I hv mostly used with my mom because my mom use tata company sim for calling . bus I am very fadup this connection .there are no 3g internet network . call rates are very high .when I go to delhi because my family live in delhi thats why I go to delhi mostly .in delhi there is no network for docomo .no roaming pack applicable . every time my mobile incoming call charge verymuch . so I want to tell docomo company please provide your customer roaming in delhi ncr . and 3g internet service .and good network .
