Like what? I remember having a 3G iPhone and actively looking forward to 4G because bandwidth actually limited certain tasks. Since 4G has become widespread, I've never felt that way. The only time I notice my phone's finite bandwidth is when buildings are blocking my signal, which will only be more prevalent with 5G because millimeter waves can't penetrate materials.
There is literally no media that my device makes use of that it can't download in a comfortable amount of time. With modern compression technology, even streaming HD video is basically seamless over cell towers. Years ago I was able to play online games by tethering my Xbox to my phone. I just don't have a use for more bandwidth.
