Does it cost money to send things by Bluetooth?

Bluetooth is free to send things, but two mobile phones need Bluetooth function at the same time to send data information to each other. The method of sending data information via Bluetooth is as follows:

1. Turn on Bluetooth on two mobile phones at the same time, so that the Bluetooth pairing of the two mobile phones is successful.

2. Select File Management on one of the mobile phones.

3. After entering file management, find something to send, such as software package or picture, and press and hold the software package or picture to send.

4. Select Send in the pop-up menu, and then select Send via Bluetooth.

5. Another mobile phone can choose to receive.
