>>105956717It's more than just band 71, atleast it was a few years ago when I was looking at chink phones.
Can't afford to be missing bands in a rural area, for urbanites its probably less of an issue
Also band 71 is a last ditch band. If its the only band available and your device is missing it, you just won't have service.
71 isn't even used when band 2, 4 and 41 are available because its relatively low capacity, atleast on T-Mobile.
Also 4g/5g doesn't really matter here as they share the same bands. There is no falling back to 4G if you where missing 71 for example.
