Can’t make phone calls. Only FaceTime.

FaceTime calls don't require cellular connectivity; instead, they can be conducted over the internet using Wi-Fi. This feature distinguishes them from traditional voice calls, which depend on cellular connectivity tied to the SIM card in use. FaceTime leverages the power of Wi-Fi, offering users the flexibility to engage in high-quality video calls without being tethered to cellular networks. This not only provides a more versatile and accessible communication option but also highlights the evolving landscape of telecommunications, where internet-based services play a pivotal role in enhancing connectivity.

FaceTime calls and regular voice calls (such as those made through traditional cellular networks or Voice over Internet Protocol (VoIP) services) serve the fundamental purpose of enabling communication between individuals. However, there are several key differences between FaceTime calls and regular voice calls:

1. FaceTime:
   1. FaceTime calls are made over the internet using Apple's proprietary FaceTime technology. They typically require a Wi-Fi or cellular data connection.
   2. FaceTime is exclusive to Apple devices such as iPhone, iPad, iPod Touch, and Mac. It is not available on non-Apple devices.
   3. FaceTime often provides additional features beyond basic voice calling, such as video calling, Animoji/Memoji support, and the ability to switch between the front and rear cameras during a call.
   4. FaceTime calls are generally free when using a Wi-Fi connection. If using cellular data, it may consume data according to your data plan.
   5. Limited to Apple devices, which may restrict accessibility for users on different platforms.
2. Regular Voice Calls
   1. Regular voice calls can be made over traditional cellular networks (2G, 3G, 4G, 5G) or through VoIP services that utilize the internet, such as WhatsApp calls, Skype, or traditional landline calls.
   2. Regular voice calls can be made between devices regardless of the manufacturer or platform, as long as they support the same cellular network or VoIP service.
   3. Traditional voice calls may lack some of the advanced features found in FaceTime, primarily focusing on basic voice communication. However, VoIP services may offer additional features similar to or surpassing FaceTime.
   4. The cost of regular voice calls depends on your mobile carrier's plan and any applicable charges for international or long-distance calls.
   5. More universally accessible as they can be made between a wider range of devices and platforms.

Ultimately, the choice between FaceTime calls and regular voice calls depends on the devices and preferences of the individuals involved in the communication.
