Verizon ended RCS in Samsung Messages in January 2025 and directed its customers to Google Messages, and the other US networks have moved the same way. On a Samsung phone bought in the US today, Google Messages is normally the default texting app already, and RCS is on out of the box.
Which app carries Samsung RCS messaging
Google Messages. It is the RCS client for effectively every Android handset in the US, Samsung included, and it talks to the Jibe backend that Google runs for most carriers.
Samsung Messages still ships on some devices in some markets and still sends SMS and MMS perfectly well. What it no longer reliably does in the US is carry RCS. If your Galaxy is on Samsung Messages and chat features look missing or stuck, that is usually the whole explanation.
Turning RCS on
- Install or open Google Messages and set it as the default SMS app when prompted. On most US Galaxy phones it already is.
- Open the profile menu, then Messages settings, then RCS chats.
- Turn Turn on RCS chats on.
- Confirm your number and wait for the status to read Connected.
Step 4 is the one that takes time. Registration is a carrier-side handshake, and it can sit on "Setting up" for a few minutes on a new SIM. RCS waiting for activation covers what to do when it does not clear.
If RCS is not working on your Samsung
- Chat features missing entirely. You are almost certainly in Samsung Messages, not Google Messages. Change the default app.
- Stuck on connecting. Confirm the phone has data, not just Wi-Fi, for the first registration, and check the number shown matches the SIM.
- Working for some contacts only. RCS is per conversation. A thread with someone who has not enabled it stays on SMS, and that is normal, not a fault. See why RCS is not working.
- Dual SIM. RCS registers against one line. If you swapped the default data SIM, the registration follows it.
What Samsung support means if you send business messages
Nothing you need to build for. A verified RCS message reaches a Galaxy through Google Messages exactly as it reaches a Pixel, so there is no Samsung-specific payload, no separate approval, and no separate test device requirement beyond ordinary QA. Samsung is the largest Android handset base in the US, so in practice a large share of your Android-side RCS delivery lands on one.
The one operational note is fallback. A Galaxy on Samsung Messages with no RCS registration receives the SMS version of your send, which is the same behaviour as any other unregistered handset. How RCS falls back to SMS covers it.
- Samsung devices are RCS-capable; US carriers route Samsung RCS messaging through Google Messages.
- Verizon ended RCS in the Samsung Messages app in January 2025.
- Setting Google Messages as the default texting app is the fix for most "RCS missing on Samsung" reports.
- RCS registration is per line and per conversation, so partial coverage is expected behaviour.
- Business senders need nothing Samsung-specific: the same verified agent and the same payload reach a Galaxy through Google Messages.
