I have started using this jio sim from about 8-10 days.
The speed that I get for 4g is just amazing even when compared to airtel and vodafone.
That too the card is offered for free.
No one can complain about it if you get anything for free.Just love the free part.
Even the calling is free for 3 months.The call quality and voice quality is just so amazing and clear that we can hear each and every word of the speaker perfectly.This has also made the rates of other cell operators to reduce.
Love jio.
Thank you
