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.
