That's not bad for the cheap plan. Even the slow mode is fast enough for video conferencing and doing basic remote work. They still have a separate unlimited plan for anyone who needs more.
I haven't done a video call on it but it does work for youtube. It's best to pause a video at the start but it buffers and plays just fine. Blocky but certainly watchable.
I had a shitty DSL line just a couple years ago before Starlink. Maybe 700KBps if I was lucky. Both me and my partner could remotely work on it, run zoom calls at the same time. That said, it is nice to have more bandwidth, but people do vastly overestimate how much they really need.
