I don't know how that 4g girl gets network coverage in some remote village but me on the other hand in living in the city get very low and sometimes no network converage at all.
They are charging 255/- for 3g internet I did recharge it but most of the time it was not at all working. Airtel used to be my favourite network but now it is slowly eradicating its quality. I hope they work on this issue and resolve this as soon as possible.
