WhatsApp is one of the most popular messaging apps in the world. It’s available on both Android and iOS devices, and it has a large user base.

Tap the three lines in the top left corner of the screen, then tap New Account. Enter your phone number and email address, then tap Next. To use your old account on another phone, open WhatsApp on that phone and sign in. Tap the three lines in the top left corner of the screen, then tap My Accounts. Scroll down until you see your old account name and tap it to open it. Enter your password if necessary, then tap Log In. ..
