Google maps works okay on slow connections if you download the tiles for the city you're in beforehand (not that non-technical unemployed people should be expected to do that).
The worst thing is load balancers with a 10 or 20 second timeout, because there's almost nothing you can do other than use Opera Mini or something.

At that point, why would you use Google Maps at all? Osmand will do the same thing, and requires no connection.
