I'm using lenovo p2 phone. I'm getting following popup error every few seconds. It is very annoying.
My mobile data connection is on. But it is showing " Failed to connect to the network. Please check you network connection status" . I have attached the screenshot. Please help

Do you have dual sim cards? It looks like the second sim card has weak or no connection.
