I am using this network from about 6 months. But the network service is not so good. In punjab region the signals are quite good. But in another region like haryana HP and delhi the signal strength is very bad. And these region your mobile number is always out of coverage area. And you are also not able to make calls because of no network service. Plan are quite good but the internet consumption is so high. 3g speed is very good. But today is the time of 4g network. I will port my number from docomo to another 4g network soon
