I have not been able to use the conference call feature on my Iphone X 256GB since I got it. Contacted Verizon and they told me there was nothing they can do it is a device issue. Contacted Apple and they directed me back to Verizon. I need to use this feature for work a lot and now my job is on the line. My phone number ending in 0388 is the one that I need help with. I know Verizon does not make phones but I pay them directly for this device $47 per month. I do not think a customer should pay for something they can not use someone needs to address this. This is ridiculous and customers should not have to go back and forth form manufacture to service provider to have this issue still not fixed. Never thought I would say this but Im starting to think Verizon is not the premier company they use to be
