Dear Experts,

I used to be able to make conference call from my iPhone, and all of a sudden I cannot.  I have opened a ticket with my carrier (Verizon) and tried to troubleshoot, but they could not help.  My phone is iPhone X, with iOS version 11.4.1.

Please advise.

When you call somone and get an answer there should be a "Add Call"  on your Apple Display to Conference another party to the call.

All parties must have iPhones and iPhones have to be on ios12

while on a call, tap add a call
to dial a contact select a contact from the contact tab
to dial a number, dial a number from the keypad tab then tap call or tap the call icon

Dear Wes and Stacy, thank you for a quick response.  My problem is, Add Call button is not enabled even after the other party picks up.  I have tested another iPhone where I was able to add calls to another iPhone or regular desk phone.  I also put my SIM card into another iPhone to test, and it worked.  There is something about this particular iPhone that does not let me add a call.

If the Upgrade doesn't do it then do this, but first make sure you do a full back up by tether to your computer  using iTunes to back up the iphone.

Then on the iPhone,  Settings , General, On the next screen scroll to the very bottom, Press Reset.
1st Try Reset Network Settings if you still Don't have the "Add Call" then try Reset All Settings.
