I am using tata docomo number from last 7 years. earlier it as indicom but then I switched it to docomo. and I am contuining the same number for 7 long years. all the schemes are really good network is also available alost everywhere. data services are also good. even 2g speed is also fine then others. I am really satisfied with the services and hence continuing on the same network.
but sometimes bal is deducted unnecessarily by activating some services. but they refund the amount if we contact customer care
