You open Google Messages, head to Messages settings > RCS chats, and find the status stubbornly parked at “Setting up.” Ten minutes pass. Then an hour. At this point, the feature appears to be setting up a small government rather than verifying a phone number.
This problem usually means Google Messages cannot complete the phone-number verification required to activate Rich Communication Services, better known as RCS. Depending on your app version, the setting may still be labeled Chat features. Once connected, RCS enables internet-based messaging, typing indicators, read receipts, better group conversations, and higher-quality media sharing.
The good news is that “Setting up” rarely means your phone is permanently incompatible. It is more commonly caused by an outdated app, an incorrect SIM configuration, blocked verification texts, a stale registration from an old phone, or corrupted temporary app data. Work through the following fixes in order, testing the RCS status after each one.
What Does “Setting Up” Mean in Google Messages?
Google Messages must verify that the mobile number attached to your SIM belongs to the device requesting RCS access. During this process, the RCS status may appear as Connecting, Setting up, or Trying to verify your number.
Google describes “Connecting” as the stage when your number is still being verified. A “Trouble connecting. Awaiting retry” message indicates that verification has encountered a problem. If that warning remains for more than 30 minutes, Google recommends opening its details and submitting feedback.
A brief setup period is normal. A status that remains unchanged for hours or days is not. You should begin troubleshooting when:
- The status has not changed after approximately 30 minutes.
- You repeatedly see “Trying to verify” or “Awaiting retry.”
- The problem began after changing phones, SIM cards, carriers, or phone numbers.
- RCS previously worked but suddenly disconnected.
- You cannot receive the verification SMS.
Quick Checks Before Using Advanced Fixes
Start with the gloriously unexciting basics. They solve more technology problems than anyone wants to admit.
Confirm That Google Messages Is Your Default SMS App
Google Messages must normally be the default SMS application before it can activate and manage RCS correctly.
- Open your phone’s Settings.
- Tap Apps or Default apps.
- Select SMS app.
- Choose Messages by Google.
Open Google Messages again and return to Profile picture > Messages settings > RCS chats. Google lists using Messages as the default SMS app among its primary RCS troubleshooting requirements.
Make Sure SMS and Mobile Data Work
RCS uses Wi-Fi or mobile data for conversations, but activation may still involve an SMS-based phone-number check. Therefore, you need a functioning internet connection and the ability to receive ordinary text messages.
Turn off Wi-Fi temporarily and verify that mobile data works by loading a website. Then send a regular SMS to another number and ask someone to text you back. If standard SMS is blocked, suspended, or unavailable, RCS verification may never finish. Google specifically advises confirming that the phone can receive SMS, while carrier troubleshooting guides emphasize having a working mobile-data connection and adequate cellular coverage.
Restart the Phone
A restart refreshes the SIM connection, mobile network registration, background Google services, and the Messages app. Turn the phone completely off, wait about 30 seconds, and power it back on. Do not merely lock the screen and stare at it sternly. Phones remain largely immune to intimidation.
How to Fix RCS Chat Features Stuck at Setting Up
1. Update Google Messages
An outdated version of Google Messages may contain activation bugs or may be incompatible with current carrier provisioning.
- Open the Google Play Store.
- Search for Google Messages.
- Tap Update if the button is available.
- Restart your phone after the update.
Google recommends keeping Messages updated when diagnosing RCS activation problems. App updates also deliver stability fixes and current feature support.
2. Update Carrier Services and Google Play Services
On some Android phones, the Carrier Services app helps the device communicate with carrier messaging systems. Search for Carrier Services in the Play Store and update it if it is installed. Some devices do not use a separately visible Carrier Services app, so do not panic if you cannot find it.
You should also update Google Play Services and install pending Android system updates. Google’s RCS troubleshooting guidance recommends checking the versions of Messages, Android, and Google Play Services.
3. Use the Verify Your Number Option
Open Google Messages and follow this path:
Profile picture > Messages settings > RCS chats
If you see Verify your number, Retry, or Details, tap it. Confirm that the displayed number is correct, including the proper country code. Google will attempt to send an SMS to verify the line.
If the number is wrong, check:
- Whether the active SIM is assigned the correct phone number.
- Whether you recently ported the number to another carrier.
- Whether your prepaid plan has sufficient balance to send or receive SMS.
- Whether your carrier account blocks verification codes, short codes, or commercial messages.
Carrier-level message blocking can prevent one-time PINs and security codes from reaching the device, so contact your carrier if other verification texts are also missing.
4. Toggle RCS Chats Off and Back On
A simple re-registration often clears a temporary provisioning failure.
- Open Google Messages.
- Tap your profile picture.
- Select Messages settings.
- Tap RCS chats or Chat features.
- Turn RCS off.
- Restart the phone.
- Return to the same menu and turn RCS on again.
Google and Verizon both recommend toggling RCS off and on when the service fails to connect. While RCS is disabled, messages may be sent as SMS or MMS, without typing indicators, read receipts, or other enhanced features.
5. Check Dual-SIM Settings
Dual-SIM phones are frequent offenders. RCS may attempt to verify one SIM while mobile data is assigned to the other, creating the digital equivalent of mailing your house key to your neighbor.
- Open Settings.
- Tap Network & Internet, Connections, or SIM manager.
- Identify the SIM containing the number you want to use with RCS.
- Set that SIM as the default for calls, SMS, and mobile data.
- Temporarily disable the second SIM if verification still fails.
- Restart Google Messages and try again.
Google’s RCS FAQ specifically advises dual-SIM users to make sure the calling SIM is also configured as the data SIM.
6. Clear the Google Messages Cache
A damaged cache can trap the application in an outdated setup state.
- Open Android Settings.
- Tap Apps.
- Select Messages.
- Tap Storage & cache.
- Select Clear cache.
- Tap Force stop, reopen Messages, and check the status.
Clearing the cache removes temporary files rather than permanently deleting the app’s stored data. Menu names may vary slightly between Pixel, Samsung, Motorola, OnePlus, and other Android phones.
7. Reset Messages and Carrier Services Data
If clearing only the cache does not work, resetting app storage can force RCS to begin a fresh provisioning session. This is a more aggressive step, so back up important information and review your device manufacturer’s instructions first.
- Turn on Airplane mode.
- Open Settings > Apps > Messages.
- Tap Storage & cache.
- Select Clear storage or Clear data.
- If Carrier Services is installed, repeat the process for that app.
- Restart the phone.
- Turn off Airplane mode.
- Open Messages, restore your preferences, and enable RCS again.
A Google Messages community guide recommends clearing Messages storage when the Retry option does not resolve stuck verification. However, Android’s general documentation warns that clearing storage permanently removes an app’s stored data. Your SMS database may be managed separately on many devices, but behavior can differ, so creating a backup before this step is the safer approach.
8. Deregister RCS From Your Old Phone
This step is especially important when the problem began after moving your SIM to a new device. Your number may still be registered for RCS on the old phone.
If you still have the previous phone:
- Connect it to the internet.
- Open Google Messages.
- Go to Messages settings > RCS chats.
- Turn RCS chats off.
- Wait briefly, then try activation on the new phone.
If the old device is lost, broken, traded in, or already factory-reset, use Google’s official RCS deactivation portal. Enter your number, receive the six-digit verification code, and remotely deactivate the previous registration. Google notes that leaving RCS disabled for 30 days may remove the number from RCS group conversations.
9. Temporarily Disable VPNs, Private DNS, and Data Restrictions
A VPN, firewall, aggressive ad blocker, restricted background-data setting, or custom Private DNS configuration may interfere with the connection between Google Messages and the RCS provisioning service.
Temporarily disable these tools, allow unrestricted background data for Google Messages and Carrier Services, and try activation over normal mobile data. You can restore your preferred privacy settings after the status changes to Connected.
10. Reset Mobile Network Settings
If the phone still cannot register properly, reset its mobile network configuration. The location varies, but it is commonly found under:
Settings > System > Reset options > Reset mobile network settings
On Samsung phones, look under:
Settings > General management > Reset > Reset mobile network settings
This can remove saved mobile-network preferences and may reset Wi-Fi or Bluetooth information on some devices. Read the confirmation screen carefully before proceeding.
11. Contact Your Carrier
If Google Messages says that RCS is disabled by your carrier, Google recommends contacting the carrier directly. Ask the support representative to confirm:
- RCS is supported for your device and account.
- Your line is correctly provisioned after a SIM or eSIM change.
- SMS, short codes, and verification messages are not blocked.
- Your number port has fully completed.
- Your account has the correct device identifier and messaging features.
Carrier implementations can differ. For example, Verizon directs customers toward Google Messages for supported RCS service and no longer supports RCS through Samsung Messages on certain configurations.
Fixes for Common RCS Activation Scenarios
RCS Stopped Working After Switching Phones
Turn off RCS on the old phone or use Google’s remote deactivation page. Confirm that Google Messages is the default app on the new device, update it, restart the phone, and verify the number again.
RCS Is Stuck After Installing an eSIM
Confirm that the eSIM is active for mobile data and SMS. Disable any old physical SIM temporarily, restart the phone, and retry verification. If the eSIM was activated recently, the carrier may need to complete account provisioning.
The Verify Button Does Nothing
Turn off Wi-Fi, confirm that mobile data works, clear the Messages cache, and restart the device. Also test whether you can receive ordinary SMS verification codes from other services.
RCS Works on One SIM but Not the Other
Make the affected SIM the default for data, calls, and texts. Temporarily turn off the other SIM during activation. Once RCS displays Connected, you can test whether re-enabling the second SIM affects the connection.
The Status Says “Not Supported”
Check your internet connection, app version, device compatibility, carrier support, and regional availability. If the message explicitly states that your carrier disabled RCS, the solution must come from the carrier rather than another round of cache-clearing aerobics.
What Not to Do While RCS Is Setting Up
Avoid repeatedly toggling RCS every few seconds. Each attempt may restart the verification process. Make one change, restart when appropriate, and give the service time to respond.
Do not repeatedly request verification codes. Too many attempts can trigger temporary limits. You should also avoid factory-resetting the entire phone before trying the less destructive fixes above. A factory reset is an enormous hammer for a problem that is usually a loose screw.
Finally, do not clear app storage casually. Start with cache clearing, read the warning displayed by your phone, and back up important data before deleting storage.
How to Know When Google Chat Features Are Fixed
Return to Google Messages > Messages settings > RCS chats. The status should display Connected. You can then open a conversation with another RCS user and check for several signs:
- The message field says RCS message instead of Text message.
- Typing indicators appear when enabled.
- Sent, delivered, and read icons appear.
- Photos and videos can be shared at better quality.
- The conversation automatically uses Wi-Fi or mobile data.
Both participants must have compatible RCS service enabled for all enhanced features to appear. Otherwise, Google Messages may fall back to SMS or MMS.
Experience Notes: What Usually Fixes a Stuck RCS Setup
The following is a composite troubleshooting experience based on recurring activation patterns rather than a claim about one specific phone or customer.
A typical case begins after someone upgrades to a new Android phone. The SIM is moved, Google Messages imports the existing conversations, and everything appears normal until the user opens RCS settings. The status says “Setting up,” so the natural response is to wait. Waiting is reasonable at first. After several hours, however, it becomes clear that the phone is not simply thinking deeply about its life choices.
The first attempt is often a restart. It may not solve the problem, but it removes temporary network glitches and establishes a clean starting point. The next useful step is checking whether Google Messages is actually the default SMS app. On phones that include both Samsung Messages and Google Messages, the wrong default can quietly derail activation.
Next comes the simplest revealing test: turn off Wi-Fi and send an ordinary text message. In many cases, this exposes the real issue. The user may have working Wi-Fi but no active mobile data, an incomplete eSIM activation, or a carrier account that cannot receive verification texts. RCS looks like the broken feature, but it is merely the first app brave enough to complain.
When calls, SMS, and mobile data all work, updating Messages and Carrier Services is usually the next productive move. Outdated components are especially common on a newly restored phone because the device may have downloaded user data before finishing all Play Store updates.
Dual-SIM phones add another twist. A common pattern is that the desired number is selected for calls and texts while the second SIM supplies mobile data. Matching the call, text, and data defaults to the same SIMor temporarily disabling the other SIMoften allows verification to complete within minutes.
If the number was recently transferred from an old phone, deregistration becomes the strongest suspect. Turning RCS off on the old device or using Google’s remote deactivation tool can release the number from the previous registration. This step is frequently more effective than repeatedly clearing the new phone because the actual conflict exists elsewhere.
Cache clearing comes later, not first. It is quick and relatively low risk, but it cannot repair a carrier account that is improperly provisioned. Clearing storage is more disruptive and makes sense only after checking the default app, updates, SMS reception, SIM settings, and old-device registration.
The most useful troubleshooting habit is changing one variable at a time. If you update three apps, reset the network, clear two storage areas, swap SIM defaults, and perform a ceremonial reboot all at once, you may fix the issuebut you will never know why. A measured process also reduces the chance of accidentally creating a second problem while solving the first.
In practice, the winning combinations are usually simple: update the apps and restart; align dual-SIM settings; permit verification SMS; or deactivate RCS on the previous phone. When none of those works, carrier support should check the line rather than telling the customer to reboot for the ninth time. Reboots are helpful, but they are not a personality.
Conclusion
When Google Chat Features or RCS chats remain stuck at “Setting up,” the phone is usually failing to verify or provision your mobile number. Begin with Google Messages updates, a working SMS and mobile-data test, the correct default messaging app, and a restart. Then check dual-SIM assignments, toggle RCS, clear the app cache, and deregister the number from any previous device.
Reserve storage resets and mobile-network resets for later in the process. If the app reports that RCS is disabled by your carrieror if the problem began during a number port, SIM replacement, or eSIM activationcontact the carrier and request a line-provisioning review.
Note: Android menu names and RCS availability vary by device, software version, country, and carrier. Back up important data before clearing app storage or resetting network settings.
