Telstra

Telstra Corporation Limited, often referred to simply as Telstra, stands as Australia's largest telecommunications company and a significant player in the Oceania region. As a household name across the continent, Telstra provides a comprehensive range of services, including mobile, internet, and fixed-line solutions. Recognizable internationally by its Mobile Country Code (MCC) of 505 and Mobile Network Code (MNC) of 01, Telstra distinguishes itself within the Australian mobile landscape. Its extensive infrastructure allows it to offer broad coverage, particularly in rural and remote areas where rivals Vodafone and Optus may have a limited presence. Telstra’s commitment to innovation has also seen it lead the way in introducing new technologies, such as 5G, aimed towards enhancing connectivity for both consumers and businesses.  Serving millions of customers, Telstra’s history is intertwined with the very development of Australian telecommunications. Once a government-owned entity known as Telecom Australia, its privatisation in the late 1990s and early 2000s paved the way for a more competitive market. While competitors continue to challenge its dominance, Telstra’s deep roots, substantial investment in network infrastructure, and brand recognition maintain its position as a leading mobile network operator. Its focus on customer service and ongoing network upgrades contribute to its reputation within Australia and the broader Oceania region. The MCC 505, alongside the MNC 01, are vital components in identifying Telstra uniquely across global telecommunications networks, ensuring seamless roaming compatibility for its users traveling internationally.
