POST Telecom
Luxembourgish mobile telecommunications operator formerly branded as LuxGSM and subsequently integrated into POST Luxembourg.
Last updated August 24, 2026
Overview
Post Telecom is a Luxembourgish telecommunications operator whose mobile network was historically marketed under the LuxGSM name. It served the domestic Luxembourg market and became the country's largest mobile network by subscriber numbers, with approximately 250,000 customers reported in reference material. The business operated within the wider P&TLuxembourg group, a government-owned organization responsible for postal and telecommunications services. The LuxGSM name was used for the group's mobile offering before the business was consolidated under the POST Luxembourg identity. Between 2004 and 2009, LuxGSM also maintained a national partnership with Vodafone. During that period, LuxGSM customers could access Vodafone's network while roaming. The arrangement ended in early 2009, when Tango became Vodafone's partner network in Luxembourg instead. LuxGSM competed in the Luxembourg mobile market with Tango, Orange Luxembourg—formerly known as VOX mobile—and Join Experience. The competitive environment included traditional mobile voice and messaging services as well as broader telecommunications offerings. As the parent group unified its postal and telecommunications activities under a common commercial identity, P&TLuxembourg and LuxGSM were merged into a single POST Luxembourg brand on September 30, 2013. The former LUXGSM network was consequently renamed POST. Accordingly, LuxGSM is best understood as the former mobile-network brand and operating identity associated with the telecommunications activities now presented under POST Luxembourg and POST Telecom. The historical brand is no longer the principal customer-facing name, while the successor telecommunications operation remains associated with Luxembourg's domestic communications market.
History
Post Telecom traces its public identity to LuxGSM, the mobile telecommunications operation associated with P&TLuxembourg in Luxembourg. P&TLuxembourg was a government-owned corporation providing postal and telecommunications services, and LuxGSM operated as its mobile-network business. The operator served Luxembourg's domestic market and became one of the country's principal mobile providers. From 2004 through 2009, LuxGSM had a national partnership with Vodafone. The arrangement allowed LuxGSM customers to use Vodafone's network when roaming, extending the practical reach of the Luxembourg operator beyond its home market. The partnership ended in early 2009. Tango then became Vodafone's partner network in Luxembourg, marking a change in the international roaming and network-partnership landscape surrounding LuxGSM. Within Luxembourg, LuxGSM competed with several other mobile providers. The identified competitors included Tango, Orange Luxembourg—previously known as VOX mobile—and Join Experience. Reference material describes LuxGSM as having approximately 250,000 subscribers and as the largest network in Luxembourg by subscriber count at the time described. The decisive corporate and branding change occurred on September 30, 2013. P&TLuxembourg and LuxGSM were merged into one POST Luxembourg brand. As part of that consolidation, the LUXGSM network was renamed POST. This change ended LuxGSM's role as the principal commercial identity for the mobile service, while preserving the telecommunications operation within the broader POST organization. The Post Telecom subject therefore encompasses both the historical LuxGSM mobile brand and its transition into the POST Luxembourg telecommunications identity. The former name remains relevant for understanding Luxembourg's mobile-market history, Vodafone's former national partnership, and the development of the country's largest mobile network, but customer-facing activities are associated with POST rather than LuxGSM after the 2013 rebrand.
