I bought jio only on march. I waited it out to see the results before. The signal is not bad. I live in a village area. I get two or three bars signal in that area too. Jio has announced to improve the network soon. The customer service is good. They respond to the calls immediately. The new offer dhan dana dhan offer is good. th prime members can enjoy three months unlimited plan for just rupees 303 rupees. All voice calls are completely free to all networks. Its the best in the lot.
