The sim has responsible for the damage of new phone who have brought a new 4G phone he take a jio sim and install in mobile then the function of the phone is going to be decrease then the phone is going to be hang.
The sim net work is very bad for the village area the only available on the market place so the mobile work in the rural area is going to be down then the people who live in the village he do not get the opportunity to get online.
This sim greater mistakes that is he release the sim for the 4g phone only so the people who have got 3g phone he do not use this sim
