I had a SIM card two months ago and the SIM service was available.or the recharge service or from the service provider. The internet speed speed is also known as the best quality.Market does not have better service than Reliance, but sometimes mobile network connectivity remains weak If the network range is restored, Reliance Jia, if the mobile tower is spraded in india, top service will be done in the case of mobile Range then the top service provider will be the Reliance Jio in the market which was according to my Experience according to Best Service Provider in India.
