I Ubered all over Lima for 3 days. No issues at all - cars always clean, drivers always friendly. I was impressed: the cars were always compact Kias and such, but definitely nicer than the typical taxi.

I had no problem getting cell service throughout Lima using my U.S. multiband device...it was just slow. It was sufficient to get the Uber requested and confirmed, but viewing real-time maps and such didn't really work.

As for safety, there were at least a dozen times where I was certain we were about to get T-boned in the middle of an intersection. But of course it never happened...somewhat these drivers manage to navigate their way around town without killing each other, which hardly seems possible.

Funny thing is that United was sending me emails with Hertz offers for Lima: I don't see how a foreigner could possibly drive here. You'd have to be from Cairo or Delhi to find this traffic mellow.
