Use 2 Whatsapp Accounts on a Single/Dual SIM Phone
  OGWhatsApp            DOWNLOAD       Once you install OGWhatsApp  on your Android device, the app allows you to use two different telephone numbers with WhatsApp from the same smartphone.   It´s much easier to install OGWhatsApp  than it might seem at first. You just have to follow these three steps:   -The first step is to make a backup copy of all of your messages (if you  want to save them) and then delete all of the user information for the  app (or you can just reinstall the app)   -The second step is to rename the /sdcard/WhatsApp directory to  /sdcard/OGWhatsApp. You can do this using any file manager for Android,  though it is easier to do this from Windows.   -The third and last step is to verify your old number in the OG version  of WhatsApp, and then verify your new number in the normal version of  WhatsApp. That's it.   OGWhatsApp  is a very useful tool for users who want to have two WhatsApp telephone numbers on their Android device.       Images of OGWhatsApp  ...
