I have used idea sim 1 years and. As My point of view idea is the worst company as in comparision to other companies. The network coverage of this network service is very poor and bad. The internet connection is very bad and very slow.If you downloading large files you can’t get the file in real time.
This is very slow network.The customer service are not also good because you ever get connected with the customer care.So many people avoid Idea and chose other sim card. The bill and charge is good but the network atrength is really matter.
