Leveraging the power of the U1 chip, iPhones are able to locate and communicate with each other.
The chip uses extremely low energy for both short-range and high-band communications.
Though there is a lot to like about the ultraband, it does raise privacy concerns.
Due mainly to this very reason, some countries have banned the U1 chip.
Keeping it forever disabled can cause internet-related issues on your iOS equipment.
However, a hidden setting does exist to let you take control of the chip.
Else, it will impact the performance of Wi-Fi and Bluetooth on your unit.
