I recently purchased a new iPhone 13 to replace my iPhone 11.
This is a company paid phone so the instructions to transfer the service to the 13 state to call a number (from the old 11) and to follow the prompts. I dialed the number and began the process but unfortunately the call dropped.
I redialed and received the "we are unable to authenticate the phone" message. Announcement 11, Switch 144-1.
The message also stated to try again and if I still had a problem to dial #8899. I tried again and the same message played. I dialed #8899 and received the same message again.
I tried calling support but received an automated message stating that they are available Monday-Friday. So, I figured I'd try here for some possible insight as to whether this is something I can resolve myself or if I'll just need to wait till Monday.
