Google Messages RCS stuck on “Setting up” (or “Verifying”): a 2026 fix-it guide
The problem (and who it hits)
If Google Messages won’t enable RCS chats and sits forever on “Status: Setting up…” or “Trying to verify your phone number”, you’re not alone. It’s especially common right after:- switching to a new Android phone
- changing carriers (or porting your number)
- swapping SIM cards or converting to eSIM
- reinstalling Messages / resetting your phone
When RCS doesn’t register, you lose “modern texting” features (typing indicators, read receipts, better group chats, high-quality media) and can end up stuck on SMS/MMS.
Why it’s happening (what the sources suggest)
RCS is a carrier/phone-number–linked messaging service that requires successful phone number verification/registration inside Google Messages. When that registration flow breaks, Messages can’t complete setup and stays stuck.Google’s own troubleshooting guidance points to a few common culprits: data connectivity/SMS ability, Google Play services, and—importantly—corrupted or stale app state in Carrier Services and Google Messages, which Google explicitly recommends clearing in certain cases. [1]
Separately, Android Authority reported a recurring Google Messages/RCS activation bug affecting some users and noted two workarounds people report success with: (1) clearing app data for Carrier Services and Messages, and (2) temporarily reverting to an older Google Messages build to complete registration, then updating again. [2]
Finally, if you switched from iPhone to Android, Apple notes you may need to deregister iMessage so texts reliably route as SMS/MMS to your phone number. If your number is still associated with iMessage, some messages (especially from iPhone users) may not arrive as expected. [3]
Solutions (start here, then escalate)
Work through these in order. Stop when RCS connects.Solution 1: Confirm the basics (5 minutes)
1. Update Google Messages (Play Store) and ensure it’s your default SMS app. 2. Verify you can receive a regular SMS. 3. Turn Wi‑Fi off, use cellular data for 2–3 minutes, then try again (RCS setup needs a stable data path, and verification may involve SMS). 4. Restart your phone.Google specifically recommends checking your data connection, default SMS status, and versions before deeper resets. [1]
Solution 2: Toggle RCS off/on + “Retry/Verify”
1. Open Google Messages → your profile icon → Messages settings → RCS chats. 2. Toggle RCS chats off. 3. Force close Messages. 4. Reopen Messages and toggle RCS chats on. 5. Tap Retry or Verify your number if shown.If it flips between “Setting up” and “Verifying,” don’t panic—move to Solution 3.
Solution 3 (high success): Clear Carrier Services + Messages storage (Google’s official steps)
This resets the components that often hold stale registration state.Before you start: Google notes clearing storage won’t delete your SMS messages, but it will reset app settings and may temporarily affect RCS labeling/group behavior until RCS returns. [1]
1. Turn on Airplane mode.
2. Go to Settings → Apps → See all apps.
3. Find Carrier Services (may be “Show system” / “System apps”).
4. Tap Storage & cache → Clear storage (or “Clear data”), then Force stop.
5. Now find Messages (Google Messages).
6. Tap Storage & cache → Clear storage, then Force stop.
7. Turn Airplane mode off.
8. Wait a few minutes, then go back to Messages → Settings → RCS chats.
This is the single most “official” deep fix, since Google explicitly lists it when RCS won’t turn on. [1]
Solution 4: If you recently switched from iPhone, deregister iMessage (critical for missing texts)
If you moved your number off iPhone, do this even if your main issue seems like “RCS setup.”1. If you still have the iPhone: turn off iMessage and FaceTime in Settings.
2. If you don’t: use Apple’s online iMessage deregistration.
Apple explains that deregistering removes your number from iMessage so you can receive texts normally on a non‑Apple phone (it can take a bit for some devices to recognize the change). [3]
Solution 5: Deactivate RCS registration, then re-enable (useful after number changes)
If your number is “stuck” registered somewhere, deactivation can help force a clean re-register.1. In Google Messages: toggle RCS chats off.
2. Use Google’s Messages deactivation process/site (Google references a deactivation web flow in its ecosystem; many users use it as part of troubleshooting). [4]
3. Wait 5–10 minutes.
4. Toggle RCS chats on again and attempt verification.
Solution 6 (advanced / last resort): Roll back Messages briefly to complete verification
Android Authority reports some users only succeed by installing an older Google Messages version long enough to complete registration, then updating. This is a workaround for a recurring bug, not an official fix. [2]If you attempt this:
- Prefer safe sources and be cautious with APK sites.
- After RCS connects, update via the Play Store.
If you’re not comfortable with APK installs, skip this and go to Solution 7.
Solution 7: Carrier-side resets (when nothing else works)
At this point, your best bet is your carrier, because carriers can influence provisioning.Ask support for:
- confirming your line is provisioned for RCS
- checking for recent SIM swap / port blocks
- issuing a new SIM or converting to eSIM (some users report the SIM change itself resolves stuck registration)
Quick checklist (printable)
- [ ] Google Messages is default SMS app; app is updated. [1]
- [ ] You can receive a basic SMS; cellular data works. [1]
- [ ] RCS toggled off/on; phone restarted.
- [ ] Cleared Carrier Services storage + force stop. [1]
- [ ] Cleared Google Messages storage + force stop. [1]
- [ ] If switched from iPhone: deregistered iMessage. [3]
- [ ] RCS deactivated then re-enabled. [4]
- [ ] Escalated to carrier provisioning / SIM reissue.
FAQ
1) Will clearing Google Messages storage delete my texts?
Google says you won’t lose your messages, but you will lose Google Messages settings and may see temporary changes in how some chats are labeled until RCS returns. [1]2) Why does this happen right after I port my number?
Porting can leave your number in an “in-between” state across systems for a bit. RCS relies on phone-number registration and can fail if verification/provisioning doesn’t complete cleanly.3) I switched from iPhone and some friends’ texts don’t arrive—what now?
Deregister iMessage. Apple explicitly recommends this when you moved to a non‑Apple phone and aren’t getting SMS/MMS. [3]4) How long should “Setting up…” take?
Typically minutes, not days. If it persists for hours, treat it as a stuck registration and follow the reset steps (Carrier Services + Messages storage). [1]5) Is this a Google bug or my carrier?
It can be either. Google’s help page implies local app/device state and services versions matter, while reports show recurring activation bugs and workarounds. [1] [2]Key Takeaways
- RCS “Setting up” usually means registration/verification didn’t complete, often after device/SIM/carrier changes.
- The most effective official fix is often clearing Carrier Services and Google Messages storage (then retry). [1]
- If you came from iPhone, deregister iMessage to restore reliable SMS/MMS delivery. [3]
- If all else fails, your carrier may need to re-provision the line or issue a new SIM/eSIM.

Facts / actions:- Symptom: Google Messages RCS chats stuck on “Setting up” / “Verifying” after phone change, SIM/eSIM swap, carrier switch, or number port.
- Primary fix: Airplane mode on → clear storage for Carrier Services → force stop → clear storage for Google Messages → force stop → airplane mode off → retry RCS. [1]
- iPhone-to-Android: deregister iMessage (Settings or Apple online tool) to receive SMS/MMS normally. [3]
- Escalation: RCS deactivation + re-enable; carrier provisioning reset/SIM replacement.
