Hello gyes, I have been using idea sim since fifteen days. I have bought it just 320 rupees with a velidity of 84 days and the benifits are daily 1gb internet and unlimited call. Thoug call is not unlimited but it’s enough. these are the benifits but main thing is it’s speed. ! The speed is really fantastic. It has a very good speed, aproxymately 3mbps download speed and also upload speed. And also there is no network issue in this mobile operator. Though somewhere it show network issue but that doesn’t a big matter. From my opinion Idea is a good mobile operator. Thanks.
