Hello friend today I am talking about you Tata Docomo mobile operator . Tata Docomo which is SIM with providers Network and calling. But the rate of the calling in Docomo SIM is very very high as compared to Airtel Idea and jio. The speed of the network is also very very poor. The rate of the network is very very expensive and costly as compared to its quality and quantity. I use this sim only 6 month because it does not provide us good facility so by the time I am not using this Tata Docomo SIM.
