Are your messages at risk of getting lost along the way?

“Wait… not all of my messages are getting delivered?! Why not?”

How does a message get delivered?

Every message travels across an elaborate web of interconnected carrier networks encountering a number of checkpoints. Carriers like Bandwidth use these checkpoints to check for SPAM and protect consumers from unwanted text messages.

The Criteria affecting message delivery

There are a lot of criteria that determine whether or not your message will be delivered. Different carriers may evaluate your message differently, and the rules they use can be subject to change at any time. But, in general, they look at a common set of criteria when deciding whether or not to allow your messages on their network.

The Sender

  • Who is the sender?
  • What number are they using?
  • Have either been flagged for SPAM in the past?

How they are sending

  • What type of number are they sending from?
  • Is it a short code, toll-free, or a local number?
  • Are they sending person-to-person or high-volume, application-to-person (A2P) messages?

How to know when, where, and why messaging failures happen

Status and error codes help you understand which messages didn’t reach their final destination, where they were stopped, and why. But not all error codes are created equal. Make sure you’re getting confirmation that your message actually made it to your recipient’s phone— not just the end carrier.
