Lately, BlackBerry Messenger was updated to 7.0 with Voice Chat function over WiFi only. Many demanded, questioned about using the feature over mobile network which was disabled. However, the latest BlackBerry 10 OS build shows BBM has an option to enable the feature to use over Mobile Network, the question remains of what the carriers would charge for using BBM Voice. Next important question, will it be available in India? Still officially India has not received BBM 7.0.
