Oh wow . I received a text message from Telstra
"Great news, we’ve added 5G access to all Pre-Paid plans & recharges at Telstra until 26 September 2022. This includes at no extra cost. Want to see how your 5G speed is performing? Turn your Wi-Fi off to test your mobile connection & speed performance tel.st/speedtest. Your data allowance will not be impacted by this test.

We are gradually adding 5G to all Pre-Paid recharges over the next few weeks. If you haven’t been notified that you’ve got 5G access yet, then it won’t be long! Please be patient and we will contact you once 5G is added to your service. 5G access may take up to 24 hours once added to your recharge. Please note, you must have an active recharge to remain eligible for the trial.
