I recently made an overseas trip where I made use of Wireless calling and it worked great for me there and I configured my phone to prefer it over roaming if Wireless was available which was a great option. Now that I'm home I would like to do the same thing because my Verizon Wireless coverage is very poor here at the house, barely usable. However I don't see any way to configure my phone to do the same thing where it will use the wireless over the cellular network if the wireless is available. What am I missing? Right now it continues to try to use the cellular network which again is barely usable at best.
