Instead bsnl should speed-up 4g launch. In my area it shows H+ but the speed is less than 2g n not showing any thing in speed test. In my opinion bsnl has robust infra but many corrupt officers spoiling. Now the tower maintenance and operation is done by out sourcing. These contract maintenance and operation group is simply corrupted by private operators. The senior offficial of bsnl also aware of this and they also part of corruption.
