Default to WiFi Instead of Cellular Connection (Not Working)




    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!
