Hmm thanks for the advice, it sounds like a catch 22, any idea what the "much higher rate" is? Lets say I want 250mb-500mb, what kinda cost would I be looking at if you were to ballpark it? I really only need it for whatsapp and googling stuff like sites to see or whatever. I could just carry a guidebook, I speak Spanish so there's no need to translate and I am able to live without cell phone/chat contact but I like having it.

2ndary topic then as a follow up, how widely available is wifi in Santiago? Especially in Centro/Plaza de Armas region? My AirBnB has wifi, but like does McDonalds? Starbucks? Those kind of places. Maybe that's good enough, I don't mind popping in and having a coffee/burger so that I can use the wifi and research whatever I want for 20-30 minutes but I just prefer doing it on the go.
