Honestly my first connection is tata Docomoand I was going good with it. At first they provide good service and good network connectivity.. And there is lots of good offer’s they provide.. Docomo give the low rate network plans.. it makes Docomo different than other mobile operator’s. But then the network was very poor ..the network connectivity is very very poor .. when we travel to other places the sim card will be cut for a while... I can’t call or text anyone..it is totally disappointed me .. I can’t get range in outdoors.. that make me very unsatisfied.. Everyday I want to my college and travel to other places but there is no range and no network connection... I can’t call anyone.. so I hate tata Docomo .. so i switch to another one.. I am not satisfied of this network.. before you Take this network make sure that there is perfect range and network connection in your Aria...
