Free VoIP calling for iPod touch users

Pinger, the company behind textfree, a very popular application for iPhone and iPod Touch is venturing into Voice area by providing Free Voice calls for iPod touch users . The company already supports ad based text messages and Users have already sent more than 4 billion text messages using pinger application. The VoIP application will work on both 3G and Wi-Fi network. Pinger provides its user a unique phone number and has distributed 1.7 million phone numbers so far. Unlike text messaging, Voice calling will have a monthly cap and user needs to buy additional credit when they run out of the monthly cap.

It looks like a good deal for iPod touch users. However what is not clear is the monthly free minutes, and the per minute charge after the monthly free minutes is exhausted. At least these guys understand that giving free unlimited minutes is not gone fly from business standpoint. Many players tried free calling model and shutdown the shop. I’m not sure why advertisement is not considered for free calling instead of charging for the extra minutes. Getting a unique number for iPod and free minutes are big pluses of this application. However, Number of free minutes, call quality and per minute charge will determine the success of this app.
