Cellcom 4.63

Cellcom is an Israeli telecommunications company. Founded in 1994, most of the company's business is centered on wireless service. Its current CEO is Nir Sztern, who was appointed on 1 January 2012. As of June 2016, Cellcom had 2.812 million subscribers.HistoryCellcom'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..NetworkCellcom initially operated a TDMA network nationwide in the 850 MHz band but after winning tenders for GSM-1800 frequencies it began offering GSM services, and eventually sought to replace the 850 MHz TDMA frequencies it owns with standard 900 MHz GSM frequencies but Pelephone and Partner 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.
