Elon Musk has announced that he plans to stop using his phone number, signaling a shift towards relying solely on X for communication. This move is seen as a strategy to endorse new features on X, particularly audio and video calls, which were officially introduced last year. However, it also means that only subscribers to the premium version of X will have the privilege of calling Musk. While X offers "enhanced call privacy" settings, the encryption level is not as robust as other platforms like WhatsApp or FaceTime. Despite Musk's efforts to promote the feature, its popularity remains uncertain, and it's still not widely mentioned on X's help pages. Musk's plan to transform X into the "everything app" includes integrating various features, including financial services, into the platform.
