1 What is VoLTE?

VoLTE stands for Voice over LTE, which means that your voice calls are transmitted over the 4G LTE network instead of the traditional 2G or 3G networks. This allows for higher quality, faster, and more reliable voice calls, as well as the ability to use data services while on a call. VoLTE also supports HD voice, which enhances the clarity and richness of your conversations.

2 What is IMS?

IMS stands for IP Multimedia Subsystem, which is a framework that enables the integration of various multimedia services over IP networks, such as voice, video, messaging, and conferencing. IMS enables VoLTE, as well as other features such as Wi-Fi calling, RCS (Rich Communication Services), and VoWiFi (Voice over Wi-Fi). IMS also allows for interoperability between different devices and networks, as well as seamless handovers between different access technologies.

3 How to check if your device and carrier support VoLTE and IMS?

Not all devices and carriers support VoLTE and IMS, so you need to check if yours do before you can enable them. To check if your device supports VoLTE and IMS, go to Settings > About Phone > Status > SIM Status and look for VoLTE and IMS Registration. If they are available, you will see them listed under your network status. To check if your carrier supports VoLTE and IMS, you can visit their website or contact their customer service and ask them if they offer these services and what are the requirements and fees.

4 How to enable VoLTE and IMS on your Android device?

If your device and carrier support VoLTE and IMS, you can enable them in your settings. To enable VoLTE, go to Settings > Network & Internet > Mobile Network and toggle on VoLTE or Enhanced 4G LTE Mode. To enable IMS, go to Settings > Network & Internet > Advanced > IMS Settings and toggle on the IMS services you want to use, such as Wi-Fi calling, RCS, or VoWiFi. You may need to restart your device for the changes to take effect.

5 What are the benefits of using VoLTE and IMS?

VoLTE and IMS can offer a range of advantages, such as improved voice quality and reliability, with HD voice and reduced background noise, latency, and dropped calls. Furthermore, enhanced multimedia features are enabled, such as video calls, rich messages, and file sharing with compatible devices and networks. Additionally, battery consumption is reduced due to not needing to switch between radio frequencies. Finally, network efficiency is increased because more data and voice traffic can be handled with less bandwidth.

VoLTE improves the spectral efficiency and reduces network costs. The spectral efficiency on LTE networks is far higher than that on traditional GSM/UMTS networks. Provided with the same bandwidth, an LTE cell has a voice capacity more than 100% larger than a UMTS cell. VoLTE improves user experience. VoLTE uses high-definition broadband AMR voices, which deliver a better auditory experience than narrowband AMR voices commonly used by GSM/UMTS networks. The mean opinion score (MOS) for broadband AMR voices at a peak rate of 23.85 kbit/s is 1 higher than the MOS for narrowband AMR voices at a peak rate of 12.2 kbit/s. In addition, tests show that the call setup delay for VoLTE is reduced by more than 2/3 compared with the delay on 2G/3G .

6 What are the challenges of using VoLTE and IMS?

Using VoLTE and IMS can also pose some challenges, such as limited coverage and compatibility in all areas or on all devices and carriers, which may result in a fallback to 2G or 3G networks when traveling or roaming. Additionally, VoLTE and IMS can use more data than 2G or 3G networks, particularly for video calls and multimedia messages, so it's important to monitor your data usage. Furthermore, VoLTE and IMS can expose your data and voice traffic to cyberattacks due to the use of IP networks that may not be encrypted or protected. Therefore, you may need to use VPNs or other security measures to protect your privacy and data.

UE compatibility problems may occur at the initial phase of VoLTE service deployment. VoLTE performance in terms of capacity, coverage, UE power saving, and mobility management based on the basic VoLTE services. Some features require UE support. UE compatibility test must be performed before you enable related features.
