What does "Channel Rejected" under Bounces mean.  And, how do I fix that?

Hello @SteveD34 ,

"Channel Rejected" is a general bounce type we use for a few different technical codes as provided by Sinch. 

It looks like our higher level technical teams are already working on pulling the exact error codes that resulted in your SMS campaign's "Channel Rejected" bounces. Per their email yesterday morning, they'll be following up within the next few business days with those exact codes.

The more general understanding is that "Channel Rejected" is caused by the receiving network throttling or spamming out the message in a way that it doesn't go through. It's the contact's network saying they won't let the message through based on how their system views the text message. For an email comparison, it's like the Blocked bounce.

As far as correcting it, there may be some variance depending on the exact codes. Generally speaking, "Channel Rejected" means that your SMS messages won't be accepted by those contacts' networks, and they should be removed as SMS contacts.

Thank you for the info.  I'll await the deeper dig into this as you suggested.  Since posing this question, I have sent another SMS to 15 people and 6 of those including my own cell phone number are creating the same "rejected channel."  One number was tagged "recipient not reachable" so I hope there is a solution since nearly half to the recipients don't receive the texts.  I'm assuming that there are just still bugs to work out and I appreciate your help with this.  Thanks, Steve

THIS!!  This is my issue.  Just today (4.21.25) I sent a text w/a link to 129 recipients. 89 delivered, 40 bounced. 

• 1 Bad Channel Configuration
• 24 Channel Rejected
• 15 Recipient Not Reachable

How can this get fixed??

Half of my email list DO NOT read email. Text is the ONLY way I can get them to check their email!!
HELLLLP !!

Hello @SRFDC ,

I've submitted your case to the higher level technical team to get the exact codes from Sinch, and follow-up with you via email in the next 4 business days. There's been issues gathering the info from Sinch, so they can't guarantee their immediate follow-up will have the exact error codes.

We are also having this issue. We were at a 99% delivery rate, then I started using links to be able to send more info out, and the delivery rate has dropped over 30% and showing channel rejected. Are these messages counted towards our SMS total of being charged even if they're bouncing? Do we just need to stop sending links?
