CobaltBlue3 is an Android application developed by CobaltBlue Dev. that allows your PC or car navigation system to connect to mobile networks using the DUN (Dial-Up Networking) profile of Bluetooth. With CobaltBlue3, you can easily establish a wireless connection between your Android device and other devices, enabling seamless internet access on the go.

The trial version of CobaltBlue3 comes with a few limitations. It is active for only 2 days, with a maximum connection time of 10 minutes per session. Additionally, it can only be used continuously for a maximum of 2 times and does not support automatic startup.

To use CobaltBlue3 on Windows, LCP (Link Control Protocol) extensions should be disabled. The application requires Android 2.1 or higher, and rooting is not necessary.
