WhatsApp is one of the most popular messaging apps on the planet, with over 1 billion active users. If you’re an iPhone user and you want to continue messaging your Android friends using WhatsApp, this guide will show you how to do it. First, make sure that WhatsApp is installed on your iPhone. It’s free and available in the App Store. Once it’s installed, open up the app and sign in with your Facebook account or Google account. Next, make sure that your Android phone is connected to the internet. On your iPhone, go to Settings > Messages > Send & Receive and tap on WhatsApp under “Messages.” If WhatsApp isn’t showing up here, then you’ll need to add it first. Now, on your Android phone, open up WhatsApp and sign in with the same account information that you used on your iPhone. Tap on the three lines in the top left corner of the screen (or hit Menu > Settings > Account) and select “Add Account.” Enter in your Facebook or Google login information and hit OK. Now that both accounts are set up, all of your messages will automatically sync between them! ..
