I am sorry to say the mobile operator idea company is the best company but now a days they are not giving much better service and its network is very bad because that when I call to customer care they told that it will work when u restart the phone and when I have restarted the same problem happend but I have call next time and they told that it is the maintenance update is going on and it will work in 2 to 3 hours after so it is bad operator
