Taking lessons from the Mumbai train blasts a month ago where Mobile network were clogged during emergency, leading cellular companies have now joined hands to make their networks interoperable with each other during times of crises.

This new model which has been introduced by Airtel, Hutch and Idea Cellular is currently in place in Surat which has been experiencing severe floods.

The three operators have entered into an agreement to share the traffic load between them. So a call from an Airtel subscriber could be automatically routed through the network of Hutch or Idea depending on which network is less congested in a given area.
