OP is written by LINE employee, that's widely used messenger in some Asia. So it seems that it covers wide user range. Maybe Asia is good at 4G deployment, some developing country just skip 3G and deploy 4G. Or OP maybe only see Japan, where 4G coverage is enough high to stop supporting 3G on 5G phone.
