VoIP and an instant messaging app for exchanging media messages
Those who are familiar with the popular communications app called Skype will easily understand Viber, which is quite similar in both functionality and appeal. The app is designed to let users make free internet calls and send free text messages over the internet. The only requirement is access to an internet connection.
Viber has a user interface that is incredibly intuitive and provides many features that are unique to the platform. Users can send photos, text, video, voice, and even locations. Text messages have emoji compatibility, and users can tag items with specific info or stickers to make them more shareable. New stickers can be purchased in the sticker store to let users customize their conversations even further.
Once you've downloaded Viber on your Android smartphone, you can allow it to access the list of contacts saved to your device. The app will populate with the contact list so you don't have to manually enter the information yourself. The audio quality is surprisingly adequate considering it uses nothing but an internet connection.
While the app can function using a data plan on the phone, it is preferable to use WiFi since certain features of the app can use more data than simply calling over the network. Users might want to consider limiting the app to 3G data usage if using the network data is required.
Users will also enjoy the fact that the app, much like Skype, can be downloaded on both Mac and Windows PC. That means the same account can be used through multiple devices, so conversations can be continued from the computer to the smartphone.

Potentially dangerous permissions
- ACCESS_COARSE_LOCATION: Allows an app to access approximate location. Alternatively, you might want ACCESS_FINE_LOCATION.
- ACCESS_FINE_LOCATION: Allows an app to access precise location. Alternatively, you might want ACCESS_COARSE_LOCATION.
- CALL_PHONE: Allows an application to initiate a phone call without going through the Dialer user interface for the user to confirm the call.

- READ_EXTERNAL_STORAGE: Allows an application to read from external storage.
- READ_PHONE_STATE: Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.
- READ_SMS: Allows an application to read SMS messages.
- RECEIVE_SMS: Allows an application to receive SMS messages.
- RECORD_AUDIO: Allows an application to record audio.

- WRITE_CALL_LOG: Allows an application to write (but not read) the user's call log data.

- ACCESS_WIFI_STATE: Allows applications to access information about Wi-Fi networks.
- BLUETOOTH: Allows applications to connect to paired bluetooth devices.
- BLUETOOTH_ADMIN: Allows applications to discover and pair bluetooth devices.
- BROADCAST_STICKY: Allows an application to broadcast sticky intents. These are broadcasts whose data is held by the system after being finished, so that clients can quickly retrieve that data without having to wait for the next broadcast.
- CHANGE_NETWORK_STATE: Allows applications to change network connectivity state.
- DISABLE_KEYGUARD: Allows applications to disable the keyguard if it is not secure.

- READ_SYNC_SETTINGS: Allows applications to read the sync settings.
- READ_SYNC_STATS: Allows applications to read the sync stats.
- RECEIVE_BOOT_COMPLETED: Allows an application to receive the ACTION_BOOT_COMPLETED that is broadcast after the system finishes booting. If you don't request this permission, you will not receive the broadcast at that time. Though holding this permission does not have any security implications, it can have a negative impact on the user experience by increasing the amount of time it takes the system to start and allowing applications to have themselves running without the user being aware of them. As such, you must explicitly declare your use of this facility to make that visible to the user.
