Telstra Messaging (RCS) platform change FAQ
From 23 May, we’re making changes to the way you can use Rich Communication Services (RCS) on your eligible Samsung device.
This change will make it easier to send RCS messages and will ensure a more consistent messaging experience when using Samsung Messaging.
Rich Communication Services (RCS) is a messaging service available on Android mobile phones, which provides customers a richer messaging experience. Unlike SMS, RCS enables a similar experience to WhatsApp and iMessage, where you can see when someone has read your message, or you can see when someone is typing a response.
Telstra’s solution for Rich Communication Services (RCS) will no longer be provided on Telstra’s network. Impacted customers will be given the option to continue using RCS via Google’s RCS solution.
If you are using one of the eligible Samsung devices listed in the table below and use Samsung Messages app on your device, you will be given the option to perform the update.
This change will allow you to use RCS messaging with more Android users and will ensure a more consistent messaging experience on Android devices.
Devices will be progressively updated, starting from 23rd May 2022. All devices are scheduled to be upgraded by 30 June 202.
It’s simple. Firstly, you will receive a software maintenance update message via your device. You apply that as per a normal software update, waiting for your device to restart.
Once the device has restarted you will click on to your Samsung Messages application and it will give you the option to turn on Google Chat features. If you consent to that and Google’s terms, the RCS service is enabled.
If you don’t consent, you can still use the Samsung Messages application on the device as you do today. However, your messaging experience will default back to SMS/MMS instead of RCS.
Any existing messages that you have in your messaging application will be maintained and will be available post the software upgrade.
If you are using the Group chat feature on the Samsung messaging application, make sure that you setup new group chats after you have made the software update.
Once you’ve created a new group chat you may find that some of your contacts cannot be added to the group. If this is the case, make sure that your contacts also have the latest Samsung messaging application installed on their device.
If you experience any issues relating to the software upgrade, you should contact Samsung.
