Several users have reported that the iOS 9 update on iPhone or iPad appears to be causing serious problems for their Messages and iMessages. It seems that some users are experiencing a few annoying problems since updating to iOS 9 with Messages not working properly. If you have already updated to the latest iOS 9, and are having issues with Messages, here is how you can troubleshoot those issues.
Before we start, please note that the following eight tips may fix most issues
- Resart the Messages app by double tapping the Home button then swipe to the app to force quit. This action will force quit the Messages app. Don’t worry you will not loose any data or messages. Then relaunch the Messages app.
- Restart your iOS device by pressing and holding the off/on button until you see the slider. Then slide the slider to turn off your device.
- Turn on Airplane Mode and turn off by going to Settings > Airplane Mode.
- Turn off and on iMessage by going to Settings > Messages
- It is likely that a connection problem may causing this problem. Resetting network settings may fix this. Simply Tap > General > Reset > choose Reset Network Settings.
- Some users stated that turning off Wi-Fi Assist fixes this problem. If you want to try this tip, go to Settings > Cellular > and turn off Wi-Fi Assist.
- Make sure that the Date and Time setting is chosen “Set Automatically” by going to Settings > General > Data & Time.
- You may try to change your DNS settings and try again if this solves your iMessage problem. To do this, tap Settings > Wi-Fi. Locate your wireless connection then tap the (i) button. Now tap the DNS field and enter 18.104.22.168 (this is Google’s public DNS).

Problem sending or receiving messages
After updating to iOS 9, you may experience problems when sending or receiving messages. Your messages may show as sent but fail to get delivered. Your messages may also appear as blue on the iMessage and show as not delivered, but you get a response from the person you sent the message to.
This problem can occur in both single and group text messages, but seems to affect group texts most often. If you have this problem, try hard restarting your phone, toggling the iMessage application on and off, and restoring the device to factory settings. If these steps do not solve the problem, try turning off Wi-Fi Assist. These problems may occur due to a glitch in the system.
Delayed text messages
If you recently updated your iPhone or iPad to iOS 9, you may be experiencing delayed messages. When you use iMessage, you may find you are not receiving messages until several hours after they have been sent. Conversely, your recipients may not get your sent messages until hours later. You may receive a ‘text delivered’ notice, but the receiver does not receive the message immediately. This problem usually occurs if your phone number is not checked on the FaceTime app.
You can solve these ‘delayed message’ problems by changing your phone’s settings. Go to Settings and access the FaceTime app. Turn the FaceTime app off, then back on, and tap ‘use Apple ID for FaceTime.’ Your phone number will show a solid check and your iMessage should start working properly.
Friends receiving the same iMessage twice
When sending an iMessage to your friends, it may be delivered two or three times without your knowledge. If you have this problem, try turning your mobile device on and off, hard restarting it, and resetting it to the factory setting. If this still does not solve the problem, try resetting your phone’s networking features under Settings. You may also try to turn off and then on your iMessage app to solve the problem. If you continue to experience the same problem, you can contact Apple to see whether they have found a solution.
iMessage sound goes off twice in a row
Sometimes you may hear the iMessage sound twice in a row after updating to iOS 9. This sound can be annoying if the problem is not solved. To solve, go to Settings -> Messages, and turn off iMessage. Reboot your phone, wait for one hour, and then turn iMessage back on. If the annoying repeating sound comes back again, try activating and deactivating the Repeat Alert setting. If the problem is not solved, try turning the iMessage app off and on.

‘Service Denied’ text message from ‘Unknown’
Another iMessage app problem with the iOS 9 update is receiving a ‘Service Denied’ text message from ‘Unknown.’ If you keep receiving this kind of text message, report the problem to your carrier. The problem may have nothing to do with Apple. However, users who have been reporting this problem to their carriers often get referred to Apple.
Troubleshooting tips for this issue include backing up your phone, restoring it to its original factory setting, and then sync with iTunes to regain your apps, music, pictures, and other files. Remember when restoring your device to restore it as a “New Device.” Don’t try restoring from “back up” or you will end up with the same problem. Also, ensure you sync your phone with iTunes before wiping your files.

Problems with deleting Unknown messages on the iMessage app
Another problem you may encounter after you have updated to iOS 9 is difficulty in deleting “Service Denied” text messages. One of the solutions is calling your mobile operator, who will give you the SMS center number and dial code to help you identify the source of the text message.
You will need to make sure you are using the SMS center number and dial code provided by your mobile operator. If you are using a wrong SMS center number, call your service provider and request them to reset your network. After they have reset your device’s network, restart your phone. You should not see any more “Unknown” messages.
I don’t usually experience these issues while using both Messages and iMessage features. However, some users might configure something differently, and that may lead to these problems. Let me know if you still need help.
