Hii guys, I am using jio sim from last two mounths it have a lot of good 4g speed but it also have a lot of call drops generally 80 calls out of100 will be droped. Now it also have a limit of downloding in a day that is 4GB/day. After using this speed it becomes a speed of 128kb/sec speed of 2G. It works only on 4g handset.
