Overview
MobiFone is a Vietnamese telecommunications operator headquartered in Hanoi. The company began operations on 16 April 1993 as Vietnam Mobile Telecom Services Company and was established to launch and operate a Global System for Mobile Communications network in Vietnam. It developed into one of the country's principal mobile-service providers and remains one of the three large Vietnamese state-linked telecommunications operators alongside Viettel and VinaPhone. The company's original business was centered on mobile voice and messaging services. As Vietnam's communications market expanded, MobiFone built a broader service portfolio that included mobile data, digital connectivity, value-added services, and enterprise-oriented telecommunications offerings. Its organizational growth was supported by a network of mobile telecommunications service centers and a dedicated Value Added Services Centre. These units helped the operator expand beyond basic cellular access and manage services for different regions and customer segments. MobiFone's development included international technical and commercial cooperation. In 1995, it entered a business cooperation contract with Sweden's Kinnevik/Comvik. The arrangement formed part of the company's early effort to develop Vietnamese mobile telecommunications capability, although the cooperation was liquidated in 2005. That year also marked a change in the company's leadership and a government decision concerning the sale of equity, reflecting a broader period of institutional and ownership-related restructuring. The operator expanded its service-center structure during the 1990s and 2000s. Mobile Telecom Services Centres I and II were established in 1994, Centre III in 1995, Centre IV in 2006, and Centre V and the Value Added Services Centre in 2008. A further Mobile Telecom Services Centre VI was established in 2011. In 2008, MobiFone was reported as holding the leading position in Vietnam's mobile-telephony subscription market, an indication of the brand's importance during the rapid growth of mobile adoption in the country. A major institutional milestone came in 2015, when the enterprise became MobiFone Telecommunications Corporation under Vietnam's Ministry of Information and Communications. This change gave the business a corporate structure distinct from its earlier identity as a mobile telecom services company. MobiFone continued to operate primarily in Vietnam and remained focused on telecommunications rather than becoming a broadly international consumer brand. According to the cited 2023 market figures, MobiFone held 22.52% of Vietnam's telecommunications market, placing it second among the country's operators. Viettel was reported at 57.6%, VinaPhone at 17.49%, and Vietnamobile at 1.75%. Together, Viettel, VinaPhone, and MobiFone accounted for almost 98% of the market. These figures place MobiFone among the central participants in Vietnam's highly concentrated mobile-communications sector. Its positioning is therefore based on nationwide telecommunications infrastructure, established subscriber relationships, mobile connectivity, and the credibility associated with a major state-linked operator.
History
MobiFone traces its origins to 16 April 1993, when Vietnam Mobile Telecom Services Company was founded to develop mobile telecommunications in Vietnam. It began as a GSM operator, entering a market that was then at an early stage of development. The company's creation established a dedicated national mobile-services business at a time when fixed-line communications were still more prominent and cellular access was not yet widespread. The organization expanded its operating base during the 1990s. Mobile Telecom Services Centres I and II were established in 1994, followed by Centre III in 1995. That same year, the company entered a business cooperation contract with Sweden's Kinnevik/Comvik. The partnership was part of the technical and commercial development of MobiFone's early mobile network. The arrangement ended in 2005, when the business cooperation contract was liquidated. MobiFone's network and service organization continued to grow in the 2000s. Mobile Telecom Services Centre IV was established in 2006. In 2008, the company founded Centre V and a Value Added Services Centre. The expansion of the latter reflected the industry's movement beyond basic voice and text services toward supplementary mobile products and digital services. MobiFone was also reported to have reached the leading position in Vietnam's mobile-telephony subscription market in 2008, marking an important point in its development and market presence. The year 2005 brought several institutional changes. Alongside the end of the Kinnevik/Comvik cooperation, the Vietnamese state and the Ministry of Posts and Telematics, later renamed the Ministry of Information and Communications, decided to sell equity. Leadership also changed when Le Ngoc Minh became director following the retirement of Dinh Van Phuoc, the company's founding director. A further service-center expansion occurred in 2011 with the establishment of Mobile Telecom Services Centre VI. MobiFone's operating model consequently combined a national telecommunications brand with specialized and geographically organized service units. These structures supported the delivery and administration of mobile services as the Vietnamese market grew in scale and sophistication. In 2015, the enterprise became MobiFone Telecommunications Corporation under the Ministry of Information and Communications. The change formalized its corporate identity and marked a transition from the earlier company structure to a telecommunications corporation. MobiFone remained primarily a Vietnamese operator, with its business centered on domestic mobile connectivity and related services. By 2023, the company was described as Vietnam's second-largest telecommunications provider. Reported market shares were 22.52% for MobiFone, 57.6% for Viettel, 17.49% for VinaPhone, and 1.75% for Vietnamobile. The three largest state-linked providers together accounted for almost 98% of the market. MobiFone's history therefore reflects both the development of Vietnam's mobile sector and the continuing importance of large domestic operators in the country's communications infrastructure.
