Hi, I been playing around with WiFi calling as I get little signal at home. I am on Oppo A9. When I put my phone on airplane mode the WiFi calling and texting works fine, I can be heard clearly.
However when I turn airplane mode off it seems that the WiFi calling doesn't come into play. I will usually have 1 bar of signal at home and when I get a phone call it always breaks up. I assume this is because it is using my poor network signal.
Is there something I can do so that the WiFi calling takes hold with low signal?

Thanks and Merry Christmas!
