lly, the government determines MNOs and controls the number of MNOs. However, government does not interfere in the management of oper- ators since all of them are private companies. In 2008 June, a bill for MVNO was passed. Accordingly, though there was no MVNO launching business till then, more effective competition was to be expected in the future. The major role of the government changed into being a strategic player from a ruler.

There are two reasons for this change in the attitude of government toward the mobile communication industry.

GPRS (General Packet Radio Service), EDGE (Enhanced Data GSM Environment), CDMA 1X, CDMA EV-DO, CDMA EV-DO Rev. A, WCDMA, and HSDPA were adopted. The CDMA EV-DO and EV-DO Revision A networks of CDMA operators (Verizon Wireless and Sprint Nextel) covered 82% of the U.S. popu- lation, and WCDMA/HSDPA networks of GSM/TDMA operators (AT&T and T-Mobile) covered 43% [4]. Some SPs committed to deploying the WiMAX networks. While the basic data services like SMS began to be available at the end of the 1990s, the SPs paid more attention to voice services and marketed data services primarily as and add-on to voice services in the following years. The quality and price of voice service ha
