Calls nor SMS can be sent from eSIM while in roaming if lockdown mode is activated
I reported it to Apple twice, they are aware of a bug, but it still wasn’t fixed after 3 months. eSIM does not work properly while in roaming if lockdown mode is enabled. No calls can be made, nor SMS can be sent.
After lockdown mode is deactivated, eSIM works properly again (while still in roaming).
