Echo issues on my iPhone 15 Pro Max when using speakerphone

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.

Please contact your Carrier. This is not an iPhone settings issue.

• Sometimes, weak signal or network congestion can cause audio to be routed back to you, creating an echo effect.
• Carrier settings updates can sometimes improve call quality. To check for carrier updates, go to Settings > General > About. If an update is available, you'll be prompted to install it.
• Ensure there are no physical obstructions around the microphone or speaker areas of your iPhone, such as a case or debris.
• During a call, try toggling between the speakerphone and regular phone mode. Additionally, check if the issue persists when using headphones or a Bluetooth headset.
