Only been traveling in larger cities here in South America but never had a problem. Hotspots are everywhere and if you live somewhat central most hotels have internet too.
That aside, down here it's popular with mobile internet, if you have a cellphone that supports it you can buy prepaid cards to get online, it's not that expensive.
Operators like Claro, Tigo, CTI etc I believe all has some form of it.
