While enabling wi-fi calling can be useful, basically, you’re just enabling your android or iOS device to function as a VOIP (Voice Over Internet Protocol) device. This is useful when you have internet, but not cell service, but it won’t work when both cell service and the internet are down.

Copper-wire landline service will still work in those cases, but that service is being phased out by phone companies, as they are also moving to VOIP services.

Another option is to employ some sort of two-way radio system to reach those close to you, but there are too many variables involved to get into those options here. Some of the radio options to consider are CB, Ham (amateur), FRS, and GMRS.
