Yeah the signal strength indicator being BS (or, if we're being charitable, incomplete to the point it's misleading) is extremely frustrating. It's quite common for my iPhone to say I have full bars of LTE or even 5G, yet the data connection is unusable. There's seemingly no correlation between showing a great signal and content actually loading. I would love to see at a glance that there is no point in even trying versus spending a minute fiddling with my phone before giving up in frustration.

Yeah on Android it's easy to show what band your are connected on via one of the many cell diagnostic apps in the 'top icon' bar. If you're on LTE800/NR700 in a pretty built up area and you have no data then 99% of the time it is congestion. If you're on higher bands which have more bandwidth (though even these days 2100/2300/2600 can get pretty full) then it's less likely to be congestion.
