Blackberry was one cellular company which wasn’t offering a mobile VoIP app compared to its other competitors like iPhone, Android and Symbian. However, today things might change thanks to the Indian VoIP setup based in Bangalore, who has introduced a new VoIP application for Blackberry OS that can make calls over Wi-Fi known as TringMe . It allows multi functioning as with a single-click, you could have worldwide conference calling, and when there’s no Wi-Fi, it can switch to the local-access number/callback over the cellular network. Therfore, life for Blackberry users is no more going to be difficult as now you could download your own and get started with the calling.
