If you lose a WAZE "signal" that means you lost the GPS satellites and nothing at all will work in that location. WAZE and others as I am sure you know use the GPS chip in your phone to get GPS satellite signals. Now if you lose CELLULAR service you will lose the map but still have voice commands and if you cache the maps they will always be on your phone with or without CELL signal. It's very rare to lose GPS signal since it is from satellites unless you are in a tunnel. With WAZE, GOOGLE and APPLE if you set your route
while at home in WIFI range it will download the map for you and even if you lose cellular service you will never know it. For local trips it's not a big deal but for long trips you will never lose maps and directions since the GPS sats are rarely out of range. WIth GOOGLE MAPS you can pre-download large areas in advance and also never lose your maps even if you lose cell signal. I have Sumter & parts of Marion and Lake pre-downloaded in Google Maps to my phone and Google constantly updates it. That's one of the reasons why there a so few stand-alone automobile GPS devices these days VS. a number of years ago. Many reviews have shown that the NAV APPS are as good and often with many more features than free standing automobile GPS devices.
For those interested in caching (downloading) maps for use if you lose cellular service:

Caching Maps using Apple Maps:

This will save the maps on your phone so you don't have to reply on cellualr service but of course you must have GPS service which probably covers 95% of the earth.
