What is necessary to get ATT Wireless to update CNAM.
We obtained a phone number in April 2022 that was previously used by a different company. We obtained the number through Twilio. We changed the CNAM at that time. Today (11/28/22), ATT Wireless customers still show the old CNAM while Verizon and TMobile show the new (correct) CNAM. What do we need to do to get ATT Wireless to update the registry?
Phone Number: 844-427-6527
Correct CNAM: "Sunergy" or "Sunergy Solutions"
Old/Incorrect CNAM: "Canopy Energy"
