Enabling Advanced Calling on your iPhone 15 Plus can enhance your calling experience by providing you with high-definition voice quality and the ability to make calls over Wi-Fi. To do this, you’ll need to dive into your phone settings and make a few adjustments. After following the steps below, you’ll be all set to enjoy clearer and more reliable calls on your iPhone 15 Plus.

Step by Step Tutorial: Enabling Advanced Calling on iPhone 15 Plus

Before jumping into the steps, it’s important to know that Advanced Calling, also known as Voice over LTE (VoLTE) or Wi-Fi Calling, allows you to make and receive calls using a high-speed internet connection. This can greatly improve call quality and is especially useful in areas with poor cellular reception.

Step 1: Go to Settings

Access the Settings app on your iPhone 15 Plus by tapping the gear icon on your home screen or app library.

Once you’re in Settings, you’ll see a list of options to choose from. This is where you’ll be able to tweak your phone’s functionality, including enabling Advanced Calling features.

Step 2: Tap on ‘Cellular’

Scroll down and tap on the ‘Cellular’ option which will take you to your phone’s cellular settings.

In the Cellular settings, you can manage all options related to your phone’s connection to the cellular network, including data usage and network selection.

Step 3: Select ‘Cellular Data Options’

Within the Cellular settings, find and select ‘Cellular Data Options’ to access more specific data settings.

This is where you can turn on or off your cellular data, as well as enable options like LTE and roaming.

Step 4: Enable ‘Voice & Data’

Look for the ‘Voice & Data’ option and enable it by tapping on it and selecting ‘LTE, VoLTE On’ or ‘Wi-Fi Calling’ based on your preference.

By enabling ‘LTE, VoLTE On,’ your calls will be made over the LTE network, providing higher quality audio. If you choose ‘Wi-Fi Calling,’ your calls will use a Wi-Fi network when available, which is ideal for locations with weak cellular signals.

Once you’ve completed these steps, your iPhone 15 Plus will now use Advanced Calling features when you make or receive calls. You should notice a significant improvement in call quality, and if you’re using Wi-Fi calling, you may also see better battery life since your phone won’t be constantly searching for a cellular signal.

Tips for Enabling Advanced Calling on iPhone 15 Plus

  • If you’re traveling internationally, check if your carrier allows the use of Wi-Fi Calling abroad to avoid roaming charges.
  • Keep your iPhone’s software updated, as updates can include improvements to Advanced Calling features.
  • If you experience any issues with Advanced Calling, try toggling the feature off and on again in the settings.
