Cellcom operates a 5G network (shared with Golan Telecom, WeCom, Walla Mobile), along with OTT service called Cellcom TV, IPTel landline service, international dialing service (013), and acts as one of the billing agencies for electrical power in Israel.
Cellcom 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.
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 by then 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 1800 MHz band.
