It will be interesting to see how the mobile based options drive competition. I think T-Mobile and Verizon are available in the $50-60 range at my house. At some point AT&T will have gigabit so I'll have 5 options with Starlink in beta.
I've been watching market prices for ages, spent years as a broadband reseller. I've yet to see (or read about) an instance where wireline operators considered mobile data to be meaningful competition.
That said, I think that's often used as an excuse to not invest in wired infrastructure which should be dramatically superior, but often simply isn't.
Wired monopoly-based ~50Mbps service had no meaningful competition - until wireless modest-activation ~500Mbps is individually available at comparable cost.
You haven't seen it because it wasn't here. As of a few months hence, it's here. Only reason I haven't dropped local wired service for Starlink is I get a substantial discount on the former; I'm looking for any excuse to switch.
5G is unavailable in my area, so I haven't been able to see plans. Are there data limits? Throttling after a certain amount?
