I managed to restore network connectivity on my Pixel 11 after encountering the registration errors mentioned in this thread. I applied several configuration changes simultaneously, so it is unclear which specific setting resolved the issue:
- Disabled Adaptive Battery and Smart Charging
- Changed System Language to English (United States) (previously set to English (France))
- Reset Private DNS to Automatic
- Disabled Caller ID & Spam in the Phone app settings
Tried the demo, it works!
