I have googled, searched, talked with several different cell phone companies and still not sure the most cost-effective way to call the United States from Peru. Our son will be there for 3 months (school internship) and I think our current cell phone won't work there (Verizon). We could get a global phone to use but then it costs almost $3.00 PER MINUTE and 50 cents for each text. We don't plan on talking often, but want to stay in touch. I read he can buy a phone there that he can use to call the US, but I could not find any information on costs. If anyone has any insight, I would appreciate your comments. Thanks!!
