I receive very poor reception in my home that ranges from one bar to (sometimes) two. It cuts out and drops calls frequently. It seems as though my phone (iPhone 7 running iOS 11.2.5) is defaulting to the poor cellular connection instead of my WiFi. It's driving me nuts, especially as I use the line for work calls and they keep getting dropped. Does anyone know how to make the WiFi the default connection? I put the phone in airplane mode and toggled the wifi on and off and got it to work that way, but that doesn't solve the problem for incoming calls, and I don't want to have to remember to put my phone in airplane mode whenever I arrive to my house, and then turn it off again when I leave.
I've google this and seen others with the same frustration - some of which have simply had to leave the carrier, which I do not want to do.
Thank you for your help!

Thanks for clarifying. I think in this situation we will more than likely need to look into a device replacement. There is no reason the device should be trying to connect to cellular with when you are connected to Wi-Fi and have Wi-Fi calling enabled. I know that you said it works fine on Wi-Fi when you have Airplane mode on and Wi-Fi on but still, the phone should not switch to cellular when you are connected to Wi-Fi calling unless your phone is losing connection to Wi-Fi for some reason.
