What are the reasons why the internet does not work while talking on the phone

In today’s modern world, we heavily rely on the internet for various activities, such as browsing, streaming, and communication. However, there are instances when our internet connection might fail or become noticeably slower while we are on a phone call. This inconvenience often leaves us wondering about the reasons behind this issue. Let’s explore some possible explanations for why the internet does not work while talking on the phone.

One significant factor that can affect your internet connection during a call is your phone’s technology. Older phone systems, such as 2G or 3G, use a circuit-switched network that prioritizes voice calls over data transmission. This means that during an ongoing call, the phone allocates most of its network resources to maintain the call quality and stability. Consequently, your internet connection is given less bandwidth, resulting in slower or interrupted internet browsing.

Another reason why your internet may falter during a phone call pertains to signal interference. Mobile networks, particularly those using frequency-division duplexing (FDD) technologies, operate on different frequency bands for transmitting and receiving data. However, cell phones, both for calls and internet, utilize a similar frequency range. This overlap can lead to interference between the phone’s cellular radio and its Wi-Fi or data connectivity, causing a reduction in internet performance.

Additionally, the issue may lie in your service provider’s infrastructure. Some mobile data networks might not be optimized to handle simultaneous voice and data transmission efficiently. This limitation is more common in older or less developed networks, as they often have lower capacity and less advanced technologies. In such cases, the network’s inability to handle concurrent voice and data traffic might restrict your internet access during phone calls.

Furthermore, the limitations of your phone itself can contribute to internet connection issues during calls. If your device lacks the necessary hardware capabilities to handle simultaneous voice and data transmission, it might automatically divert all network resources to prioritize the ongoing call. This can lead to a temporary disruption or degradation of your internet connectivity until the call ends.

Lastly, the wireless environment around you can impact your internet connection during phone conversations. If you are in an area with poor network coverage, your device will struggle to maintain a stable signal for both phone calls and internet usage. Factors such as distance from the nearest cell tower, physical obstructions, or network congestion can all contribute to weaker signals, resulting in a compromised internet experience during calls.

Overall, several factors can explain why the internet might not work as expected while talking on the phone. Older phone technologies, signal interference, limitations of service providers’ infrastructure, hardware constraints of phones, and unfavorable wireless environments are some possible reasons for this issue. Understanding these factors can help you better manage your expectations and troubleshoot connectivity problems effectively. If you frequently encounter this problem, contacting your service provider or considering a phone upgrade could potentially improve your overall experience.
