11 Tips to Fix "Message Blocking Is Active" iPhone Error

Sending text messages is usually straightforward, but sometimes you may encounter problems like the Message Blocking is active iPhone error.

So, how can you fix it and resume sending messages on your iPhone as before? We will show you. Herein, you'll learn what causes this Message Blocking is active iPhone error to pop up and also discover 11 effective solutions for fixing it completely. Read along to uncover all these.

What Does Message Blocking Is Active iPhone Mean?

When you send a message, and you get an error message that says, "Unable to send message - Message Blocking is active," it means you've blocked the recipient – you've added their phone number to your backlist, and as such, your phone can't send message to that number. It can also mean your phone cannot send the message because the phone number or email address is wrong.

Now that you know the meaning of Message Blocking is active, start sending messages again by fixing the error using the following simple methods.

1. Verify the Phone Number

You may enter the wrong number without knowing when you try to send a text quickly. Maybe only one digit is wrong, or probably the country code. This simple mistake can cause the “Unable to send message - Message Blocking is active” iPhone error to pop up. So, first, verify the phone number before trying anything else.

2. Check Your Cellular Plan

You can't send test messages if you don't have an active cellular plan. If you do, but the error message still pops up, you may have reached your monthly text message quota limit – unless you're subscribed to an unlimited plan. Therefore, verify your plan; if it's exhausted, renew it, and the error will disappear.

3. Remove the SIM Card and Re-insert It

Skip this step if you have an eSIM on your iPhone.

The Message Blocking is active iPhone error could pop up because your SIM card is not set properly. This means if you take out the SIM card, set it properly in the tray, and put it back in the phone, you may fix the error – ensure you also clean the SIM card and there is no dirt on it before putting it back.

4. Unblock the Blocked Number

Does the error show up when you send a text to a particular contact? You may have unintentionally blocked that phone number. You can confirm this by checking the blocked contacts list on your iPhone. Follow these steps:

  • Get to Settings. Select the Phone option and tap on Blocked Contacts.
  • Select the Edit option (upper right corner). Go to the red minus sign next to the number or contact and tap it.
  • Tap on Unlock on the right end and finally tap on Done to finish.

With the number unblocked, go to the Messages app and try re-sending the message.

5. Turn Off iMessage

Both iMessage and regular SMS on iPhone are sent from the Messages app. Because of this, conflicts and errors between the two services can sometimes occur – this may be why you're getting the “Unable to send message - Message Blocking is active” iPhone error. You can rule out this possibility by turning off iMessage and see if it resolves the issue.

  • Launch Settings and open the Messages tab.
  • Go to iMessage and tap the switch in front of it.

You've now disabled iMessage, so check if you can send messages.

6. Fix Incorrect Date & Time

Your iPhone's date and time have to always be correct. They should not be different from your region's actual date and time; otherwise, your iPhone may have issues like this Message Blocking is active error. Many services on the phone can stop working, too.

So, what should you do? Look at the date and time settings. If they're incorrect, we suggest you activate the Set Automatically option. To do that:

  • Head to Settings. Open the General tab.
  • Go to Date & Time and enable the Set Automatically option.
