The company promised to enable the U1 chip in iOS 13.1. After updating the iPhone 11, we tried to transfer the file via AirDrop to the iPhone 11 Pro Max, but we did not have a new smartphone search interface.
Changing the region and connecting the American Apple ID did not help.
Judging by the information on the Apple website, U1 is disabled in Belarus, Ukraine and Kazakhstan.
The U1 chip uses ultra-wide band (UWB) technology to search for devices nearby.
If you want share an AirDrop file with someone, just point your iPhone to this device and it will be the first on the list.

Example of U1 working in iPhone 11:
So I got the new AirDrop thing to work, it’s really good at finding the other device’s position, but it only says “raise phone ”And does nothing after that. pic.twitter.com/XK0VB3e1YR/p

In this case, the chip works, but cannot find other iPhones because they are tied to one iCloud account.
What is the reason for the regional restriction is unknown. The Apple site could not find the answer to this question.
