The advent of 4G LTE networks has revolutionized the way we communicate, offering faster data speeds and clearer voice calls through Voice over LTE (VoLTE). However, many users encounter a frustrating issue where their phone does not show VoLTE, hindering their ability to make high-quality voice calls and access other advanced features. In this article, we will delve into the possible reasons behind this issue and provide a step-by-step guide on how to resolve it.
Understanding VoLTE and Its Requirements
VoLTE is a technology that enables voice calls to be made over the 4G LTE network, providing superior call quality and faster call setup times compared to traditional 2G and 3G networks. To use VoLTE, your phone must meet certain requirements, including support for LTE Band 4 or other compatible bands, a compatible operating system, and activation of the VoLTE service by your carrier. Additionally, your phone’s hardware and software must be optimized to handle VoLTE calls.
Hardware and Software Requirements
To support VoLTE, your phone must have a compatible processor and radio frequency (RF) hardware. The processor must be capable of handling the complex signal processing required for VoLTE, while the RF hardware must be able to transmit and receive signals on the supported LTE bands. Furthermore, your phone’s operating system must be optimized for VoLTE, with the necessary software components and drivers to enable VoLTE calls.
Carrier and Network Requirements
In addition to the phone’s hardware and software requirements, your carrier and network must also support VoLTE. This includes activation of the VoLTE service on your account, as well as availability of VoLTE coverage in your area. If your carrier does not support VoLTE or if the service is not activated on your account, you will not be able to use VoLTE on your phone.
Troubleshooting Steps to Resolve the VoLTE Issue
If your phone is not showing VoLTE, there are several troubleshooting steps you can take to resolve the issue. These steps include:
Checking your phone’s settings to ensure that VoLTE is enabled, verifying that your carrier supports VoLTE and that the service is activated on your account, and checking for any software updates that may be required to enable VoLTE. You can also try resetting your phone’s network settings or performing a factory reset to resolve any software-related issues.
Checking Phone Settings and Carrier Support
The first step in troubleshooting the VoLTE issue is to check your phone’s settings to ensure that VoLTE is enabled. This can usually be done by going to the Settings app, selecting Mobile networks or Cellular networks, and looking for the VoLTE or Enhanced 4G LTE Mode option. If this option is not available, it may indicate that your phone does not support VoLTE or that the service is not activated on your account.
Checking for Software Updates
Another possible cause of the VoLTE issue is outdated software. To check for software updates, go to the Settings app, select System or System update, and follow the prompts to download and install any available updates. It is essential to keep your phone’s software up to date, as updates often include bug fixes and performance improvements that can resolve issues like the VoLTE problem.
Advanced Troubleshooting Steps
If the basic troubleshooting steps do not resolve the VoLTE issue, there are several advanced steps you can take to further diagnose and resolve the problem. These steps include checking the phone’s IMEI number to ensure that it is compatible with your carrier’s network, using a different SIM card to rule out any issues with the current SIM, and contacting your carrier’s technical support for further assistance.
Checking the Phone’s IMEI Number
The IMEI number is a unique identifier assigned to each mobile phone, and it can be used to check if the phone is compatible with your carrier’s network. To check the IMEI number, dial *#06# on your phone and note down the 15-digit number that appears on the screen. You can then check the IMEI number on your carrier’s website or contact their technical support to verify that the phone is compatible with their network.
Using a Different SIM Card
If you suspect that the issue is related to the SIM card, you can try using a different SIM card to rule out any problems with the current SIM. This can be done by obtaining a new SIM card from your carrier and inserting it into your phone. If the VoLTE issue persists with the new SIM card, it may indicate a problem with the phone’s hardware or software.
Conclusion
In conclusion, the VoLTE issue can be caused by a variety of factors, including hardware and software limitations, carrier and network issues, and configuration problems. By following the troubleshooting steps outlined in this article, you can diagnose and resolve the VoLTE issue on your phone. Remember to always check your phone’s settings and carrier support before attempting any advanced troubleshooting steps, and do not hesitate to contact your carrier’s technical support if you need further assistance.

What is VoLTE and how does it work?
VoLTE, or Voice over LTE, is a technology that allows users to make voice calls over a 4G LTE network. This is different from traditional voice calls, which are made over a 2G or 3G network. VoLTE provides several benefits, including higher quality voice calls, faster call setup times, and the ability to use data and voice services simultaneously. To use VoLTE, your phone must be compatible with the technology and your carrier must support it.
In order for VoLTE to work, your phone must have the necessary hardware and software to support it. This includes a compatible LTE chipset and a VoLTE-enabled operating system. Your carrier must also have a VoLTE network in place, which involves upgrading their infrastructure to support the technology. Once these conditions are met, you can enable VoLTE on your phone and start making voice calls over the LTE network. It’s worth noting that not all carriers support VoLTE, so it’s a good idea to check with your carrier to see if they offer the service.
Why is my phone not showing VoLTE?
There are several reasons why your phone may not be showing VoLTE. One common reason is that your phone is not compatible with the technology. This could be because your phone is an older model that does not have the necessary hardware or software to support VoLTE. Another reason could be that your carrier does not support VoLTE, or that they have not enabled it on your account. You may also need to enable VoLTE manually on your phone, as it is not always enabled by default.
To resolve the issue, you can try checking your phone’s settings to see if VoLTE is enabled. You can also contact your carrier to see if they support VoLTE and if it is enabled on your account.
