This application is useful for dual-SIM devices having data plan active on both the SIMs. This app helps you to switch data between two networks. You can set one of the networks as a Primary Network and provide some duration value for data check interval and save the preferences. A Data Check Service would be started in background which checks for availability of the networks. If primary network goes down the mobile data will be automatically switch to another network. Once the primary network is available again the data will be switched back to the primary network. You may prefer to keep the service off and use Switch Now functionality to switch the network manually anytime. This is primarily developed and tested with Karbonn mobiles available in India and may not work on other phones.
