Jio is the most user friendly and the most helpful thing launched by anyone in the recent years.
Everything is perfect about it. High speed data, free calling and data ( I know everybody knows about it) .
Well there are some network coverage problems ( not really problems) if you are sitting in the interior of a place, the signal column shows only 1 or 2 points. But it is full if you are on road or at a open place.
The speed also slows down if we are at any major interior place but who cares until and unless everything is free.
