In my local area, I didn't face any issue with connectivity. It's always excellent. Cellular call quality is pretty nice too.
Quality is good on 3g , average on 2g.
Con- still no volte support.
Nowadays, the internet speed on their 4g network is acceptable. Its 1Mbps on average ranging from 2Mbps during night and early morning and around 200-400 Kbps around the crucial busy hours of day.
3g internet speed had gone down and is not very compatible.
2g internet is past now and is just zero.
