You can use Bluetooth without internet access. Bluetooth is a wireless technology that allows two devices to communicate with each other over a short distance, typically up to 30 feet (10 meters), without the need for an internet connection. Bluetooth works by creating a personal area network (PAN) between two devices, allowing them to transfer data, such as files or audio, between each other.
Some Bluetooth devices, such as wireless headphones or speakers, may require an internet connection to access certain features or content, such as music streaming services. However, the basic Bluetooth functionality of connecting and transmitting data between devices does not require internet access.
