Is jio is is providing free Internet facility to everybody but it has 1 problem that its work only in 4 g phones only we cannot even call or receive call if our phone does not have a facility are vo LTE feature because we transfer the signal of LTE into voice we have to use jio voice app for making call and receiving call and in 3 G phones and 2G phones we cannot even use the jio Sim so how can we use the free Internet or anything else provided by jio company so the company introduced the jiofi product so that it could provide the facility of Internet to every phone either it is 2G or 3 G phone
