To make prank call you need to have a android device or its emulator like Bluestack which is a computer software.
1. You have to download Voxox on your Android device and install it.
2. After downloading it you need to sign up.
3. After sign up you will see a window at the upper right corner of this window you can see a option more click on it.
4. After clicking scroll down and find user option and click on it.
5. After that click on user id and and erase the number written in it and replace it with the number that you want the receiver to see.
6. After that call the anyone using Voxox and hey its done
Note – I recommend you to only use Voxox for giving Misscalls because in this app you will get 1 dollar free talktime after that you will be charged.
