The best way to use these kinds of apps for making online phone calls from a smartphone is to double check the call plan and make sure you don’t run up too many minutes using the app. Vonage also has an app for making online calls.

Skype and Google Voice are also available as an app for smartphones, although in most cases carriers make sure that callers still use minutes on your phone even though they are getting around paying the carrier’s international rates. Making Online Phone Calls with Smartphone Apps Google Voice is another software for making online phone calls you can dial using a keypad right from Google Chat, and quickly connect to the person you need to speak to. It’s a VOIP software that allows you to make calls to mobiles, landlines and other PCs by using your computer as a phone (you’ll need speakers and a microphone or a good headset.) Skype can also provide you with an online number (at a cost) so anyone can call you from their mobile or landline, which allows you to answer using Skype, no matter where you are, or allow the call to go to voicemail (so you can listen in later).

Skype is one of the most popular applications for making online calls.
