More about Optus
Optus won Australia's second general carrier licence in January 1991 and launched its GSM mobile service in May 1993. Singtel took it over in a deal completed on October 23, 2001. Its head office is in Macquarie Park, Sydney, and it had more than 10.7 million mobile customers in 2025.
Optus began rolling out 4G in 2012, switched off 2G on August 1, 2017, and shut down 3G on October 28, 2024. A data breach that began around September 22, 2022, and a nationwide outage on November 8, 2023, which hit more than 10 million customers, were its two worst years in the news. Its phones use the APN yesinternet, with a separate APN, mms, for picture messages.
