With the prevalence of smartphones, chances are that a good number of your contacts already are on WhatsApp. So if your carrier does not support HD calls yet, WhatsApp calls is the way to get that. WhatsApp calls use the internet and not your carrier’s network infrastructure.

You can comfortably make and receive calls without worrying about international calling rates. Depending on your carrier’s rates this might vary but there’s no escaping that WhatsApp calls are cheaper than normal calls.Īs long as the person you want to call is online on WhatsApp, geographical locations are irrelevant. So if you’re on 3G or 4G, that’s the rate for you. The call quality on 3G networks is decent but on 2G, there is a considerable amount of lag. That said, As per calculations made by the Indian Express, a minute of WhatsApp call costs around 0.15 MB to 0.20 MB of 3G data which means a 5-minute call costs around 1MB of 3G data. Yes, the platform itself is free but you need to account for the data you will need to access and use the platform. Advantages of VoIP and WhatsApp CallsĪ lot of people like to say WhatsApp calls are free but I don’t think this is entirely true. WhatsApp relies on low latency internet and deploys VoIP (Voice Over Internet Protocol) which, simply stated, means using the Internet to make and receive telephone calls- hence WhatsApp Call. Services like WhatsApp already use the internet to carry your images, videos, voice notes between you and your chats. The internet has been around for a while and it has come a really long way.

It is important to note that the fundamental telephone technology has barely changed since the 19th Century.
