Yes Lenovo a6000 is supporting jio sim card. When I using micromax nitro 2 reliance jio sim is launched, but my handset( micromax nitro 2) is not available 4g. Then iam purchased Lenovo 6000 because of this handsets features better than jio lyf mobile. After 1 months my Lenovo 6000 is was provided there main issues. Handset is too hang and decreasing mobile charge in short time. This is not eligible for friendly use. If you need mobile for friendly use then don’t purchase Lenovo a6000. The speakers are good because of Dolby. Features is not enough for Rs.85000. So this is not valuable for money.
