I am from Samalkha, New Delhi and I use Bsnl as sim for my mobile. it provide high speed when the network is HSPA. Bsnl is a good service providers and also good network quality.
Bsnl 2G net speed so good and 3G speed very faster than that others operators. The best advantages of bsnl 3g is that it provide 3G packs at the very lowest rate. Customers care service very good. I go to anywhere Bsnl networks available very place.
