Cellcom was the first to market mobile phones with Hebrew language menus. Its current CEO is Nir Sztern, who was appointed on 1 January 2012. ==History== Cellcom's entry into the Israeli market caused a revolution in wireless services in the country as it offered service at rates which were a fraction of those charged by Pelephone, which until Cellcom's launch held a monopoly on cellular services in Israel. Its launch was not without problems though and during 1995, Cellcom subscribers experienced widespread service disruptions of unknown origin. After an intensive investigation the cause was finally traced to a software bug in Motorola's MicroTAC Alpha handsets – which were ubiquitous on its network at the time. Nevertheless, its attractive rates led to a huge demand for the company's services and within a few years it had accumulated over a million subscribers. As of the end of the third quarter of 2012, it had around 3.4 million customers, the largest of the Israeli mobile providers in terms of customer base size. The vast majority of active voice clients are on its GSM network while data usage is spread across networks of different technologies. The company initially operated a TDMA network nationwide in the 850 MHz band but after winning tenders for GSM-1800 frequencies it began offering GSM services. Cellcom eventually sought to replace the 850 MHz TDMA frequencies it owns with standard 900 MHz GSM frequencies but Pelephone and Partner (Orange) petitioned the Ministry of Communications to deny this for technical reasons. This put Cellcom at a disadvantage since though most of its users had converted to GSM, they were not able to make use of the lower frequency's better in-building penetration and greater cell reach. With its entry into 3G wireless services, Cellcom demonstrated the first mobile video call in Israel. Since the beginning of 2006, Cellcom has been deploying a 3G UMTS-2100 network nationwide which by the end of 2007 covered than 87% of the population. Cellcom was the first in Israel to launch an HSDPA network (also called "Generation 3.5") nationwide. In 2011, Cellcom began to deploy UMTS services in the 850 MHz band, employing unused capacity in that frequency range since it had very few TDMA customers remaining. The Israeli Ministry of Communications has approved Cellcom's plan to shut down the TDMA-850 network on 31 December 2011. In August 2014 Cellcom launched an LTE network in the 1800MHz band. In mid-2006, Cellcom received a license to offer terrestrial domestic telephony services using the national prefix 073-2. The service is mainly aimed at large businesses. The license allows for advanced wired telephony services, Internet services and high speed data transmission over its fiber optic network which is spread out throughout the country. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cellcom (Israel)」の詳細全文を読む スポンサード リンク
