What does “Message Blocking Is Active” mean?

When you encounter the “Message Blocking Is Active” error on your iPhone, it means your phone can’t send a text message.

Let’s understand the reasons in detail!

Why is “Message Blocking Is Active” appearing?

Your iPhone may be unable to send messages due to several factors such as:

  • Blocked contacts: You might have mistakenly added the recipient’s number to your block list, or the recipient may have blocked your number. In such cases, messages cannot be exchanged between the two numbers.
  • Carrier restrictions: Your carrier may have limited your messaging activity because of billing problems, outages of their service network, or your plan itself. For example, some data-only plans don’t support SMS messaging.
  • Service outages: This error can also be caused by temporary service outages or maintenance by your carrier that is preventing messages from going through.
  • Short code problems: If you’re a T-Mobile customer, problems with short codes—numbers that businesses use—can lead to this message-blocking issue.
  • Incorrect message settings: Message settings such as disabled SMS, MMS, or iMessage options can block message sending.
  • Wrong date and time: If your iPhone’s date and time settings are wrong, it may fail to communicate to servers and send the message.
  • System glitches: Bugs and glitches in the Phone app or iOS system can interrupt the messaging services.

Understanding these potential causes can help you quickly diagnose and resolve the “Message Blocking Is Active” error on your iPhone.

We will guide you through step-by-step solutions to fix the error message. You can follow them in order until you find the one that works for you.

1. Unblock the contact

If you have the intended recipient blocked, you may receive the “Message Blocking is active” status. Here’s how to check:

You have successfully unblocked the contact and can proceed to send them a text message.

If you don’t see the number in this list, they may have blocked you instead. For more information, see our guide on how to tell if you’ve been blocked on iMessage. The easiest way to check this is to mask your caller ID by dialing *67 before entering their number.

2. Check the phone number

If you accidentally enter the number incorrectly in a hurry, you may receive the “Message Blocking is active” text when trying to send a message.

So, before we proceed to the next step, re-check the recipient’s phone number and make sure you’ve entered the correct digits.

3. Disable iMessage

There’s a chance you’ve come face to face with an iMessage glitch. If that’s the case, flipping iMessage off and on again could be the simple fix you’re looking for. Here’s how:

  1. Open the Settings app → Navigate to Messages.
  2. Turn off the iMessage toggle. 

    To disable iMessage go to Settings navigate to Messages turn off the iMessage toggle

Now that you’ve disabled iMessage, try sending the text through SMS. If you are still getting the “Message Blocking is active” message, move on to the next step.

Note: You can re-enable iMessage through the same place, SettingsMessages.

4. Check your SIM card

Remove and reinsert SIM on iPhone

If you have switched to eSIM, you can skip this step and move on to the next one.

If you still use a physical SIM and are facing the “Message Blocking is an active” error, check if you’ve inserted the SIM card correctly.

First, eject the SIM tray out of the slot using a small, thin object like a paper clip. Align the SIM card correctly with the SIM tray, then reinsert it into your iPhone.

You can also restart your iPhone if you cannot see the cellular network icon.

5. Fix Date and Time settings

Your iPhone’s date and time settings should always be set accurately. If they’re different from your region’s actual date and time, many services may cease to work as intended.

If your iPhone’s date and time settings are inconsistent, we recommend enabling the Set Automatically option in Settings.

  1. Open the Settings app → General.
  2. Select the Date and Time option. 
  3. Turn on the Set Automatically toggle

    Fix Date and Time settings go to Settings navigate to General select Date and Time turn on the Set Automatically toggle

Check if you can send a text. If you’re still getting the “active blocking” message, check your carrier settings.

6. Update carrier settings

Cellular network providers, aka carriers, push out updates to the network that help improve connectivity, performance, and more. These updates also enable features like 5G and Wi-Fi calling. Follow the steps mentioned below to update the carrier settings on your iPhone.

  1. Open SettingsGeneral.
  2. Tap About.
    Update carrier settings go to Settings navigate to General tap About

If there are any updates, you should see a red icon beside the About option. If there is a new version, a pop-up will prompt you to update. Follow the on-screen instructions, and you’re good to go.

7. Update to the latest iOS version

Another possible reason you’re receiving the “Message Blocking is active” status is an iOS software bug.

Update your iPhone to the latest stable iOS version to ensure there is no software issue causing this problem.

  1. Open SettingsGeneral.
  2. Tap Software Update
    Update to latest iOS version go to Settings navigate to General tap on Software Update
  3. If an update is available, tap the Download and Install option at the bottom of the screen.

Give that text another crack. Still no dice? Then it may be time to reset your Network Settings.

8. Reset Network Settings

Sometimes, issues arise in your iPhone’s Network Settings that you can’t resolve with the usual solutions. In such cases, it’s best to reset your iPhone’s network settings.

  1. Open SettingsGeneral.
  2. Scroll down and select Transfer or Reset iPhone

    Reset Network Settings go to Settings navigate to General select Transfer or Reset iPhone
  3. Tap Reset and select the Reset Network Settings option.
    Tap Reset and select the Reset Network Settings option
  4. Now enter the iPhone’s passcode to reset all the Network Settings.

This will NOT delete any photos, videos, or files on your iPhone. However, it would still be wise to create a backup beforehand.

9. Verify your cellular plan details

You need an active cellular plan to send text messages. If you have an active plan and are still facing this issue, please check if you have exhausted your text message quota (if you aren’t on an unlimited plan).

If your plan has expired, renewing it will resolve the “Message Blocking is active” error.

10. Contact your carrier

If none of the above troubleshooting methods helped you resolve the issue, you should try contacting your carrier and asking for a solution. This problem may be specific to your carrier, and they might not have noticed it yet.

You can contact your carrier on their respective website or through their support number. If the support team is aware of the issue, they will likely be able to resolve it.

11. Contact Apple Support

Contacting Apple Support should be the last resort for all issues. They tend to have solutions. At the very least, you’ll get an idea if the issue is widespread or explicitly affects your device.

Additionally, if a hardware problem is causing this issue, you can get it fixed if your device is under warranty or if you have subscribed to an AppleCare+ plan. Head to the nearest Apple Store or contact Apple Support.
