Hiii friends
Today I am going to talk about a very big disadvantage of jio sim.
Realince jio only provide 4g network and this is the particular disadvantage to the users who do not have a 4g mobile. Jio sim is not supportable on 3g mobiles. If you a 3g phone you cannot use internet or calling service provided by jio. And it is very very good sim for 4g users.
