How To Make Phone Calls Over The Internet

Earlier, we used to make phone calls from a traditional phone system. Now, with the transition of time and the advancement of technology, phone calls can be made over the internet.

What is Wi-Fi Calling?

Wi-Fi calling is VoIP calls, as it uses the internet protocol for communication. Two things are required; a mobile phone that supports Wi-Fi and a Wi-Fi connection. The call is routed through the internet by your service provider and reaches the number you are contacting.

How to enable Wi-Fi calling?

You need to enable Wi-Fi calling from your phone settings. You can enable Wi-Fi calling by tapping through these settings:

  • iOS 16: Settings > Cellular > Wi-Fi Calling
  • Android 13 (stock): Phone app > More (three dots) > Settings > Calls > Wi-Fi Calling
  • Android 11 and 12 (Samsung): Phone app > More (three dots) > Settings > Wi-Fi Calling

Most of the calls through the internet are free. Calls can be made from Android, iOS, Windows, Linux, or macOS. Calls can be made either by turning on Wi-Fi or your data package. If a call is being made using a mobile career; career charges will apply, and calls will use minutes from your mobile phone plan.

Phone calls can be made using two ways:

  • App to Phone: Paid or sometimes free calls from computers and mobiles to real telephone numbers. A VoIP service is required to connect to that physical location if you want to call a mobile phone or a landline number. The VoIP services depending on the location you are calling, charge per minute. These VoIP services also offer monthly subscription plans. Examples of apps for phones include Google Voice, Skype, and Viber.

Final Verdict

If you’re not calling a landline or mobile number, you may use Facebook’s Messenger app or WhatsApp, which is a secure alternative because a Facebook account is not required for registration.
