Android RCS Messages Not Sending | Fix Delivery Fast

RCS gives Android texting chat-style features like typing indicators, read receipts, richer groups, and clearer media. When it fails, messages can hang on “Sending” with no clue why. The fix is usually a simple break in the chain: data, verification, or an app setting.

Before you change settings, look at the send indicator in Google Messages. In the compose bar, the icon can show whether the next message will go by Wi-Fi or mobile data, by SMS, or by MMS. If you see SMS or MMS when you expect RCS, the thread may not be eligible, or RCS may be disconnected. If you see a data send and delivery hangs, treat it like a network or verification stall. This clue saves time and keeps your next step focused. Source

What RCS Needs To Send Messages Reliably

RCS runs over Wi-Fi or mobile data, and it links your phone number to an RCS service. Before you chase deeper fixes, make sure these basics are true.

• Data can reach the internet — RCS needs a working Wi-Fi or mobile data connection.
• SMS can still arrive — Number checks may rely on standard SMS in the background.
• Your number shows Connected — In Google Messages, status should be Connected, not stuck verifying. Source
• Everyone in the chat has RCS on — Google notes that group and 1-on-1 RCS needs RCS enabled for all participants. Source
• Google Messages is default — Google’s troubleshooting includes checking that Google Messages is your default SMS app. Source

Android RCS Messages Not Sending On Wi-Fi Or Mobile Data

Start by checking status, then make a clean data test. You’re aiming to get RCS back to Connected and keep the app awake long enough to deliver.

Check The RCS Status In Google Messages

Open Google Messages, tap your profile icon, go to Messages settings, then open RCS chats (some phones show Chat features). Source

On the RCS chats screen, the status line is more than decoration. Connected means you can use RCS chats with people who have it on. Connecting means your number is still under verification. “Trouble connecting. Awaiting retry” means verification failed and the app will try again. If it sits there, wait a bit, then tap Retry when it appears. Not available can show up when data is off or the device or carrier can’t do RCS. If you see “disabled by your carrier,” the fix starts with carrier. If it stays in a bad state for over 30 minutes, open Details and send feedback from that screen. Source

• Confirm Connected — Connected means your number is verified and ready.
• Use Retry when shown — Retry can nudge a stalled registration.
• Read the carrier message — If it says your carrier disabled RCS, the carrier must clear it. Source

Do A Fast Connection Reset

RCS can look “online” while the network is half-broken. Prove the pipe with a couple of quick moves.

• Toggle Airplane mode — Turn it on for 10 seconds, then off.
• Switch networks — Try one send on Wi-Fi, then one on mobile data.
• Load a web page — Confirm your browser can open a site.

Set Google Messages As Default And Restart It

When two messaging apps fight over SMS or notifications, RCS can misbehave. Google’s guidance includes checking the default messaging app. Source

• Pick Google Messages — In Android Settings, set Google Messages as the SMS app.
• Force stop Messages — Open App info, tap Force stop, then reopen.
• Send one plain text — Try a short message to confirm delivery.

Fix Setup And Verification When RCS Won’t Connect

When status sits on Connecting or Awaiting retry, the phone is trying to verify your number. Most “not sending” reports clear once verification completes.

Confirm Your Line Can Receive SMS

Verification can depend on standard SMS in the background. If SMS can’t arrive, RCS can loop.

• Receive a test SMS — Ask someone to text you a plain message.
• Check dual SIM defaults — Set the correct SIM as the default for SMS.
• Restart the phone — Reboots often clear stuck verification states.

If you use Google Fi, check that message sync isn’t enabled. Google says Fi message sync turns RCS off, so RCS chats won’t connect until you stop sync on the current phone and sign out of web sync. In Google Messages, open Messages settings, then Advanced, then Google Fi Wireless settings, and stop sync and sign out. After that, return to RCS chats and tap Retry, then test again. Source

Reset RCS Registration In One Sitting

Google’s troubleshooting page suggests turning RCS off, then back on in Messages settings when RCS won’t sync or messages aren’t coming through. Source

Google also notes it’s not advised to flip RCS on and off unless you’re fixing missing messages or swapping devices, since it can affect group chats. Source

• Turn RCS chats off — Settings > RCS chats, switch it off.
• Wait 60 seconds — Keep Messages open while you wait.
• Turn RCS chats on — Switch it back on and watch for Connected.

Use Google’s Deactivation Page After A Device Switch

If you moved to a new phone and don’t have the old one, Google offers a deactivation page to remotely turn RCS off for your number. Then you can enable it again on your current device. Source

• Request the 6-digit code — Enter your number and get the SMS code.
• Deactivate RCS — Submit the code to disable RCS for that number.
• Re-enable on phone — Turn RCS chats on again in Google Messages.

Fix App Bugs And Background Blocks

Once status shows Connected, the next most common cause is the app getting paused, out of date, or blocked from using data in the background.

Update Messages, Play Services, And Android

Google’s Help Center calls out updating Google Messages, keeping Google Play services current, and running Android 5.0 or higher. Source

• Update Google Messages — Install any Play Store update, then reopen the app.
• Update Google Play services — Update it, then reboot to refresh background services.
• Check Android version — If your phone is below Android 5.0, RCS won’t work.

Clear Cache And Remove Sleep Rules

Quick check: If sends work only when Messages is open, the phone may be freezing it. Clear cache and remove battery limits so the connection stays alive.

• Clear Messages cache — App info > Storage > Clear cache, then relaunch.
• Turn off Battery Saver — Disable it, then test a send with the screen off.
• Allow background data — In App info, allow background data when available.
• Remove sleeping rules — On Samsung, check Sleeping apps and remove Messages.

Check Data Saver, VPN, And Private DNS

If sending fails on one network type, test without filters. Some VPNs, Private DNS setups, and Data Saver modes can block the path RCS uses.

• Turn off Data Saver — Retry a send, then turn it back on if needed.
• Pause VPN apps — Test sending, then re-enable your VPN.
• Set Private DNS to Automatic — Retry after the change.

Fix Chats That Fail With One Contact Or One Group

When RCS works with some people but not others, the thread often needs a reset or you’re texting a number that isn’t on RCS.

Start A New Thread And Confirm The Send Method

Google Messages shows whether a message will send by Wi-Fi/data, SMS, or MMS. That indicator helps you catch a thread that’s stuck in the wrong mode. Source

• Start a new chat — Send a short test message to the same person.
• Check group readiness — In groups, everyone needs RCS enabled for RCS features. Source
• Resend as SMS/MMS — Long-press the stuck message and resend as SMS or MMS.

Set Resend Preferences So You Don’t Stall

In RCS settings, you can choose how Messages resends when a data send fails. Google notes that “SMS with a link” can make media accessible by a public link outside Google’s control. Source

• Choose a fallback — Pick SMS or MMS if you need reliable delivery.
• Use link fallback carefully — It can help large files send, but it changes access.
• Retry after a network swap — Switch Wi-Fi/data, then resend from the thread.

Fix Number Mix-Ups In Contacts

If a contact has multiple numbers saved, you might be messaging a line that can’t use RCS. Clean up the contact and restart the chat.

• Review saved numbers — Keep the number that actually replies.
• Create a fresh group — Rebuild the group after confirming each number.
• Ask the contact to enable RCS — On their phone, turn RCS chats on in Messages settings.

When Nothing Works: Reset Cleanly And Report The Right Details

If the same stall keeps coming back, do a tidy reset and gather details that help a carrier or Google pinpoint the cause.

Reset Network Settings As A Last Step

This wipes saved Wi-Fi networks and Bluetooth pairings. It can clear stale network configs that block RCS on some devices.

• Open Reset options — Settings > System > Reset options.
• Reset Wi-Fi and mobile — Tap Reset Wi-Fi, mobile & Bluetooth.
• Test one RCS send — Reconnect, then try again.

Send Feedback From The RCS Status Screen

Google suggests using the Details link and then Submit feedback when you can’t connect after a carrier clears a block. Source

• Open RCS chats — In Messages settings, open RCS chats.
• Tap Details — Open Details on the status page.
• Submit feedback — Send the report while the stall is happening.

Call Your Carrier With A Clear Ask

If your status says your carrier disabled RCS, the carrier needs to remove that block so Messages can connect. Source

• Share the status text — Tell them the exact wording shown in RCS chats.
• Give a time window — Note when sending started failing and if it fails on Wi-Fi and data.
• Request provisioning checks — Ask them to confirm RCS and SMS delivery are enabled on your line.

If android rcs messages not sending still happens after these steps, stick to a simple test: one short text to one contact on Wi-Fi, then on mobile data. Save the results, then share them with your carrier and through Submit feedback so the logs match what you saw on screen.
