I am having the same issue. Can Verizon Customer Support assist?
I have an unlocked moto x4 that does not have a setting for wifi calling, yet Motorola says is capable of wifi calling. on the hidden menu there is a setting for it, but it is grayed out and I cannot turn it on. Any suggestions?
We would be happy to help with any questions you have regarding your Moto x4. Is this a Verizon Wireless branded device, or a phone that was intended to work with a different carrier?
