Recently I bought Lyf wind 3 to use jio sim.
Pros:
Looks and Design.
It will be useful only as hotspot. We cannot use it as primary mobile.
Cons:
Sound reception is low.
Touch is not sensitive.
It lags if you open 2 or 3 apps at the same time.
Its a cheap chinese phone.
I am getting battery backup up to evening only.
On paper, it has good features, But practically functioning is not satsfactory
Not value for money.
Cnclusion:
If you want to use Jio offer, go for lowest priced LYF mobile.
