Guys from when jio has launched it's free offer ,that may be welcome offer or happy new year offer ....
Jio has given chance to use it's sim only to 4g users ..
So only 4g users can use this ...
You can't use jio by changing some settings in your device .
Your can use jio 4g speed if you have 3g or 2g handset than only by hotspot
Thats its
