Looking for a free international calling app? Then trytextnow.com which offers a FREE USA number along with free calling features available for both mobile and desktop. This tutorial however is on making unlimited calls using a PC and Wi-Fi connections.

This possibly is the easiest and free way to call someone with a valid USA number. You can make unlimited calls to many countries (check textnow for details) which includes the USA, Canada, Germany, Brazil, Mexico, and many more. However, please note that the textnow policies might change in the future this means the free calls currently may not be available in the upcoming days.

Also, the free USA number provided by textnow can only be retained if you use the app regularly, if not, this number will be given to someone else. Anyway, hope this lesson is helpful.

Happy free calling!
