Can satellite wifi support iPhone cell service?

If your internet is suitable for decent VOIP calls, it should be fine for carrier wifi calling. As KiltedTim mentioned though, satellite internet is notorious for not only latency, but dropping packets and other issues. There is a web site, VOIPreview.org (and a couple of others) that have online speed and QC tests you can run on your internet connection to see if it is likely to be an issue. In particular, your upload speed can be an issue with any wifi voice service, and high latency can make VOIP calls essentially impossible.

Your other option may be to use a home powered cell signal extender - those are not cheap and the installation is not trivial, but it may be your best bet - https://www.wilsonamplifiers.com/cell-phone-signal-booster-guide

Who is your carrier? If it's a larger carrier like AT&T or Verizon, you can get a device called a microcell which actually broadcasts a cell signal. You would need a wired broadband Internet connection though like Comcast, it wouldn't work with your current Satellite service, however if WiFi isn't working all that well from your Satellite service provider, maybe it's time to change anyway.

Does your carrier support wifi calling and is it setup on your iPhone (settings, phone, wifi calling ON)?

I am trying to improve my iPhone service in Prescott Valley AZ. I put in a satellite service thinking that it would help me get better phone connection while I am home. I have no trouble when I am on the road.

The satellite service isn't helping the phone at all. I have bluetooth and wifi on and it's set to pick up wifi when in this home.

Did you get a network extender from your carrier? Or, does your carrier support WiFi calling?

Even if your cellular carrier supports WiFi calling, the latency on Satellite based Internet service may be too poor to support decent calling.

The problem with that strategy is that it relies on a broadband Internet connection. If the latency of the connection is too high to support WiFi calling, the microcell is going to choke on it as well.
