Reliance jio jioFi is the best device for connecting 2G Or 3G phone via wifi. AlSo reliance jiofi have a android app for android phones which is directly to connect but this one is better because jionet app only connect internet but jiofi connect Wi-Fi and also calls and messages service for free. Reliance jio is my favorite Comapacy sO they cannot disallow the error to customer. Then we can say jio stOre million of happy customer.
