NEW DELHI: Vodafone India, the country's second largest telecom operator, has rolled out WiFi offload application, which will shift data traffic away from the cellular network and help decongest it. 

The move comes amid rising subscriber complaints about inconsistent data speeds over the cellular network, with 3G dropping to 2G speed frequently as mobile internet usage surges in India. 

Vodafone WiFi Connect is available on Android and iOS platforms and requires a onetime sign-in. It will come into effect anytime the user enters Vodafone's WiFi zones in Delhi and Mumbai. It has about 100 such zones in total.
