How to Use Two WhatsApp Accounts on Android

WhatsApp’s Multiple Accounts feature allows you to add a second account if your phone supports dual SIM or eSIM.
Open WhatsApp, go to Settings, and tap Add Account.
If the feature isn’t available in your region, Android’s Dual Apps feature or separate numbers on the WhatsApp and WhatsApp Business apps can be used.
To add a second account, you need a second phone number or SIM card, and a phone that accepts dual-SIM or eSIM.
Update the WhatsApp app to its latest version from the Google Play Store.
After adding the secondary account, all active instances of the secondary WhatsApp account will be automatically logged out, including any linked devices.
You can switch between accounts using the Switch Accounts option under the three-dot menu in the upper-right corner.
