I'm taking a quick trip to Buenos Aires and while I know I can buy a SIM card for my phone, what I am curious about is the options of renting a cheap voice only phone while I am there.
Various websites offer such services in Buenos Aires and promise to deliver to your hotel (thus saving the time/hassle of hunting down a SIM card), but none mention prices or give me much confidence in their quality.
So do these sites deliver on their promises? And how does the cost stack up against a pre-paid SIM?
