Whola lets you place calls through internet connection (3G data plan or WiFi) of your smartphone rather than through your cellphone carrier network. This easy-to-use VoIP application gives you great cost savings on international calls, exceptional voice quality.
How easy is it to use.
Very easy! There are no PINs or access numbers to remember, or SIM cards to switch. Just download the app, sign up for an account, and call your friends and family around the world right from the application. It will automatically route the call through VoIP, rather than your cell phone carrier’s network.
