Interference during phone calls

When I try to call someone, they hear a very loud interference. This seems to happen when I’m connected to wifi, if I disconnect and restart my phone the issue doesn’t seem to appear again, but I’m not sure. This problem appears only during normal calls, every other use of the microphone is normal.

P.s. I don’t have the wifi calling setting.

If either of you are using Bluetooth while making calls then...


Bluetooth interference can potentially cause interference due to the disruption of the wireless communication between devices. Bluetooth operates in the 2.4 GHz frequency range, which is also used by various other devices such as Wi-Fi routers, microwaves, cordless phones, and even some baby monitors. When multiple devices are operating in close proximity and using the same frequency band, interference can occur.


Here's how Bluetooth interference can impact Voice:


  1. Audio Streaming Interruptions: When you're streaming music via Apple Music or using Siri to play audio content, Bluetooth interference can disrupt the connection between your device (such as an iPhone) and the Bluetooth speaker or headphones. This interference can result in the audio stuttering, dropping out momentarily, or experiencing poor sound quality.
  2. Bluetooth devices transmit data in packets. Interference can cause some of these packets to be lost or corrupted during transmission. As a result, the receiving device may have trouble decoding the audio correctly, leading to weird sounds.
  3. Bluetooth uses different channels within the 2.4 GHz frequency range to establish connections. When there are many Bluetooth devices in close proximity, multiple connections can create congestion on the available channels. This congestion can cause interference, leading to degraded performance for Apple Music streaming or Siri interactions.


To mitigate Bluetooth interference issues and reduce stuttering:


  1. Minimize the number of active Bluetooth devices in close proximity to each other. Switch off or move away devices that are not in use or causing interference.
  2. Increase the distance between your Bluetooth devices (e.g., your iPhone and Bluetooth speaker/headphones) to reduce the impact of interference.
  3. If your Wi-Fi router supports it, consider using the 5 GHz frequency band for Wi-Fi connections instead of 2.4 GHz. This can reduce potential interference between Bluetooth and Wi-Fi signals.



By implementing these steps, you can help minimize Bluetooth interference and improve the overall performance of Siri's voice.

What Call? On an iPhone, you can make and receive various types of calls. Here are the different types:


  1. These are standard voice calls made over the cellular network. They utilize your carrier's voice network to connect you with other phone numbers. Allow phone calls on your iPad, iPod touch, and Mac
  2. FaceTime Audio allows you to make voice calls over Wi-Fi or cellular data using your internet connection. It provides higher audio quality compared to traditional cellular calls.
  3. FaceTime Video enables you to have video calls with other FaceTime users. It uses the front or rear camera on your iPhone to transmit live video during the call. Use FaceTime with your iPhone or iPad - Apple Support (IN)
  4. VoIP (Voice over Internet Protocol) calls use internet connectivity to make phone calls. Apps like Skype, WhatsApp, Viber, and Google Hangouts utilize this technology, allowing you to make voice and video calls over the Internet.
  5. Some carriers support Wi-Fi calling, which allows you to make and receive calls over a Wi-Fi network instead of relying solely on cellular coverage. This can be useful in areas with weak cellular reception. Make a call with Wi-Fi Calling - Apple Support (IN)
  6. The App Store offers numerous calling apps that utilize different technologies. These apps can provide additional features and options for making calls, such as international calling, call recording, and more.


It's important to note that the availability of certain call types may depend on your iPhone model, iOS version, and carrier.
