Mobile carriers (Verizon, T-Mobile, AT&T, Sprint, etc) have different words for a delivered text message

Here are a few examples:

  • Delivered = Delivered
  • En Route = Delivered
  • N/A = Delivered
  • Delivered To Carrier = Delivered
  • Buffered = Delivered


In short, everything in the delivery status means delivered except the word FAILED. 

  • Failed Messages


There are 2 main reasons why a message would fail, a carrier change or a short code block.


Carrier Change: If a contact has switched mobile carriers, it is not something that they'd come into your office and shout from the rooftop "I SWITCHED FROM AT&T TO VERIZON AND IT IS AMAZING!!!"  You might hear, "I used to get your messages (or appointment reminders), but I don't anymore....why not?"  This is usually due to a carrier change. 


Zingit does an official carrier lookup when we import everyone into the account. The carrier will notify you with a failed message when they are unable to deliver it to the persons phone. The next step is to recheck their mobile carrier.  The video below will show you how:




Short Code Block:  The second reason a message is not delivered, is if the account has a short code block. This is less common but the account holder can dial 611 from their cell phone.  This will connect them to their provider and they can ask them to remove the short code block.  There is no charge to them to do this and it only takes a few minutes.
