Overview
Tusass is a Greenlandic postal and telecommunications company headquartered in Nuuk. Its business traces its institutional history to postal and telecommunications operations established in Greenland in 1879, while the present combined company was formed in 1997 through the merger of TELE Greenland and Kalaallit Allakkeriviat, Greenland's postal service. The postal business became POST Greenland, and the combined organization was commonly known as TELE-POST until it adopted the Tusass brand in 2021. The name is derived from Greenlandic slang meaning roughly “talk to you later.” Tusass operates in a market shaped by Greenland's enormous territory, small and dispersed population, severe climate and limited transport infrastructure. It has a licensed monopoly over most telecommunications services in Greenland and serves cities, towns and remote settlements through a mixture of submarine cable, terrestrial radio links, satellite systems and mobile networks. Its telecommunications role is therefore not limited to conventional consumer connectivity: the company operates infrastructure that is essential to linking communities across the island and to connecting Greenland with the wider internet and global communications systems. The company is organized around three broad areas: postal services, commercial services and IT services. Its postal activities cover mail-related operations, while its commercial telecommunications portfolio includes mobile voice, mobile data, broadband and related connectivity. Tusass also provides business and information-technology services. It manages Greenland's country-code top-level domain, .gl, and operates the Greenland Connect submarine cable system, together with the Greenland Connect North extension. These assets support higher-capacity connectivity for communities connected to cable landing points and feed into terrestrial radio infrastructure serving additional locations. Tusass's mobile network developed from GSM services launched in 1998 in Nuuk, Ilulissat, Kangerlussuaq and Sisimiut. Third-generation development followed through a 2009 network project, and 4G service began in Nuuk in December 2013 before expanding to other major communities. A later modernization program with Ericsson was associated with the company's “Mobile First” strategy, which sought to extend high-speed mobile internet more broadly across Greenland. Tusass selected Ericsson to build a 5G network in 2019. In February 2025 the company launched Voice over LTE and announced plans to retire older network generations, with 3G scheduled to cease in 2026 and 2G expected to remain available until 2027. Fixed landline connections were closed in 2022 as customers were moved to mobile alternatives. Internet access is delivered through several technologies. Submarine-cable-connected communities have benefited from Greenland Connect and Greenland Connect North upgrades, including VDSL services introduced in 2017. Tusass also operates a long radio-chain network linking cable infrastructure with communities beyond cable landing points. Satellite connectivity remains important in remote areas, including farms and far-northern settlements. Ground stations completed in Tasiilaq in 2020 and Ittoqqortoormiit in 2021 enabled flat-rate broadband in those locations, while a later satellite transition to Amazonas Nexus, marketed by Tusass as GreenSAT, supported connectivity for remote locations and Qaanaaq. The Tusass brand consequently represents both everyday consumer services and nationally significant communications infrastructure. Its position combines postal reach, telecommunications access, digital services and stewardship of Greenland's internet identity. The company continues to modernize its network mix while adapting service delivery to one of the world's most geographically challenging operating environments.
History
Tusass's institutional history reaches back to 1879, when postal and telecommunications activities began developing in Greenland. For much of the modern period, these functions were associated with separate organizations. TELE Greenland handled telecommunications, while Kalaallit Allakkeriviat operated Greenland's postal service. In 1997, TELE Greenland and Kalaallit Allakkeriviat were merged to create TELE Greenland A/S as a combined postal and telecommunications organization. The postal operation became a business unit called POST Greenland, and the shared public-facing designation TELE-POST came to describe the combined activities. The merger created an organization capable of coordinating postal delivery, telecommunications infrastructure and the logistical requirements of serving dispersed communities across Greenland. Mobile communications expanded in stages. GSM service began in 1998 in Nuuk, Ilulissat, Kangerlussuaq and Sisimiut. In 2009, TELE-POST partnered with Nokia Siemens Networks on a complete 3G network. A further Nokia Siemens Networks partnership supported the construction of a 4G network, which launched in Nuuk on 1 December 2013. Sisimiut followed in March 2014, and service later expanded to Ilulissat, Kangerlussuaq and Qaqortoq during 2014. Maniitsoq and Aasiaat received 4G in 2015. The company also developed a multi-layer connectivity system to cope with Greenland's geography. ADSL was introduced in 2004. Internet services were historically grouped into zones reflecting their underlying infrastructure: submarine cable, radio chain or satellite. Greenland Connect and Greenland Connect North provided high-capacity international and domestic cable connectivity, while an approximately 1,500-kilometre radio chain with dozens of stations extended telecommunications, internet, radio and television services beyond cable landing points. Satellite links served locations where neither cable nor terrestrial radio infrastructure was practical. In 2016, TELE-POST announced plans to upgrade the existing Greenland Connect system and build the Greenland Connect North extension. Products based on the upgrades launched in December 2017, including VDSL service with speeds of up to 30 Mbit/s in towns connected to the submarine-cable system. The company also pursued radio-chain upgrades intended to increase speeds and move communities from satellite-dependent service to terrestrial connectivity. In 2017, it announced a partnership with Ericsson to modernize the mobile network under a Mobile First strategy focused on expanding high-speed 4G access. Satellite infrastructure remained important. In 2017, service in several locations moved from Intelsat 903 to Intelsat 35e. Ground stations completed in Tasiilaq in 2020 and Ittoqqortoormiit in late 2021 enabled flat-rate broadband in those communities. In 2023, Tusass moved to the Hispasat Amazonas Nexus satellite, referred to by the company as GreenSAT, for flat-rate internet service to remote farms and Qaanaaq, where a new ground station was built. The company rebranded from TELE-POST to Tusass in 2021. The new name is Greenlandic slang meaning approximately “talk to you later,” giving the organization a shorter and more locally distinctive identity. The rebrand did not eliminate its core postal and telecommunications responsibilities. Tusass continued to operate the .gl domain, provide postal services, run commercial and IT activities, and manage essential national communications infrastructure. Tusass continued shifting toward mobile and wireless services. It closed fixed landline connections in 2022 and transferred customers to mobile products. That year it launched 5G Non-Standalone fixed wireless access in three cities, with speeds of up to 80 Mbit/s. In 2019, the company had selected Ericsson to build a 5G network. Tusass launched Voice over LTE in February 2025 and announced plans to retire older network generations, including the cessation of 3G service in 2026 and the continued availability of 2G until 2027. The company's stated technological direction is therefore toward modern mobile, fixed-wireless, cable and satellite systems adapted to Greenland's settlement pattern.
