How do I get wifi calling to be the default when at home?

[TIMSCH49]

I have a moto g6. I have a weak signal at home. I have wifi calling turned on and I have 'when roaming' set to 'prefer wifi'. From time to time, my phone shows it is using wifi calling. However, it appears my phone continues to prefer to use the weak or no cellular signal over wifi calling more often than not. I've read on other verizon community messaging threads for other phones that users turned on their airplane mode....or at least they said that worked for a while but stopped working.  When I turn on airplane mode and then turn on my wifi, I am unable to make a call and get a message that airplane mode must be turned off. I stand next to my wifi device and my wifi phone apps confirm I have a strong wifi signal. So, how do I get my wifi calling to override my weak to no cellular signal? Or, what other workarounds do people suggest?

TIMSCH49, I use WiFi calling all the time. I totally understand the importance of using this feature. I would be equally concerned if it was not working correctly. I am here to help and find out what is going on with your WiFi calling. You can find all the info on WiFi calling here: https://www.verizonwireless.com/support/wifi-calling-faqs/ What is the make and model of your phone? What is your zip code? Before the issues with WiFi calling, what changes were made to your device (software update, new/updated apps, etc...)?  SantoC_VZW
