Settings to Check When iPhone Call Merge is Not Working

Creating a conference call, or adding people to one call by merging different calls, is a great tool for business and connecting with friends. 

iPhone allows you to merge multiple calls easily. Although this feature is usually reliable, some settings can interfere with call merging. 

Settings including Wi-Fi calling, VoLTE, and outdated carrier settings can prevent you from merging calls on your iPhone. There could also be issues with your SIM card or the number of people you have on the call. Checking these settings will help you to find the issue and fix it. 

Below, we’ll discuss how to check and fix all these settings.

Check Wi-Fi Calling 

If you’re having trouble merging calls, the first setting you should check is Wi-Fi calling. 

Wi-Fi calling uses both cellular data and your Wi-Fi network to create a stronger connection. 

Some people prefer Wi-Fi calling because it can help stabilize and improve the quality of calls. 

However, Wi-Fi calling can make conference calls unstable. Switching this feature off might allow you to merge calls more easily. 

You can do this by following the steps below: 

  • Open your iPhone’s Settings app.
  • Select “Phone.” 
  • Find “Wi-Fi Calling” and toggle it to the off position. 

After disabling Wi-Fi calling, try to merge your calls again. If it still doesn’t work, check the next setting. 

Check VoLTE

VoLTE does almost the same thing as Wi-Fi calling. It can help stabilize calls, but it can also interfere when you’re trying to merge calls.  

To deactivate VoLTE, follow these steps: 

  • Open your Settings app. 
  • Select “Cellular.” 
  • Select “Cellular Data Options.” 
  • Find “Voice and Data.” 
  • Select “LTE.” 
  • Switch “VoLTE” off.

Now, try merging your calls again. Still no luck? Move on to the next step. 

Check Your Carrier Settings

Many people know to update their iPhone’s software, but they don’t always realize that there are also carrier settings they can update. 

To ensure your iPhone carrier settings are up to date, follow the steps below: 

  • Open your iPhone’s settings.
  • Select “General.”
  • Press “About.”
  • If there are updates available for your carrier settings, your phone will show a prompt.
  • Update your settings if prompted. 

Once your carrier settings are up-to-date, try merging your call again. 

Check Your SIM Card

If you’ve adjusted all the settings above and still cannot merge your calls, check your SIM card.

Your SIM card could also be responsible for any connectivity issues you might be facing. 

Take your SIM card out of your iPhone and check it for damage. If it seems to be fine, replace it.

This process alone might be enough to fit the SIM more securely and get your phone working better. 

Adjust the Number of People on the Call

If all else fails, make sure you aren’t trying to add too many people to your call. 

You can only merge five calls on your iPhone at once. If the merge suddenly stops working, make sure you aren’t trying to talk to more than five other people at once.   

If you do want to add more calls, you will need to use another app meant for larger groups. Some of your options include:

  • Zoom
  • FaceTime
  • Skype

If you try to merge more than five voice calls at once, it will automatically fail.

How to Hold Conference Calls on iPhone

If you have never held a conference call, or merged calls on your iPhone, before, you may be wondering how exactly you can do so.

Follow the steps below to start merging calls:

  • Open the Phone app and dial your first participant.
  • After the person answers, look at the call screen and select “Add Call.”
  • Dial the next participant.
  • Connect to the person on the other end of the line.
  • On the call screen, tap “Merge Calls.” 

You can repeat this process up to five times.

In Conclusion

If you can’t get your iPhone’s call merging function to work, there are several settings you can adjust to fix the feature. 

Wi-Fi calling, VoLTE, and out-of-date carrier settings can create connection issues with call merging. Check each of these settings until you find the problem.
