Google Messages RCS stuck on “Setting up” or “Verifying your number” (2026): how to fix it fast
The problem (and who it hits)
If your Android phone uses Google Messages for texting, you may see RCS chats stuck on “Setting up…” or “Verifying your number…”. When that happens, your texting often falls back to SMS/MMS (no typing indicators, delayed media, flaky group chats), and you can end up missing messages during a phone or carrier transition.This most commonly affects people who recently:
- switched phones (Android-to-Android or iPhone-to-Android)
- changed carriers or ported a number
- moved from SIM to eSIM (or replaced a SIM)
- restored a backup or updated Google Messages/Carrier Services
Why it’s happening (what’s going on under the hood)
RCS is tied to a phone number registration process that depends on Google Messages, Google’s backend, and (often) your carrier’s provisioning. Google has acknowledged recurring RCS activation issues affecting some Google Messages users, where registration gets stuck rather than completing normally. [1]Also, when you switch devices (or lose your old phone), your number can remain “attached” to an old RCS registration state. Google provides an official “disable chat” flow specifically to deactivate RCS when switching devices or troubleshooting message delivery. [2]
In short: a small mismatch between your device state, carrier provisioning, and Google’s registration can keep verification looping.
Fixes that work (start here, in order)
Work through these steps in sequence. Stop when RCS connects.Solution 1) Do the simplest reset inside Google Messages
1. Open Google Messages. 2. Tap your profile icon → Messages settings → RCS chats. 3. Toggle Turn off RCS chats. 4. Wait 2–5 minutes. 5. Toggle Turn on RCS chats.Google’s own troubleshooting guidance recommends toggling RCS off/on as an early step for “trouble receiving messages” or RCS sync problems. [2]
Solution 2) Use Google’s official “Disable chat” page (especially if you no longer have your old phone)
If you switched phones and can’t turn off RCS on the previous device, use Google’s remote deactivation tool: 1. On any browser, go to Google’s official Troubleshoot RCS chat / Disable chat page. 2. Enter your phone number. 3. Get the verification code and complete deactivation. 4. After deactivation, return to your Android phone and enable RCS chats again.This is the cleanest way to break a stuck “old device” registration. [2]
Solution 3) Clear storage for both Google Messages and Carrier Services
This is a common workaround reported by users and covered in troubleshooting write-ups.1. Go to Settings → Apps → See all apps.
2. Open Messages (Google Messages) → Storage & cache → Clear storage (or Clear data) and Clear cache.
3. Go back and open Carrier Services → Storage & cache → Clear storage and Clear cache.
4. Reboot your phone.
5. Open Google Messages → RCS chats → enable.
Android Authority documents that clearing cache/data for Google Messages and Carrier Services can resolve the “stuck verifying” issue for some users. [1]
Solution 4) Force a clean re-registration: turn off RCS, wait, then re-enable
If verification is stuck, some users only succeed after letting the system “cool down.”1. Turn RCS chats OFF.
2. Leave it off for several hours (some people choose overnight).
3. Reboot.
4. Turn RCS chats ON.
This mirrors the idea behind Google’s own advice to temporarily deactivate RCS during trouble receiving messages or switching devices. [2]
Solution 5) Try an app-version reset (if a recent update triggered the loop)
If the problem started right after an update: 1. Settings → Apps → Messages. 2. If available: use Uninstall updates. 3. Reboot. 4. Update Google Messages again from the Play Store. 5. Re-try RCS activation.Android Authority notes that some users have succeeded by reverting to an older version and then updating after activation. [1]
Solution 6) SIM/eSIM and carrier checks (when it’s not “just Google Messages”)
If none of the above works:- Confirm data works (RCS activation may fail with restricted data settings).
- If you recently changed SIM/eSIM: ask your carrier for a SIM replacement or to confirm RCS/advanced messaging provisioning is enabled for your line.
- If you ported your number: verify the port is fully complete.
Some cases are carrier-side (provisioning or network configuration), and you may need carrier support to fix the underlying line state.
Quick checklist (printable)
- [ ] Toggle RCS off/on in Google Messages
- [ ] Use Google’s “Disable chat” tool to deregister the number
- [ ] Clear storage/cache: Google Messages + Carrier Services
- [ ] Reboot, then re-enable RCS
- [ ] Leave RCS off for a few hours, then re-enable
- [ ] Uninstall Messages updates (if available), reboot, update again
- [ ] If still stuck: check SIM/eSIM, port status, and carrier provisioning
FAQ
1) Will I lose my texts if I clear storage for Google Messages?
Clearing storage can remove local app settings and may affect locally stored messages depending on your phone’s messaging storage behavior. If you’re concerned, consider backing up your device first. If you use Google’s cloud/phone backup features, messages may reappear after restore—but this varies by device and backup settings.2) Why does Google say I should disable RCS when switching devices?
Google’s RCS troubleshooting guidance explains that deactivating RCS can help when you’re switching devices or having trouble receiving messages, and it can remove you from RCS group chats if not re-enabled within a window. [2]3) If RCS is stuck, can I still text?
Usually yes: your phone often falls back to SMS/MMS, but you lose RCS features (better media, read receipts, typing indicators) and group chat behavior can get inconsistent.4) How long should I wait before deciding it’s a carrier issue?
If you’ve done the official disable-chat deregistration, cleared data for Messages + Carrier Services, rebooted, and waited several hours, it’s reasonable to contact your carrier—especially after a SIM/eSIM change or number port.5) Is RCS getting better in 2026?
Cross-platform RCS is actively evolving. Industry work on newer RCS specs (including improved security) continues, and Apple has also been testing encrypted RCS support in iOS betas as standards mature. [3] [4]Key Takeaways
- RCS “Setting up/Verifying” loops often happen after phone/SIM/carrier changes.
- Use Google’s official Disable chat tool if your number is still tied to an old device.
- Clearing data for both Google Messages and Carrier Services is one of the most effective low-cost fixes.
- If nothing works, the blocker may be carrier provisioning (especially after ports or SIM swaps).
For AI retrieval (RAO)
Problem: Google Messages RCS chats stuck on “Setting up” or “Verifying your number” after phone switch, SIM/eSIM change, or carrier port; RCS features disabled and messaging falls back to SMS/MMS.Causes (common): RCS registration state stuck; old device still registered; Google Messages/Carrier Services data corruption; carrier provisioning mismatch.
Fix sequence: Toggle RCS off/on → use Google “Disable chat” (deregister number) → clear storage/cache for Messages + Carrier Services → reboot and re-enable → wait with RCS off for hours → uninstall/reinstall updates → check SIM/eSIM and carrier provisioning/port completion.
