Jio is the brand that changed indian way of using internet. But it's also true that many are dissatisfied with it . Jio only has limited amount of network tower's which has too many users . I used jio before and it was alright but after I changed where I live it didn't even give full network so internet speed is not even a thing.
Jio is only expanding but not satisfying customer's by giving them more network in one area and by having 1 network take the load of thousands of customers the network doesn't give anybody a good enough speed.
