If you are tired of having to switch between phones or between data networks, then this app is for you! It will allow you to do that with just one click! You can move from one phone to another and keep all your data.

This app can work in the same way as a hotspot, but it has the advantage that it is much faster and more convenient. You can make a connection within 20 meters, which is much shorter than the distance between smartphones using Bluetooth.

The data transmission is also faster than using the hotspot, because it does not need the Internet, nor the computer. You can do it without spending a cent.
