Once you install OGWhatsApp on your Android device, the app allows you to use two different telephone numbers with WhatsApp from the same smartphone.
The app itself actually walks you through this, so you’re not just guessing at what to do.Next up, all you really need to do is have your old number verified by the service, and the app itself will give you your new number. The overall function of the phone doesn’t change at all.
It will ring like it always does, and you can use all the features as you always have. The only tangible difference is that people can contact that same phone from both numbers, allowing you to keep better track of how your number is distributed.
