Viber, an app that lets you make calls and send messages to your friends using your phone's WiFi or 3G connection, is finally here for Windows 8 Phone.
Cool new features
The newest version of Viber for Windows 8 Phone includes some interesting features including interactive tiles, notifications on the lock screen, group chat for up to 40 people, and the option of opening conversations from the Start menu. To start using Viber, just enter your phone number to identify yourself as a Viber user. From here, your contact list is automatically imported from contacts saved in your mobile phone that already uses Viber. Every time one of your contacts installs Viber, or you add a new contact that already uses Viber, they will automatically be added to your Viber contact list.
Use Wifi or 3G for calls
Similar to popular messaging app WhatsApp and LINE, Viber lets you make free calls, send instant messages, share photos or share your location. The quality of calls is generally good but is dependent on your connection speed and strength.
