I need a tier 2 specialist
Device Info: * Model: Samsung Galaxy S22 Ultra (BYOD from AT&T)
- Software Version: CCT/CCT,CCT/ATT (Confirmed Xfinity Firmware)
- Activation Method: eSIM
The Current Problem:
The phone is experiencing a "No Service" state characterized by a circle with a diagonal line. Most importantly, since the last Xfinity store visit, the phone intermittently shows 1 bar of service for a few seconds before immediately dropping back to "No Service."
Troubleshooting Already Completed:
- Store Visit: A representative "refreshed" the connection. It worked for a few minutes in the store but failed immediately after leaving.
- Network Reset: Performed "Reset Network Settings" with no permanent change.
- Manual Network Scan: The hardware successfully "sees" Xfinity/Verizon towers in a manual scan, confirming the antenna is functional.
- Software Check: Confirmed the device has transitioned to the CCT (Xfinity) carrier code; it is not stuck on AT&T firmware.
Technical Diagnosis for Tier 2:
The intermittent "1-bar" signal suggests the phone is successfully performing a "blind" handshake with the tower, but the eSIM profile is being rejected by the Xfinity authentication server during the registration phase. This is common with BYOD S22 models where the IMEI 2 (eSIM slot) is not correctly mapped in the billing system.
