I'm at a loss as where to start with this. When I call my son's cell phone I get a Subscriber Not in Service Message with a variety of Message numbers. On the first call it was FL?4256, the second time that message played on that call the message number was CA19156. I hung up and made another call--first code CA12656, second playing on that call was CA19156.

Both of us have cell phones on US Mobile in a pooled plan. I have no issue calling him on his cell from my cell and he doesn't have an issue calling me on my cell or on the landline.

I read one possible solution was for him to call the landline and then I would be able to call him after that but that didn't work. I'd appreciate any advice on how to fix this or troubleshoot further. Thank you

Hi there,

I'm sorry to hear that you're not able to call your son on your Sonic home phone! It's possible that there is a routing issue on our end with our upstream provider. I would recommend trying to call your son ~5 times, then contact our support team at (855) 394-0100 to report the issue. We can send those fresh call failure examples to our Network Operations team to investigate and/or report to our upstream carrier to resolve the issue.

Kind regards,
Brandon C.
Customer Support
