Idea is not very good if someone is looking for a sim card for both calling and browsing internet. Internet service is very bad from this operator, the rates are very high and the speed provided under the high rates is very slow. Other facilities like calling and other offers are fine. The only advertise about their idea 3G being the best but is not so. The speed really is frustrating sometimes. There is a network issue too sometimes but rarely(only at some places).
