Trying to decide between the many Android VOIP apps that are available can leave you with more questions than answers.
How do I know which one is right?
Do I have to pay a monthly fee?
What are the features of the best apps on the market?
All of these questions are valid ones and should be answered before you choose the app to use. When you make calls over VOIP you will either pay per call or sign up for a monthly plan. It is best if you know that you are using the service that is most cost effective for you.
