No SMS Connectivity

[Raymond2]

I'm reaching out for some technical advice,

2022 Chevy Silverado Z71 package current mileage 6303

The last time the truck uploaded to the My Chevrolet app was 1-27-24 @ 4512 miles 

Ruffly 1 month ago I reached out to On Star to seek help with the My Chevrolet App I was advised to take the 2022 Chevy Silverado and have the Telematics checked for operation

On Star system was checked and it was discovered that code DTC U0198 was present “No Communications to Telematics module”

This morning the local Chevrolet dealer in Fort Collins replaced and programmed a new 86581706 Module 9.675 Telematics module 

The truck will communicate with On Star However On Star will not communicate with the My Chevrolet app

I was still at the Chevrolet dealership and had both the service advisor and the technician who replaced the Telematics Module speak to the On-Star advisor both dealership employees were told the truck was not sending out an SMS signal 

On-Star advisor had me uninstall my app and delete my account 

On-Star set up a new account and charged me for a new subscription 

My 2022 Chevrolet does not communicate with My Chevrolet app

The Dealership has the ability to check for SMS communication

Helen,

As discussed over the phone it took 4 OnStar advisors to finally get this issue resolved, the root cause of this problem was the dealer replaced the Telematic Control Module once the module was replaced the dealer reached out to OnStar to program the new module and it was not done correctly
