Consumer Cellular equivalent to Verizon "Wireless Network Extender"

Is there a Consumer Cellular (ATT or T-Mobile) equivalent to the Verizon "Wireless Network Extender"?  That is a device that connects a Verizon subscriber's cell phone to the Internet via the subscriber's broadband Internet connection, so that the subscriber can make and receive phone calls in areas with no direct Verizon cell service.  I'm currently in an area where there is no T-Mobile or ATT service either, so my Consumer Cellular phone won't work.  (I'm supposed to be able to make and receive phone calls directly over the Internet using my CC smartphone, but that's not working either (!!!)... but that's a different question.)
