In late 2006, the ETC signed an agreement worth US$1.5 billion with three Chinese companies, ZTE Corporation, Huawei Technologies and the Chinese International Telecommunication Construction Corporation, to upgrade and expand Ethiopian telecommunications services. This agreement will increase the number of mobile services from 1.5 million to 7 million, land line telephone services from 1 million to 4 million, and expansion of the fibre optic network, from the present 4,000 kilometers to 10,000 by 2010. It is part of a larger US$2.4 billion plan by the Ethiopian government to improve the country's telecommunications infrastructure. In 2018, the mobile service business has reached 85% of the country. In February 2018, it was reported that Ethio Telecom had 64.4 million subscribers making it the largest telecommunication services operator in the continent. The operator runs three terrestrial fiber optic cables with a capacity of 42 Gbit/s to connect Ethiopia to the rest of the world via Kenya, Djibouti and Sudan. In August 2019, the company announced that it will install 4G network before other telecom companies enter the Ethiopian market since the government decided that it will liberalize the telecom sector.
