I just got a new Samsung Galaxy Note 10+ last night and I have a notification that is asking me to activate my wifi calling (which I have used frequently in the past with my V20). Each time I try to enable the wifi calling I get an error message that says "Unable to activate wifi calling at this time. Please try again later." I have tried disabling and enabling advanced HD calling and then resetting my phone, my location is on, I have a very strong wifi connection. The notification and error message has been there since my new phone was activated and turned on at the certified retailer last night.
We can certainly assist you with your Wi-Fi Calling. You will need a strong connection to the Verizon tower in order to enable the Wi-Fi Calling setting. What happens when you dial #832 from your device?
I am having the same problem on the Galaxy S10 plus that I just purchased on June 12th. No matter what I do it will not enable Wi-Fi calling. I have call Verizon technical support and ensure that my account is provision for Wi-Fi calling. I have tried every Solution that's in this forum and so far nothing has worked.
