What happens to my 4G connection when I’m on a call?
When you’re on a call, your phone is using a technology called Circuit Switched (CS) to connect to the cellular network. This technology is designed specifically for voice calls and is separate from the Packet Switched (PS) technology used for data transmission, such as 4G internet. As a result, when you’re on a call, your phone is essentially switching between two different modes: one for voice and one for data. This can sometimes cause issues with your 4G connection, especially if your phone is not capable of handling both modes simultaneously.
In areas with poor network coverage or congestion, the switch between CS and PS technologies can be more pronounced, leading to dropped connections or a loss of 4G signal. Additionally, some phones may not support a feature called Voice over LTE (VoLTE), which allows for simultaneous voice and data transmission over the 4G network. If your phone doesn’t support VoLTE, you may experience a drop in 4G signal strength or speed when you’re on a call. However, many modern smartphones do support VoLTE, and network providers are continually improving their infrastructure to minimize the impact of CS and PS switching on 4G connections.
Why do I lose 4G when on a call in areas with good coverage?
Even in areas with good network coverage, you may still experience a loss of 4G signal when you’re on a call. This can be due to various factors, such as network congestion, phone hardware limitations, or software issues. For example, if there are many users in the same area making calls or using data-intensive applications, the network may become congested, leading to a decrease in 4G signal strength. Additionally, some phones may have hardware limitations that prevent them from handling simultaneous voice and data transmission efficiently, even in areas with good coverage.
In some cases, the issue may be related to the phone’s software or firmware. For instance, a bug in the phone’s operating system or a misconfigured network setting can cause the phone to drop the 4G connection when a call is made or received.
