent a replacement, but I've seen no improvement with the new unit. Very frustrating to pay such a premium for the data plan, when it's virtually unusable during the day.....so much so, that often, Speedtest.net cannot finish testing upload speeds due to poor speed. I almost always show 4 bars, so I'm at a loss at how this can be happening.
