Almost everyone has experienced a sudden disconnection or termination of calls when talking to someone on a phone. Commonly known as call drops, they often happen in areas with little to no connectivity, but sometimes you might also experience them when at home or the office. While there are several reasons behind call drops, here are some of the most common reasons behind call drops. Weak signal One of the most common reasons why you might be experiencing call drops is because of weak or fluctuating signals. While you can quickly check the strength of your network by checking how many bars the network has from your iPhone's or Android phone's status bar, no industry standard ties cell signal strength to the number of bars. This means one bar for Airtel may be the same as three for Jio. Software glitches While this is not a frequent occurrence, sometimes software updates may impact network connectivity. Google's Pixel series phones often have had the very same problem, with many users saying that their phone was unable to connect to the network after some software updates. Network congestion If you live in a densely populated area, high network traffic might also be a reason behind call drops. This usually happens when many users in an area who are connected to the same tower try to access the network simultaneously. How to prevent call drops? While there is no surefire method to prevent call drops, here are some tips and tricks that can help address the issue. Switch to a different network If you are not getting a good signal at your home or office, switching to a different network provider might help. But before you do, make sure you check all the plans and ask others how the telecom operator's network is in the area you live or work. Some telecom providers like Airtel also have a map where you can check network availability. Update your phone Updating your phone to the latest version can also help fix network issues. If you are experiencing frequent call drops, check for software updates and make sure your phone is on the latest software version. Restart your phone This may not sound intuitive, but sometimes all you need is a simple restart to fix your network problems. While Android and iOS devices can easily connect to the best network available, if nothing helps, restarting your phone can help fix connectivity issues. Disable Wi-Fi calling If you are in an area with low to no network connectivity, your smartphone switches to call over Wi-Fi. While this feature can come in handy, sometimes it is also the reason why your phone might be dropping calls. Wi-Fi calling is enabled by default on most Android phones, but you can disable it by turning off the 'Use Wi-Fi calling' toggle from the SIM settings in the 'Settings' app. On iPhone, this option can be found under the 'Phone' section in the 'Settings' app. Reset network settings As a last resort, you can also try resetting your network settings to fix frequent issues with calls. Depending on your smartphone model, this option might be located under different sections, but you can quickly find it by searching for the term 'reset' in the settings app. One thing to keep in mind is that this option might also erase your saved Bluetooth and Wi-Fi devices.
