Pzzapp is the world's most efficient mobile VoIP (calls over the internet) solution in the market today. Pzzapp is the only app which enables you to call any landline or mobile, direct from your smartphone, regardless of which data network you are on. It even works on 2G!
Pzzapp is over ten times more efficient when compared to similar mobile apps (Skype, Viber, Rebtel & Nimbuzz). The majority of mobile VoIP apps are limited to WiFi networks and have considerable levels of call dropping due to the large amount of data they use. Pzzapp is different! Calls can be made anywhere in the world over any data connection: 2G, 2.5G (GPRS), 2.75G (EDGE), 3G, 3.5G (HSDPA), 3.9G (LTE), 4G, WiMAX, & WiFi
