First thing I would like to say about idea 4g is its annoying ad that show all the time. We know they spending crores for those ads. Why can’t idea spent those crores in something that is worth will helps to get proper network coverage.
I don’t know how that 4g getting coverage all over india. I am from rajasthan , living. In a city pali one of the city where 4g came first my home is situated from 1km where the tower is placed. But still we don’t get the reliable 4g range.
