I recently taken the sim and I have to say the experience is very bad.for activating the sim they take so much of time almost 10 days.they are saying your details are not updated in the system and asked me to call after six hours.but they told only these things for 10 days and atlast my sim is activated and here new problem started that is they without my permission activating callertunes and other services.such a fraud company I dont like this.
