Viber allows you to communicate with your contacts via text message, without paying SMS charges.
What does Viber do?
Viber allows you to use your real phone number to communicate with other Viber users. The app scans your phone book and adds contacts that use the service to your lists, allowing you to chat with them outside of your normal network, using mobile data.
While other versions of the app (for iPhone and Android, for example) allow for phone calls, Viber on Nokia S40 only supports messaging and picture sharing. There's also a feature that allows you share your location through the app based on your GPS positioning.
Viber for S40 supports group chat, allowing you to exchange text messages with up to 15 people at the same time.
Is it easy to use?
The interface of the Viber app for Nokia phones is compact and easy to get around. Contacts are displayed in a neat list and you can easily see all your recent chats, including the start of the last thing that was said in each case. Menu options are neatly housed at the bottom of the screen.
A cheaper alternative
Although it lacks voice calling support, Viber for S40 makes a cheaper alternative to using SMS and MMS on your phone.
