   I would tend to agree with you that the coverage at your home might not   
   matter _inside_ the house when you set up the phone for free Wi-Fi calling.   
      
   For example, this screenshot taken just now shows a graph of what appears to   
   be excellent cellular signal strength over time of -90 to -60dBm (RSRP).   
       
      
   If you don't know it, that's damn good signal strength for cellular signal.   
   But the unique cell id tells me it's actually using the in-home cell tower.   
      
   When I unplug the internal cell towers inside my house, the cellular signal   
   strength immediately drops to a (still respectable) -100 to -90 dBm (RSRP).   
       
      
   All that matters is how close you are to your router when you use the phone   
   for calling - but - I don't know (nospam might know better than I do?) if   
   Wi-Fi calling has anything to do with cellular data. I suspect not.   
      
   Therefore, if there's no nearby tower, then I think you'd _still_ need a   
   cellular tower inside your home in order to get cellular data you pay for.   
      
   That free cellular tower would most likely be connected to your router, but   
   if you have "some" cellular signal, a free cellular repeater would work as   
   well I would think.    
      
   I have all three, but I also have signal outside my house as shown by this   
   screenshot I took a few minutes ago showing 4G inside & 5G on my balcony.   
       
      
   If my eyes were better, I'd be able to discern the two little up/down arrows   
   indicating when the cellular appears to be working - but those icons are   
   just too small to see until they're blown up on my large computer monitor.
