Error codes returned by the carrier on SMS or MMS
You might receive error codes returned by the telephone carrier after you’ve sent a SMS or MMS.
The telephone carriers filter all the messages to protect the mobile subscribers from spam and other forms of unwanted messaging.
And, these systems look at both message content and volume.
Filtering in the United States and Canada can affect the delivery of your SMS and MMS messages.
