Maybe I'm just fortunate. I was on the XL 16GB plan up until February when Verizon started the unlimited plan. I never noticed any change in my data speeds after the switch. I live in Austin, and my speeds are fairly consistent at around 26Mbps down and 19Mbps up. These speeds are normally the same during the day, and a bit higher at night (less network traffic I assume). I do connect via LTE band 13 most of the time, but in the suburbs I connect to band 4. I'm on the Beyond Unlimited plan, which does provide better video quality and, I've never noticed any drop in speeds.
