The only thing you need is an internet connection. With apps available on the app stores, it is possible to make free voice and video calls without relying on having a cellular plan on your phone or computer. Old-fashioned cellular network-based phone calls still exist, but when you compare them with Wi-Fi calls, we may even assume that they will be history in the near future.
Talking on the phone using the internet and on top of that, seeing that person on the screen weren’t something people would imagine a half-century ago, apart from science-fiction stories. There were times when the internet wasn’t available anywhere, and people used just regular cellular calling methods.
The advances in technology make it possible to connect with anyone and anywhere in the world.
