I have been using jio sim for about 2 months
Cons: The speed is just averge in this sim its not up to mark of 4g
The calling is just bullshit it says that the operators are buzy when we call anyone
The speed of data is just upto 4 gb data when we utlize the 4 gb data the speed becomes like turtle
Pros: The downloading speed of this sim from google playstore is good enough
The best part of this sim is unlimited data for 3 monts
The jio company has also launched its wifi modem for 2000 rupee( india) it convert your jio sim network into wifi
It activates within 3 days
The customer support is very good
