gTalk is a mobile app for Android. The gTalk helps users make international calls easier from an Android phone. The application is free to download.
After downloading and installing the gTalk, open the application and follow the simple wizard to set-up the gTalk:
VoIP Calls via Wifi, 3G / 4G, edge or UMTS.
You will just need to select the Contact you want to call or enter the number manually in the DialPad. The gTalk will take it from here.
The same gTalk low rates for international calling apply if you use the gTalk.
If a data connection is available the application might require a minimum amount of data traffic to update from time to time.
