I started using Telenor from last 2 years and I feel its network coverage is good but the problem occurs when you go on roaming, I experienced very bad network in my hometown Kundapura near to Udupi. Even Telenor don’t have facilities of 4G/3G internet. Telenor don’t have their own towers across India and while roaming get connected to other operators network and hence charges get high. So better choose other network if you are roaming type person. Telenor is good for calls but worst for Internet.
