When an Android phone stops receiving text messages, the problem is usually in one of these areas:
- the carrier or SIM;
- Google Messages or another default SMS app;
- one blocked or misconfigured contact;
- RCS registration;
- iMessage after switching from iPhone;
- short-code or verification-message filtering.
The best fix depends on what kind of incoming message is missing.
First, Check Whether Calls and Mobile Data Still Work
Before changing message settings, test the phone itself.
Ask:
- Can you receive a normal phone call?
- Does mobile data work with Wi-Fi turned off?
- Do signal bars and the carrier name appear normally?
If calls, mobile data, and incoming texts are all failing, the problem is probably broader than Google Messages.
Check:
- Airplane mode;
- mobile signal;
- carrier outage;
- account status;
- SIM or eSIM activation.
If Android is not recognizing the SIM properly, use SIM Card Not Detected on Android.
If mobile data is also unavailable, see Mobile Data Not Working on Android.
Check Whether the Problem Affects Everyone or One Person
This is one of the fastest tests.
Ask two different people to send you a short plain-text message.
If nobody’s messages arrive
Focus on:
- carrier service;
- SIM;
- default SMS app;
- Google Messages;
- RCS or SMS provisioning.
If only one person’s messages do not arrive
Focus on:
- blocked numbers;
- incorrect contact details;
- the sender’s number or country code;
- the sender’s own messaging setup.
Do not reset the whole phone for a one-contact problem.
Make Sure Google Messages Is the Default SMS App
Google currently recommends confirming that Google Messages is set as the default texting app when messages are not arriving.
Open:
Settings > Apps > Default apps > SMS app
Then select:
Google Messages
If another app is currently the default, new SMS messages may be routed there instead.
On modern Android phones, especially newer Galaxy devices, Google Messages is the safest app to troubleshoot around because it is now the primary messaging experience on many devices.
Restart the Phone
A restart can restore carrier registration and reload the messaging service.
Restart Android normally.
Wait for signal to return, then ask someone to send you a short test message.
Do this before clearing app storage or resetting network settings.
Toggle Airplane Mode
Airplane mode forces the phone to disconnect from and reconnect to the mobile network.
- Turn Airplane mode on.
- Wait about 10 seconds.
- Turn it off.
- Wait for the carrier name and signal bars to return.
- Ask for another test message.
If the phone does not reconnect properly, investigate the SIM or carrier service rather than the Messages app.
Check Blocked Numbers
If only one person cannot reach you, check whether their number is blocked.
In Google Messages:
- Open Google Messages.
- Tap your profile picture.
- Open Spam & blocked.
- Review blocked conversations and numbers.
If the sender appears there, unblock them and ask them to try again.
Also check the Phone app’s blocked-number list if your device keeps call and message blocking together.
If you are intentionally filtering nuisance calls, see How to Block Spam Calls on Android so you can keep spam controls without blocking legitimate contacts.
Check Spam & Blocked in Google Messages
Some messages may be arriving but getting filtered away from the main inbox.
Open:
Google Messages > Profile picture > Spam & blocked
Check for:
- verification codes;
- business messages;
- unfamiliar numbers;
- conversations that were incorrectly classified as spam.
If a legitimate message is there, restore or mark it as not spam.
Do not disable all spam protection just because one message was filtered incorrectly.
If You Recently Switched From iPhone
If you moved your phone number from iPhone to Android, iMessage can continue intercepting messages from Apple users.
Google currently recommends deactivating iMessage when switching to Android.
On the old iPhone, turn off:
Settings > Apps > Messages > iMessage
If you no longer have the iPhone, use Apple’s deregistration process for the phone number.
This issue is especially likely when:
- Android-to-Android SMS works;
- iPhone users cannot reach you;
- the problem started immediately after leaving iPhone.
Do not reset Android network settings before checking iMessage registration.
Check RCS Status
If some conversations use RCS and others use SMS, check whether RCS is connected correctly.
In Google Messages:
Profile picture > Messages settings > RCS chats
Look at the status.
Possible states include:
- Connected;
- Connecting;
- Not supported;
- Disabled.
If RCS is stuck on Connecting:
- Confirm internet access.
- Update Google Messages.
- Confirm Google Messages is the default SMS app.
- Restart the phone.
- Check the status again.
Google also notes that changing messaging apps can disrupt message delivery if RCS remains registered incorrectly.
If you recently switched messaging apps or phones, turning RCS off temporarily and re-enabling it later can help re-register the number.
Check Notifications Separately From Message Delivery
Sometimes messages are arriving, but Android is not notifying you.
Open Google Messages and look for new conversations manually.
If the messages are there, the issue is notifications rather than SMS reception.
Check:
Settings > Apps > Google Messages > Notifications
Make sure incoming-message notifications are enabled.
Also review:
- Do Not Disturb;
- per-conversation notification settings;
- silent notifications.
Do not troubleshoot the carrier when messages are already reaching the inbox.
Update Google Messages
Google includes running the current version of Messages among its primary troubleshooting steps.
Open Google Play Store and update Google Messages.
Then restart the phone and test incoming SMS again.
If the issue began after a wider Android update and several apps are also unstable, see Apps Keep Crashing After Android Update.
Check Available Storage
Google states that Google Messages may fail to send or receive when the device does not have enough storage space.
Open:
Settings > Storage
If storage is critically low, free space before troubleshooting further.
Remove or move:
- large videos;
- offline downloads;
- unused apps;
- backed-up photos.
Use How to Free Up Storage Space on Android for a targeted cleanup.
Do not clear random app data just to make space.
Clear Google Messages Cache Only if the App Is Misbehaving
Cache clearing is useful if Google Messages:
- freezes;
- crashes;
- opens slowly;
- shows stale interface behavior.
Open:
Settings > Apps > Google Messages > Storage & cache > Clear cache
This should not normally delete your conversations.
Do not use Clear storage as an early fix.
For the difference between cache and app data, see How to Clear Cache on Android Without Losing Data.
If Only Verification Codes or OTPs Are Missing
This is often different from a general SMS problem.
If normal person-to-person texts arrive but one-time codes do not, check:
- Spam & blocked;
- whether the phone number entered on the service is correct;
- carrier short-code restrictions;
- whether the service temporarily rate-limited code requests.
Google notes that carriers can block short-code messages and that porting a number between carriers can temporarily disrupt verification texts.
If the same service keeps failing, contact that service and your carrier before resetting the phone.
If You Recently Ported Your Number
Number porting can temporarily affect incoming SMS even after calls start working.
The carrier may need to finish routing or provisioning the number for messaging.
This is particularly likely when:
- you kept the same number;
- you recently changed mobile providers;
- incoming texts fail from many senders;
- calls already work.
Ask the new carrier to confirm that inbound SMS routing and provisioning are complete.
Check Dual-SIM Settings
On a dual-SIM phone, make sure the line expected to receive the message is active.
Check:
- whether both SIMs are enabled;
- which line owns the number;
- whether the affected SIM shows signal;
- whether the SIM was recently switched, removed, or re-provisioned.
Incoming SMS should normally reach the correct line regardless of the default outgoing SIM, but a disabled or unregistered line cannot receive messages.
If one SIM repeatedly disappears or shows no service, troubleshoot the SIM first.
Test the SIM in Another Phone
If no incoming SMS arrives from anyone, testing the SIM in another compatible phone is a strong diagnostic step.
If incoming SMS also fails in the second phone
The likely causes are:
- carrier provisioning;
- SIM problem;
- account issue;
- network routing problem.
Contact the carrier.
If incoming SMS works in the second phone
The original Android phone or its software is more likely to be the cause.
That is a stronger reason to investigate the device than to keep blaming the carrier.
Reset Network Settings Only After the Targeted Checks
A network reset can help when the phone’s cellular configuration is corrupted, but it should come late.
Depending on the phone, look under:
Settings > System > Reset options
or:
Settings > General management > Reset
Choose the mobile-network or network-settings reset offered by your phone.
Read the warning carefully.
A broader reset may remove:
- saved Wi-Fi networks;
- Bluetooth pairings;
- mobile-network preferences.
If your saved Wi-Fi credentials matter, see How to Find Saved WiFi Passwords on Android before performing a broad network reset.
Contact the Carrier When Incoming SMS Is Still Missing
Contact the carrier when:
- no incoming SMS arrives from anyone;
- the same SIM fails in another phone;
- you recently ported the number;
- OTP and short-code messages are blocked;
- the line was recently activated or replaced;
- calls work but incoming SMS does not;
- the carrier recently changed account or SIM provisioning.
Describe exactly what works.
For example:
Calls and mobile data work, but I cannot receive SMS from any number.
That gives the carrier a much clearer provisioning problem to investigate.
Ask them to verify:
- inbound SMS provisioning;
- message routing;
- short-code blocks;
- SIM activation;
- account restrictions.
If You Can Receive but Cannot Send Messages
That is a different failure path.
Incoming and outgoing SMS can fail independently.
If messages arrive normally but yours will not send, use Can’t Send Text Messages on Android.
Keeping the two issues separate avoids changing settings that are already working.
