I'm using the BSNL Network on my 3G mobile. The Network speed is very low. Even the the voice calls are also not connected some times. But some times it will saw that All routes are busy. And the major defect is the speed of the network is very pathentic. The speed of 3G is not good its justblike similar to the 2g speed of othet networks. And the signal may not available all the areas. The strength of the signal is very poor. The offers is also not good and the price of the package and recharge plans are also very bad. The main this the validity, they didn't provide much longer validity to the subscribers. The customerCare is treat customers like irresponsible, they agents didn't provide full information to the customer. Its has a lot of things to improve.
