Fix: Message Blocking is Active

Furthermore, after sending a message, users have been receiving the “Unable to send a message – message blocking is active.” problem. T-Mobile seems to be the most common source of this error message.

In this post, we’ll look at some of the causes of this issue and the workable solutions we found to eradicate it once and for all.

Message Blocking is Active


Open up Premium SMS Service

Some messaging apps can’t function without premium membership so that users can send and receive messages. So, in this step, we’ll enable Premium Access for the messaging app we’re using in the configurations. Due to this:

  1. Bring down the alerts tray and hit the “Settings” button.
  2. The “Apps” tab can be accessed by first clicking the “Application” tab.
  3. To access the menu, select the “Three Dots” in the upper right.
  4. Go ahead and pick “Special Access” from the drop-down menu.
  5. A “Premium SMS Access” button should be selected.
  6. To grant permission, find the app in question and click the “Ask” button.
  7. See whether the problem still exists.

Get In Touch With Tech Support

Only the technical team at your carrier’s customer care hub can come up with the best solution to this problem. A T-Mobile customer who used Twitter to get in touch with the company’s support team received the following response, which describes the nature of the problem on that particular carrier:

“Gotcha! I appreciate you sharing your account details with me. I’ve modified the short codes that normally trigger this problem. It seems to have been set to block some time in the past three years.

I was hoping you could retry the problematic text and report back with the results. I appreciate your assistance. This points to a purely technical issue that can be resolved by customer assistance.

Error: “Unable to Send a Message – Message Blocking is Active.”

Due to the high volume of user complaints, we decided to look into the matter and come up with a plan to fix it once and for all. We also investigated the causes of its occurrence and compiled them in the following.

This error most likely occurred because of a temporary disruption in service from the service provider. It’s possible that the error you’re seeing is the result of a brief maintenance interruption, during which the messaging service was put on hold.

The primary reason for the message is that the recipient is on the sender’s block list, or vice versa. It’s important for both parties to check each other’s blocked numbers to make sure they’re not on each other’s lists. Also, make sure your phone calls to them go through smoothly.

Access to Premium Messages: The user may have disabled sending and receiving premium SMS messages on his cell device. Some messaging apps rely on this service, hence enabling it is necessary for proper operation of those apps.
