A statement from Optus said the devices used had Qualcomm Snapdragon X50 5G modems and the call was made on 3GPP-compliant networks. 3GPP is the industry body that works with the International Telecommunications Union to set standards for 5G.
Engineers from Singtel and Optus made instant on-screen annotations to exchange view on the live 5G sites, the statement said, adding that consumers could use this kind of call for immersive gaming, virtual tactile shopping and holographic calls.
Optus chief executive Allen Lew said: "“Once again Optus has proven our 5G agility, working collaboratively with our colleagues in Singapore to successfully land a ground-breaking 5G inter-country AR video call.

Mark Chong, group chief technology officer, Singtel, said: “This call is a significant marker in our journey to 5G as we develop a robust 5G ecosystem to ensure that our enterprise and consumer customers will enjoy an enhanced connectivity experience. 5G is a key enabler that will bring the future of AR, autonomous vehicles and smart cities closer to reality.”
Martin Wiktorin, country head, Singapore, Brunei and the Philippines, Ericsson, added: "The success of this video call using 5G test devices and AR in a multi-party environment, brings us a step closer to having our mobile broadband experience transformed with a mere click.
"With the establishment of 5G connectivity on smartphones soon becoming a reality, consumers and enterprises will be able to unleash the full potential of 5G by integrating this new technology into their daily lives and operations.”
And Peter Huang, president of OPPO APAC, said: “Once again, OPPO has pushed the boundaries of what is possible in a smartphone. The call is another 5G first for OPPO, and demonstrates our commitment to become one of, if not the first manufacturer to commercialise a 5G smartphone.
"We've been preparing for 5G technology for a number of years and have committed 10 billion yuan (A$2.1 billion) this year alone in R&D investment as we usher in our 5G future. We’re excited about what the next evolution of the mobile network will bring.”
Optus is building 50 new network sites and conducting critical inter-operability device testing along with Ericsson to deliver a compatible 5G home broadband product.
