I'm on Verizon and I want a Pixel 4a 5G, but having a difficult time paying the extra 100 for the Verizon version considering that I don't care about 5G. Can I grab an unlocked version and flash the Verizon firmware? I'd like to have WiFi Calling and the only way to get it is to have Verizon's firmware. Now, I know I could do this with a Pixel 5, but my understanding is that the Verizon 4a 5G has a different antenna. I went and looked at both at the Verizon store yesterday thinking that I wanted a Pixel 5, but just felt a little too small for my liking. Thanks!!!
