T-Mobile may be one of the last to do it, but since tonight, the Android 9 Pie update is being introduced for the Samsung Galaxy S9 and [Galaxy99] ]. Not only that, they also activate RCS Universal Profile 1
Updates shipped as Build G960USQU3CSAB for the Galaxy S9 and G965USQU3CSAB for the Galaxy S9 +. Everyone weighs about 1.9 GB, so make sure you have enough storage and a long battery life before trying to use them.
The pie update for S9 and S9 + includes a major UI update from Samsung called One UI. It's a pretty big upgrade from the previous Samsung Experience software. So I recommend watching the following video to learn about the new features. Things will look different, Samsung has moved items, there is now a system-wide Dark mode, and the App Switcher is new. Again, it's pretty cool!
What is RCS Universal Profile 1.0? It's a messaging upgrade that allows you to send and receive larger media files, keep larger group chats, and know when someone is talking (more information here). It works between supported network operators, even if phones are supported, and it is assumed that this is the future of the text messaging system. Other T-Mobile phones to receive RCS support include the Galaxy S7, S7 Edge, all Galaxy S8 variants, Galaxy Note 8 and Galaxy Note 9.

As a reminder, Sprint, AT & T and Verizon have moved the Pie and One UI updates to their S9 units.
