Zangi-developed SC Protocol makes Zangi the lowest data consumer messenger on the market. If your internet is expensive or if you want to save on data, you can turn on the mode called: Low Data Usage for Cellular (LTE/3G/2G) and Wifi to consume minimum data during calls. Disable this mode for highest quality calls.
With Low Data Usage mode, you can talk up to 7 minutes while using only 1 MB of Internet data. Switch on/off Low Data Usage mode from your app Settings → Low Data Usage → Enable/Disable low data with Cellular use or Wi-Fi use.
About the Streaming Control Protocol Technology
Zangi-in-house-developed Streaming Control Protocol (SCP) was designed to replace Realtime Transportation Protocol (RTP) as a standard for online data transmission. SCP works by reducing the size of the payload format in order to carry up to 25% more data in IP networks on the same bandwidth.
The advantages provided by SCP include low bandwidth usage, smart Internet channel for data transmission, fast and smart recovery for lost packages, Internet Channel Quality-Adaptive system and a fully codec-independent platform.
