FaceTime activation error on iPhone 13

Hello everyone,

I recently bought an iPhone 13, and I’ve been facing a problem with FaceTime activation. Every time I try to enable FaceTime in the settings, I get an error message saying that the activation cannot be completed.

I already tried different methods:

restarting the device,

checking my internet connection,

signing out and signing back into my Apple ID,

even attempting to create a new Apple ID.

But none of these solutions worked. FaceTime still shows an activation error.

Has anyone experienced something similar? Maybe there is a known solution or a way to contact Apple directly to fix this issue?

Thanks in advance for any advice.
