netTALK has just introduced a new Android app that lets Canadian users call family and friends around the world with just their email address. All users just need to share the app with friends. You can also receive unlimited free calls from loved ones through a free Canadian phone number and save around 30% to 40% on international calls with the app. Payment is through Google Wallet or have it charged to your cellular phone bill. You can connect through Wi-Fi, 4G, or 3G with the app.
