Its not bad in entire hyderabad. Some crowded places like gachibowli, Madhapur etc are getting very less speeds. My home is literally center of Hyderabad and I get 15mbps always. But yes, network is way too good at outskirts... I have checked at 2 places. got 30-40 mbps at Uppal and 70 mbps at Hyderabad - Karimnagar Highway - 50 kms from my place
