I took jio sim before 1 year. 8 months it worked well .dont know what happend but for 2 months I cant able to use my data .2 kbps is the maximum speed I got for that 2 months .i suffered a lot with this server.i talked with customer care people.but no response.i waited for 2months not change.and I finally took a decision and I changed my sim card with the same number.sim portal.i took airtel sim and it working well.jio is working good but some areas the signal not reaching .and if a group of jio users are using the sim at a time jio server will fall down . so I moved for airtel sim
