I BROUGHT MY NEW JIO SIM ON 2 OCTOMBER 2016 WITHOUT TAKING PERMISSION FROM MY MOM. I BROUGHT THIS BECAUSE OF IT GIVES FREE CALLS, NET, MSG. BUT IN THAT 2 MONTHS I HAVE MANY PROMBLEMS WITH JIO SIM. IN OUTSIDE OF CITY THE RANGE OF THE NETWORK BECOMES ZERO AS WELL AS WHILE IN THE CITY THEIR ARE MANY PROBLEMS REGARDING CALLS . WHILE CALLING THE PERSON YOU HAVE CALLED CAN’T HEAR YOU. ALSO THE CALL GETS DISTRACTED TO OTHER PERSON. THIS IS ALL PREVIOUS STORY. AFTER THE FREE USAGE ENDS AND THEN MIRACLE HAPPEND THE RANGE THE CALL DROPS ALL THE OTHER PROBLEMS GETS REDUCED .NOW I MAKE JIO SIM AS MY PRIMARY SIM . I HAVE CHANGED MY WHATSAPP NO. TO JIO BECAUSED NOW I HAVE GURANTE THAT JIO IS BEST. BECAUSE OF JIO ALL COMPANIES HAVE TO REDUSE THEIR CHARGES NOW THE CHARGES ARE REDUCED TO 300%. THIS IS THE GREAT WORK DONE BY JIO . I REALLY APPRETIATE WITH THAT.THANKS JIO TO MAKE MY LIFE HAPPY .
