Reliance jio luanched a low budget smartphone.The price of the jio phone is low also its performance very low.Jio sim network is good but the connectivity of this phone is very poor.Poor network connectivity.When I use internet on this phone it will be very heated and function will be slow.So it is a low standard less featured phone.And also it will charge 153 rupees per month to unlimited call for 29days and gives 2gb data valid for 28days.Mobile functions are very slow and battery backup time is too low.
