I hope that the cellular infrastructure in Cairo is good enough to make Uber useful. I had a lot of problems staying connected when I was in Mexico City, such that I consistently had problems meeting up with drivers. And my cell reception in CDMX was pretty good in comparison to some other places I've been (see: most of Canada).
I was just in Rome and Google Fi was spotty at times.
Except maybe for going out to dinner, it would be foolish not to use a private guide and driver in Cairo for two days of sightseeing. The Antiquities Museum at Tahrir Square is overwhelming without a guide.
