Samsung Galaxy S9 pushes smartphone speed technology ahead on Australias fastest network

Telstra today announced the Samsung Galaxy S9, unveiled at Mobile World Congress, is the first smartphone to launch on Australia’s fastest mobile network featuring a high-speed Cat. 18 modem – theoretically capable of facilitating download speeds of up to 1.2Gbps.

Kevin Teoh, Head of Mobiles at Telstra said: “We are very excited by the potential of the Samsung Galaxy S9. As the first Cat. 18 handset launched with us, with the fastest theoretical download speeds to date, the Samsung Galaxy S Series may, once again, be the fastest phone on Australia’s fastest network.”

Kevin Teoh continues: “During testing on our live network, we have hit download speeds as high as 851Mbps. That’s fast enough to download an SD version of Rogue One: A Star Wars Story in just over 15 seconds. While customers are unlikely to see such speeds in the real world, Samsung Galaxy S9 and S9+ owners will be able to stream, surf and share at super speeds and we are excited by what this leading edge technology will allow us to offer customers in the future”.

Additionally, the Samsung Galaxy S9 and S9+ will both be configured for Telstra Messaging (which brings together advanced messaging features like visual voice mail, group chat and file sharing all into one inbox) and Wi-Fi Calling on the Telstra Network.

The Samsung Galaxy S9 and S9+ will be available to pre-order from Telstra from February 27 and on sale from March 16.
