Got it free from nearest relaience digital store .
As of now it offers free net upto 4gb Until Dec 31st.
It calls jio as 4g but the speed is more like 3g in day time. Yes net speed gets fluctuated from place to place and time to time.
But early mornings and late nights The speed is awesome.
Download speed is good upload is OK OK.
Calls do not connect easily, we need to keep struggling to get call connect. Even if call gets connect it drops after some time.
Until now there is no issue with signal.
I'm using jio as my secondary sim in sim slot 1 that is jio, it is blocking my primary sim in slot 2 airtel . I got complaints from my friends that my primary number is not connecting.
I'm sure relaience will fix these issue very soon.
Jio offering free net so go for it.
After Dec 31st if you like the tarrif plans stay withit.
If not you can go for other network. Thank you.
