Jio is first company in india who launch 4g network [a high speed internet, for todays generation] and most impotant think is they sell free, today they launch free internet and voice in all over the india FREE.And that is TRuE . But I must have to say this they fail to surve 4g speed to us even some time I cant send my whatsapp msgs [isnt it funny ! ] If we talk about his network then I give full marks jio is available for u at any point [as per my porsonel observation]. Even there plan is not that much costly so u can buy jio without any doubt.
