Xfinity Mobile – Outgoing SMS/Calls to Unsaved Numbers and Short Codes Failing

Hello Xfinity Mobile Support,

I am contacting you regarding my Xfinity Mobile number [Edited: "Personal Information"]. I have two mobile lines under my account, and this is the specific line experiencing the issue.

On this line, I am having problems calling and sending SMS messages to numbers that are not saved in my contacts. I am also unable to send SMS messages to short-code numbers. For example, when attempting to send a message to [Edited: "Personal Information"] (FIGS), the message fails and displays “Not Delivered.”

I have already checked the relevant iPhone settings. Screen Time → Communication Limits is set to Everyone, and removing/turning off the relevant restrictions did not resolve the issue.

Please investigate the carrier/network provisioning for [Edited: "Personal Information"] and:

1. Verify that voice, SMS, and MMS are fully provisioned on this line.
2. Check for any blocks or restrictions affecting short-code SMS, premium messaging, or communication with unsaved/unknown numbers.
3. Check for any other network-level calling or messaging restrictions on this specific line.
4. Reprovision/refresh the voice and SMS services on this line if appropriate.
5. If the line appears correctly provisioned but the issue persists, please escalate this to Xfinity Mobile Advanced Technical Support/network support.

Please note that I have two numbers on my Xfinity Mobile account, so please make sure troubleshooting and any reprovisioning are performed specifically on [Edited: "Personal Information"], not my other line.

I can provide screenshots showing the failed SMS and “Not Delivered” error. Please also provide me with a case/ticket number for this issue so I can reference it if further follow-up is required.

Thank you.
