Despite many modern alternatives, SMS messaging apps are still a standard tool. This is why we can understand how frustrating it can be when you’re having issues with a messaging app not working. Thankfully, most problems can be solved with a bit of troubleshooting, and we’re here to help with that.
Editor’s note: Some of the instructions in this article were generated using a Pixel 4a with 5G running Android 12. Keep in mind that steps can be slightly different depending on the device you’re using.
1. Outages and reception

While very uncommon, there is a chance your carrier network is having an outage. This could be why you have problems with your messaging app not working. Some carriers may have status pages, and they often send announcements when there are any widespread issues.
Another way to check is by using an online tool like DownDetector.com. Just enter the website and search for your carrier name. This website collects user reports and lets you know if there is an outage. You can even check out their live maps, which show if any local outages are going on.
There’s also a chance you have no signal. This is a common issue when you are driving through country areas or inside a concrete building with no reception.

2. Is Airplane mode on?

It may seem like a silly suggestion, but you have no idea how often we accidentally switch settings on and off. Maybe you turned Airplane mode on, which will obviously stop Messages (and pretty much any other app) from working.
How to turn Airplane mode on/off:
- Open the Settings app.
- Go into Network & internet.
- Toggle Airplane mode.
3. Restart the phone
This is a very common troubleshooting tip. While it may sound a bit silly, it very often works! We don’t know what kind of magic happens when you restart a phone, but it’s worth a shot. You can do this by pressing and holding on to the power button. Then press the Restart option. Obviously, you can also go all the way and shut the phone down and then turn it back on.
4. Check your mobile plan

There is always a chance you forgot to pay your monthly cellphone bill. It happens to the best of us. Additionally, automatic payments can sometimes be declined for no apparent reason. This may have happened to you. If the tips above didn’t work, it doesn’t hurt to head into your carrier’s website and see if your account is in good standing.

5. Clear the cache and data
Cache data is good for keeping your device snappy. It is locally stored and ready to use when needed, instead of downloading information every time it’s accessed. The only issue is that cached data can also get corrupted, especially if the files are older. It’s good to clear all cache and data now and then. This gives your messaging app a fresh restart. The only downside is you’ll have to set it up again.
How to clear cache and data on Android:
- Open the Settings app.
- Go into Apps.
- Find the Messages app under See all apps.
- Tap on Storage & cache.
- Hit Clear Cache.
- You can also select Clear storage for a clean start.
6. Inspect the SIM card

Sometimes SIM card pins can get out of line. It’s a good idea to check the SIM card and see if that gets your messaging app up and running again. Pull it out and reinsert it. Maybe try to clean it a bit? It won’t hurt to try!

7. Did you recently install any new apps?
Believe it or not, sometimes downloading an app can mess up the workings of other apps on your phone. If you recently downloaded and installed a new app, and you’re still having issues with a messaging app not working, deleting the third-party app might be the solution.
How to delete Android apps:
- Find the app you want to delete in your app drawer or home screen.
- Tap and hold on to the app.
- Select App info.
- Hit Uninstall.
- Confirm by hitting OK.
8. Reset the network settings

Sometimes resetting the network settings may fix any issue with your messaging app not working. This is because SMS messaging operates directly through your carrier network instead of mobile data. Resetting the network settings will get everything back to default and undo any discrepancies.
How to reset network settings:
-
- Open the Settings app.
- Select System.
- Go into Reset options.
- Hit Reset Wi-Fi, mobile & Bluetooth.
- Tap on Reset settings.
9. Factory reset your phone
This is an extreme measure, but it fixes most issues, and it might get your messaging app back in working order. A factory data reset will wipe your device clean and bring it back to the way it was when you first turned it on. All your files and apps will be deleted, so make sure to backup all your important data before going on with this.

How to factory reset your Android phone:
- Open the Settings app.
- Select System.
- Go into Reset options.
- Hit Erase all data (factory reset).
- Tap on Erase all data.
- Follow instructions to finish the process.
If you’re still having issues with your messaging app not working, maybe it’s time you let a professional help you out. You can go to your carrier and seek assistance. Your phone’s manufacturer might help too. There are also third-party options. You can connect one-on-one with an electronics expert through JustAnswer, an Android Authority partner.
10. Seek professional help

If none of these fixes help, it’s time to seek professional help. The best option is likely to go with your carrier. They will provide both network and hardware support, and also have access to their systems, which probably have more in-depth information that could help.
You can also reach out to your phone’s manufacturer, or your insurance provider if you have one.
