Depending on your use case - a MVNO that supports wifi calling + iMessage etc can help. It’s nice in rural areas where the signal is weak.

I'm not trying to spend $40/mo to use wifi calling and iMessage. I'd rather spend $80 and never ever have to think about it.

Agreed. I loved the concept of wifi calling when it was introduced, but it always sucks when I use it. It always manages to find all of the flaws in the network I'm using.

It's just not worth the hassle when I can rely on a cell network that specializes in real-time voice communication.

USMobile supports wifi calling.

I can confirm this.
