No, using Bluetooth doesn't count as data usage. However, if you're using an app that accesses data while using Bluetooth, you'll use data through the app. For example, if you're listening to music on the Pandora app with wireless Bluetooth speakers, you'll be using data to access the app.
Bluetooth is a short-range wireless technology you can use to connect devices together..
For example, you can use Bluetooth to:
Make handsfree calls on a headset or in your car
Listen to music on wireless speakers
Use a wireless mouse or keyboard
Print a document in another room
Depending on the Bluetooth profiles included on the device, Bluetooth technology has the capability to wirelessly synchronize and transfer data among devices.
The exact functionality provided by a Bluetooth enabled device depends on the Bluetooth profiles included. Verizon Wireless products do not include all Bluetooth profiles.
Once you pair a Bluetooth accessory with your device, it can be used without the need for re-pairing. Contact the device manufacturer for additional Bluetooth support.
