Telenor is not a good network operator . yeah the call rates are low but it is too slow sim . if we compare other network operator with it then the time at which other operator overs the download there uninor starts the download .
Wyen we dail calls it takes 5-6 seconds to connect .
And at many places it doest get network coverage also.Inspite of you should buy jio sim becaose it is too fast and no other operator can compare with it
