As reliance jio it offer free services but to get sim is like getting in war zone .If u mAnasultange a sim than a network issue as tower goes and come it make phone battery down than go to charge phone as the speed is considered it also a bull sh* t .
Some time it mAnasultange to get speed of 2mbps @ and every time it run in a speed of 150 to 560 kbps .
The free call offer by is also not good as sometime we get worst quality and some time call doesnot connect also.
The most suffering is that it free with some pain & wories
Jio sim make almost every phone heater as winter come we all need jio sim in phone to keep us hot in winter
