My examples in The Flamingo Hotel in Vegas you have to connect to their wi-fi while inside the hotel. Forget about trying to work remotely there and use your 5G mobile hotspot.
At the Keseya Center in Miami ... at a recent concert there they had gates with ticket takers way out of from the front of the door. You walk up to them and they say get your ticket ready and you try but nope your ATT/TMobile/etc service is blocked you can only access getting your tickets via connecting to their wifi. My 5G worked fine until i got close to those non-ticket takers who prodded me to connected to the venue's wi-fi.
National Harbor (just outside of DC) .. inside the gaylord hotel and more so inside Burger Fi and others close by both my friend's Verizon and my ATT with full bars were blocked .. had to connect to their wifi.
Total B.S. and this stuff needs to be outlawed!!! I pay for service and if its readily available (full bars) I better have access or your paying me for time you are blocking me from using it.
