If you’re seeing “Free Msg: Unable to send message – Message Blocking is active” when trying to send a text, this guide will help you fix the “Message Blocking is active” error so you can resume normal texting.
Before diving into the solution, ensure you have a smartphone (Android or iPhone), access to your carrier account, and an internet connection. These are the basic prerequisites to troubleshoot and resolve the issue.
To resolve the Message Blocking is active error, follow these troubleshooting steps to identify and correct the cause of the Message Blocking error on your device. First, check your phone’s block list. For Android devices, open the Phone app, tap the three-dot menu, go to Settings → Blocked numbers, and tap the X on any number to unblock it and confirm. For iPhone, open Settings → Phone → Block Contacts, tap Edit, tap the red minus sign next to any number you want to unblock, then tap Unblock and Done. Also, verify that the number isn’t blocked at the carrier level.
Try texting somebody else to see if the problem is limited to one contact. It’s also essential to make sure you have cellular service, as SMS requires a working cellular signal. Restarting your phone can also resolve the issue; power it off, wait a few seconds, then power it back on and allow it to reconnect to the network.
Disabling message blocking for your account is another step. Sign in to My T-Mobile, go to My Profile → Blocking controls, select your phone number, uncheck “Block sending and receiving SMS/MMS”, and save. Ensuring your account is in good standing by confirming that your bill is paid and your payment information is up to date is also crucial.
Temporarily disabling Wi-Fi calling can help. For Android devices, open Settings → Connections (or SIMs) → Wi-Fi Calling and toggle off. For iPhone, open Settings → Phone → Wi-Fi Calling and toggle off “Wi-Fi Calling on This iPhone”. On iPhone, turning on Send as SMS by going to Settings → Messages and enabling Send as SMS can also resolve the issue.
For Android devices, clearing the Messages app cache can be beneficial. Go to Settings → Apps → See all apps → Messages → Storage & cache and Clear cache (or Clear data if cache isn’t available). Switching to Google Messages on Samsung Galaxy devices by installing it from the Play Store and setting it as the default texting app is another potential solution.
Ensuring your SMSC number is correct is vital for Android users, especially for T-Mobile, Mint, Metro, and Boost, where the SMSC should be +12063130004. Verify it in the Messages app under Settings → More Settings → Text messages → Message Center. Resetting your APN settings can also help; for Android, open Settings → Connections (or Wireless & networks) → Mobile networks → Access point names → three-dot menu → Reset access points (or Reset to default). For iPhone, open Settings → Cellular → Cellular Data Network → Reset Settings if available.
Checking your APN settings on Android is also necessary. Ensure the APN value is Fast.t-mobile.com (LTE) or epc.t-mobile.com (non-LTE). Set Proxy, Port, Username, Password, Server, Authentication Type, MMS proxy, and MMS port to “Not set”. Use http://mms.msg.eng.t-mobile.com/mms/wapenc for MMSC and default,supl,mms (stock Android) or Internet+MMS (Samsung) for APN type, then save and restart.
If none of the above steps resolve the issue, contacting your cellular provider is the next step. Confirm that texting is enabled, you haven’t reached a limit, and there are no account blocks. As a pro tip, if the error persists after all steps, try resetting your phone’s network settings to clear any lingering configuration issues.
Resolving the Message Blocking error restores your ability to communicate via SMS, which is essential for everyday coordination, emergency alerts, and verification codes that many services rely on. Keeping your carrier settings and account in good standing also helps prevent future disruptions and ensures you stay connected without unexpected service interruptions.
