Most smartphones have two SIM cards, and this is one of the reasons that encouraged people to search for how to have two WhatsApp in one phone. The thing is you can’t download the official WhatsApp twice on your phone, but there is more than one way to have two WhatsApp with different phone numbers on your phone whether it is Android or iPhone.
There is more than one method to get a second whatsapp on your phone:
The first method is to download WhatsApp official from the App Store or Google Play, and then download WhatsApp business. This method is perfect for Android or iPhone users because you won’t need to download from unknown resources.
WhatsApp Business is the same as the official WhatsApp with additional features for business owners.
Download the official WhatsApp from Google play, then download one copy of WhatsApp Plus. We recommend GBWhatsApp Pro, WhatsApp Gold, or WhatsApp iPhone for Android.
You can download any copy of WhatsApp Plus, just make sure you are using a different mobile number.
On iPhone, you can download the official WhatsApp and WhatsApp Plus iOS, but have in mind that if the IPA stores are not working then WhatsApp Plus on iPhone will not work.
This method works only on Android devices. Some WA Plus copies support activating more than one mobile number on the same WhatsApp, such as KBWhatsApp.
In the main interface, there is an icon to add accounts, click on it to add a second phone number.
Make sure you back up chats before you add another account. You can add up to 5 accounts (different phone numbers).
