Common Causes of the “Message Blocking is Active” Error
The “Message Blocking is Active” error on iPhones can be triggered by several factors. Identifying the cause is the first step to solving the problem. Here are some of the most common reasons:

Unpaid Bills
If you’re using a prepaid plan, check that your account is active and that there are no pending recharges. For postpaid users, make sure there are no outstanding bills or payments. Unpaid bills can trigger the “Message Blocking” error when attempting to send new messages.
Do Not Disturb or Focus Mode
If the recipient has enabled Do Not Disturb (DND) or Focus Mode, you may experience this error. However, if the recipient is using Focus Mode, you’ll typically see the status in the Messages app.
Software Bugs
New iOS updates, especially iOS 16, have introduced several bugs that could cause this issue. Ensuring your device is running the latest software version can prevent these bugs from interfering with your messaging.

SIM Card Issues
Check that your SIM card is properly inserted into your iPhone. If you’re using an eSIM, ensure that it’s fully activated and has all necessary services enabled.
Network Issues
Temporary network problems, such as outages or poor connectivity, can also result in this error.

Account Restrictions
If your carrier detects violations of service terms, they may restrict your account, potentially causing the “Message Blocking” error. In extreme cases, your account may be suspended.
Troubleshooting Steps to Fix the “Message Blocking is Active” Error
1. Re-install the SIM Card
If you’re using a physical SIM card, try re-inserting it. If your iPhone was recently dropped, the SIM card might have shifted. Here’s how to re-insert it:
- Use the SIM ejector tool to remove the SIM tray.
- Align the SIM card correctly and re-insert the tray back into the iPhone.

If you’re using an eSIM, skip this step and proceed to the next one.
2. Reset Network Settings
Resetting your iPhone’s network settings can help resolve connectivity-related issues that might cause the error. Keep in mind that this will erase saved Wi-Fi networks and passwords, so make sure you have them handy. To reset your network settings:
- Open Settings on your iPhone.
- Select General.
- Choose Transfer or Reset iPhone.
- Tap Reset, then select Reset Network Settings.
Verify the Phone Number
Sometimes, we accidentally dial the wrong number, and this can happen with text messages as well. If you try sending a message to an incorrect or inactive phone number, you may encounter the ‘Message Blocking is Active’ error. Another common mistake is forgetting to include the country code at the beginning of the number.
It’s important to double-check the recipient’s phone number, including the correct country code, before attempting to send the message again.
Ensure You Have Active Cellular Service
Whether you’re using a prepaid or postpaid plan, it’s vital to confirm that your cellular plan is active and does not have any text limits, especially if you’re on a limited plan. If you’re on an unlimited plan, check that your carrier hasn’t imposed any restrictions on your messaging capabilities.
Unblock the Contact
If you’ve accidentally blocked the contact you’re trying to message, the ‘Message Blocking is Active’ error will appear. To fix this, follow these steps to unblock the contact on your iPhone:
- Open the Settings app on your iPhone.
- Tap on Messages.
- Select the Blocked Contacts option.
- Tap Edit in the top right corner.
- Tap the red minus icon next to the contact you wish to unblock, then select Unblock.
Disable iMessage on Your iPhone
Since iMessage and regular SMS/MMS messages are handled through the same Messages app, conflicts can sometimes cause the ‘Message Blocking is Active’ error. To resolve this, you can try disabling iMessage:
- Open Settings on your iPhone.
- Select Messages.
- Turn off the toggle for iMessage.
- Scroll down and turn on the toggle for Send as SMS.
Update Carrier Settings
Outdated or incorrect carrier settings can also cause the error. To ensure your iPhone has the latest carrier settings, follow these steps:
- Open Settings on your iPhone.
- Tap on General.
- Tap About.
- If there’s a carrier update available, you’ll see a red exclamation mark. Tap it and follow the on-screen instructions to install the update.
Update to the Latest Software Version
Bugs in recent iOS updates might be contributing to the issue. Be sure you’re running the latest stable version of iOS. To update your iPhone to the newest software version:
- Open Settings on your iPhone.
- Tap on General.
- Select Software Update.
- Install the latest software available.
Fix Date and Time Settings
An often overlooked but effective solution is to verify your iPhone’s date and time settings. Incorrect date or time configurations can occasionally cause messaging problems. Ensure that both the date and time are set correctly. After adjusting them, try sending your message again to see if the issue is resolved.
Contact Your Carrier
If the error persists, your next step should be to reach out to your carrier for assistance. Explain the situation and ask if any message-blocking restrictions have been applied to your account. Your carrier will be able to investigate and help resolve the issue.
Contact Apple Support
If none of the above solutions work, it’s time to contact Apple Support. You can either call their helpline or visit your nearest Apple Store for further assistance.
