Why Yes 5G SIM Card Can't Make Calls: Device Without VoLTE | Learn More

Introduction to 5G SIM Cards and VoLTE

The introduction of 5G technology has brought a revolution in mobile communication, offering faster speeds and better connectivity. However, white they able access to internet ,some users face an issue where their 5G SIM card cannot make outgoing call, incoming calls and even SMS . The main reason behind this is the lack of VoLTE support in their device. VoLTE, or Voice over LTE, is essential for making voice calls over the LTE network(4G), which is a crucial aspect of 5G technology. Without VoLTE, even the most advanced 5G SIM card cannot function properly for voice calls, leaving users frustrated and confused. This blog post will explain why VoLTE is necessary for calls if you are using YES prepaid or postpaid plan , the common devices that lack this support, and possible solutions to overcome these issues.

If you are using a Yes (Malaysia) SIM card, (Yes | First to 5G)​​ ​you will need a device that supports VoLTE (Voice over LTE) to make calls. Yes operates on a fully 4G LTE network, which means traditional voice calls (which rely on 2G or 3G networks) are not supported. Without VoLTE, the Yes SIM card can only use data services, and voice calls will not be possible​ .Please check out these Yes Supported Devices it is a officail list of devices compatible with Yes 4G LTE and 5G networks, indicating the necessity of VoLTE support for making calls.

Understanding VoLTE Technology

VoLTE stands for Voice over Long-Term Evolution. It is a standard for high-speed wireless communication that allows voice calls to be made over the LTE network rather than older 2G or 3G networks. The primary advantage of VoLTE is the enhanced call quality, with clearer and more reliable connections. Additionally, VoLTE enables simultaneous use of voice and data services, which is not possible with traditional networks. The technology works by converting voice into packets of data, which are then transmitted over the LTE network. This process ensures that voice calls benefit from the high speed and low latency characteristics of LTE, leading to a superior calling experience.

Why 5G SIM Cards Can't Make Calls Without VoLTE

The inability of a 5G SIM card to make calls without VoLTE is rooted in the technological requirements of the network. 5G, by its very nature, is designed to operate over high-speed data connections. For voice services to function on a 5G network, VoLTE is required to handle the voice data. Without VoLTE, the device cannot utilize the LTE network for voice calls, defaulting to older networks like 2G or 3G, which may not be available or supported by the SIM card. This lack of compatibility results in failed call attempts or the inability to connect calls altogether. As mobile networks continue to evolve, ensuring VoLTE support in devices becomes crucial for maintaining seamless communication.

Common Devices Without VoLTE Support

Several older smartphone models and some budget devices do not support VoLTE. These devices were designed before the widespread adoption of VoLTE technology or aimed at cost-sensitive markets where advanced features were not prioritized. Examples of such devices include some early 4G smartphones and certain entry-level models from various manufacturers. Users of these devices often experience issues when trying to make voice calls with a 5G SIM card, as their phones cannot access the required VoLTE technology. As a result, these users might face connectivity problems or be unable to place calls entirely on 5G networks.

Solutions for 5G SIM Card Call Issues

If you are experiencing call issues with your 5G SIM card due to a lack of VoLTE support, there are a few solutions to consider. Firstly, check if your device supports VoLTE by consulting the user manual or the manufacturer's website. If it does, ensure that VoLTE is enabled in the device settings. If your device does not support VoLTE, you may need to upgrade to a newer model that includes this feature. Additionally, contacting your mobile carrier for assistance can help, as they may offer firmware updates or other solutions to enable VoLTE on your device. Using a dedicated VoLTE-enabled device ensures that you can make the most of your 5G SIM card's capabilities.

Future of VoLTE and 5G Integration

The future of mobile communication lies in the seamless integration of VoLTE and 5G technology. As 5G networks continue to expand globally, VoLTE will become an essential feature for all smartphones. Manufacturers are increasingly incorporating VoLTE support into new devices to ensure compatibility with advanced networks. Additionally, ongoing advancements in technology will likely lead to even better voice quality and more reliable connections. As VoLTE and 5G become ubiquitous, users can expect a more integrated and efficient mobile communication experience, with uninterrupted voice and data services across all devices.

By understanding the importance of VoLTE for making calls with a 5G SIM card, users can better navigate the challenges and solutions associated with this technology. Ensuring that your device supports VoLTE is key to enjoying the full benefits of 5G connectivity, including high-quality voice calls and reliable data services.
