The story with mobile phone makers are not different from the mobile phone carriers, in most of the cases the mobile phone manufacturers launch a handset in collaboration with a certain network and provide gifts and benefits on the purchase of their handset from a specific network. For example, Nokia N71 is launched in collaboration with Orange network and then Orange, to attract the customers will give away discounts on the price and free services on the purchase of the N71. This marketing strategy is working productively in the mobile phone market and attracting a lot of users who are interested in buying a mobile phone.
