Jio sim can work in every mobile weather it's having 4G or not or it has only 2G or 3G but on one condition, the mobile should have wifi connectivity. So that we can connect the jiofi with our mobile through hotspot. And you can access the sim which is actually in the jiofi through your phone.
In simple words if you have a jiofi, you can use your jio sim with any mobile which has wifi connectivity.
