There are several differences between the two: 1. You need internet access to make a WhatsApp call. Unlike regular calls, WhatsApp calls are routed through the internet. This means both you and the recipient must be online. 2. You need a smartphone to use WhatsApp. If you want to make a regular call, you can use any mobile or a landline phone. However, if you want to use WhatsApp and make calls through it, both you and the recipient must do it on a smartphone. You won’t be able to install the app otherwise. 3. WhatsApp calls are free, subject to data charges. 4. If you have a poor internet connection, you might have trouble establishing a connection on WhatsApp. Regular cellphone calls do not depend on your internet connection. 5. WhatsApp international calls – it doesn’t matter if you’re calling the person next to you or someone on the other side of the world. With regular calls, you may have to worry about international calling rates. 6. Higher security with WhatsApp calls. WhatsApp’s end-to-end encryption covers messages, phone, and video calls. The app scrambles the data extracted from your phone, which others will need a code to unscramble. As such, no one else can eavesdrop on your conversations or look at your messages. 7. You can’t call a landline phone with WhatsApp. If you’re trying to call someone via WhatsApp, you should know that you’re only able to call people who have the app. That means you can’t call landlines or any other cell phones that don’t have WhatsApp installed. 8. You can make a video call with WhatsApp. Unlike regular calls, you can choose between a phone and a video call in WhatsApp. You may prefer the latter when calling certain people. As you can see, regular calls and WhatsApp calls are different in many ways. Even though you can live without either of those, it’s recommended to have access to both.
