If your Android smartphone displays the message “IMS registration status not registered,” you can neither make calls nor surf the Internet. Samsung users are quite familiar with this.
The IMS (IP Multimedia Subsystem) service on your Android smartphone is a framework for providing multimedia communication services like voice, video, and text messaging through IP networks.
When you start your device and see “IMS service stopped” or “IMS registration status not registered,” all these services would not be accessible. Of course, the causes can be different, but the problem is solvable. So, first, I’ll show you the possible reasons you’re having this problem and what to do.
What Causes “IMS Registration Status Not Registered”?
If you’re getting the “IMS registration status not registered” message and your phone networks aren’t coming up, the causes are most likely one of the following:
1. Your phone’s firmware or OS
An out-of-date operating system or firmware can cause this problem. Your phone needs the latest OS and firmware to work as it should and eliminate bugs. Keeping your mobile or tablet updated is crucial to avoid security issues and improve privacy.
2. Disconnected or damaged SIM card
The error message can come up if your SIM card is improperly placed. Therefore, you won’t be able to make calls, receive messages, or have internet access.
3. Your SIM card or local area doesn’t support 5G
Some users have mentioned this problem when switching to higher network modes like 5G or 4G. Also, if you just changed location or you were traveling, and this problem kicks in, then it could be that the area doesn’t have support for higher network modes. You will most likely resolve the issue if you switch to 2G or 3G.
4. Network carrier not selected
If your network carrier isn’t selected for calls, messages, or data, you may not be able to use that service. Sometimes, you must manually select your carrier’s network in the phone settings.
Tips to Fix “IMS registration Status Not Registered”
Here are some steps I suggest you take to fix the problem. After each step, check if the error has been resolved:
Fix 1. Update your OS
The pop-ups that remind you to update your operating system can become annoying. However, operating system updates are still useful. They correct errors in the OS and help to improve its usability.
First, I’ll show you what you need to pay attention to before starting an OS update.
Requirements for a software update
Downloading and installing new software is a complex process that drains the battery. So, make sure you are on the safe side here. Your battery should be charged up to at least 50%.
Second, for a software update, you may need a WiFi connection. OS updates need a few gigabytes to be downloaded. A WLAN connection generally allows a much higher data transfer rate.
How to make an OS update
The easiest way to perform a software update is to do it directly on your smartphone. This can be done in two different ways.
You either get a pop-up window saying a new software update is available. In which case, follow the instructions in the infobox, and the software update will be completed in a few moments.
Or you can initiate the Samsung software update yourself. Of course, this only works if a new version of Android is available for download.
In this case, do the following: Tap Settings >> Options >> Device information >> Software updates >> Update now. Before you can use the updated software, your device must first be restarted.
If no software update is found, you probably already have the latest Android version.
Fix 2. Reset your network settings
Since this is a problem with the network setting from your phone or your network provider, you may want to be sure the problem isn’t coming from your end.
If you’ve tried all of the above, reset your network settings. However, note that all your WiFi passwords will be erased.
How to reset your network settings
Since Samsung Galaxy users mostly encounter this issue, I’ll be showing you how to reset Samsung Galaxy network settings:
- Step 1: Slide your finger up on the screen. This will display a list of all apps on your phone.
- Step 2: Your applications may be displayed on several pages. Scroll left or right to move between pages.
- Step 3: Open the Settings app with an icon that looks like a cogwheel. Note that the Settings menu icon may be different if you use a different theme.
- Step 4: Tap on General Management. This option is at the bottom of the Settings menu.
- Step 5: Select Reset. The Reset option is down the General Management menu and displays the reset menu.
- Step 6: Select Network Settings Reset. This is the second option in the reset menu. Tap it to bring up a page telling you that your WiFi, mobile data, and Bluetooth settings will be reset.
- Step 7: Tap on Reset Settings which is in a blue button. It will redirect you to a confirmation screen. If you have a passcode or PIN, you’ll need to enter it before you can continue.
- Step 8: Select Reset Settings. This option confirms that you want to reset your network settings and settings.
Fix 3: Switch to a lower network mode
If you’ve just changed location, you’re on the go, or you suspect the network provider has issues with your current network mode, try switching to a lower network such as 3G.
To do this, go to your Settings >> Connections >> Mobile networks and select a Network Mode.
You may also want to confirm if other phones with the same network have the same issue as you do.
Fix 4: Check your SIM card
As I mentioned earlier, a mispositioned or damaged SIM card may cause this problem. So, switch off your phone and check the SIM card.
If it’s not damaged, position it well on the metal tray and restart your phone. If the SIM card is damaged, you must make a SIM replacement.
Fix 5. Clear cache partition
First, try clearing your smartphone’s cache partition. To do this, go to the “Settings” of your device and open the “Application Manager” or the “Apps” area.
Look for the entry “IMS Service” here. Select it, then tap Clear Cache and Clear Data. You can then restart your device.
Fix 6. A reset as the last solution option
If nothing helps, it may be necessary to reset your device to the factory settings. However, since all data will be deleted from the device in the process, you must create a backup beforehand.
Then you can reset your Android smartphone from settings by going to “Backup and restore” and selecting “Erase all data.”
