This has been brought up a few times, but I'm starting a new one so that people do not think this problem was resolved last year.
I have service that is adequate during the morning. I can do all the things I need on my phone (FB, IG, Snap, YouTube, stream songs/podcasts, view/send photos stored on the cloud, etc.) but as soon as it's lunch time (around 11 AM and later), the signal shows 2-3 bars, but the actual speeds are very very slow. Not even usually half a Mbps. And that's when my Speedtest app can detect a signal. This isn't enough to stream YouTube or even scroll facebook. Sometimes 3 or 4 text messgages come in at the exact same minute later in the afternoon. Something is either stealing all the bandwidth or Verizon can't support 61550.
