I think they are providing the best possible network connections for 4G compared to other service providers of India. I know the sim is taking much time to be activated. But, we should consider that how much people are buying the jio sim so the process is slow. We should be patient. They are also giving us very cheap plans of 4g internet. This is the reason for steep decrease of prices of other rival companies.
I recommend you should go for it if you have 4G phone.
