First think I want to say this phone is it is not 4g phone , if you want to buy to use Jio sim in it then go for another phone, but you are intrested in 3g phone then it is best in price range of 4 to 5k, best thing of this phone is its marshmallow 6.0 operating system as not given by many other major brands in even price range of 8k, camera quality is also much better in this price range 8mp rear and 5 mp front , it has 1 gb ram and 8 gb rom, that is excellent if not not game lover, now the biggest feature is its hd display, so you must go for it if your budget id under 5k
