Not all frequencies work in all regions, due to multitude of ITU restrictions on certain bands in certain areas. No. 2 band is most likely to work in most places, but not "everywhere on earth".
On non-Apple side The first chip to offer connection for 1-2 is Qualcomm Snapdragon 8 Gen 2 (with the proper antenna, modem software and manufacturer settings). Most Snapdragon 8Gen2 don't have this.
The first phones to openly guarantee support for 1-2 came out in 2024 (some Huawei, BKK phones, Google Pixel 9 series).
So "All" is a very tiny sub-population of smartphone users. Of course, this will grow, as people upgrade their phones.
Again the headlines are wrong.
