Internetcalls Wifi Dialer is a free Android app developed by Finarea in the Social & Communication category. This app enables you to save up to 80% on your monthly calling charges by making cheap or even free international calls through WiFi or 3G networks. You can select any contact from your regular contact list or add new contacts. In addition, if you are already an Internetcalls user, you can import your contacts from your Internetcalls client as well.

To start using the app, you need to follow three simple steps. First, download the free Internetcalls dialer app. Second, register a username or log in using your existing credentials. Finally, buy some credits. If you buy 10 euro credit, you'll get the first 120 days of calls to selected destinations for free. You'll only start using your bought credit after these 120 days have expired. You can also use your credit for any calls to non-free destinations, including those which aren't free.

It's a great app for those looking to save money on international calls. However, using the app as a default dialer may interfere with dialing 911 emergency services.
