The Rent A Cell Company aggressively sells to English-speaking people landing at Lima airport. Since I do not speak Spanish and a Rent A Cell rep spoke English, I thought I would avoid a hassle by buying it here. We asked a lot of questions and they were answered. Our important requirement was to call the US but it did NOT work. She said we should dial 1912 00 1 and then the US phone number. We tried at least 20 times and the call never went through. After a dozen calls to their call center, we found one English-speaking customer service rep. She asked us to dial the US number without the area code of the US phone number. Clearly, she did not know anything. We wasted buying two SIM cards and God knows what charges they are going to slap when we return.
My Peru cell phone number given by Rent A Cell is 987561108. If the company is a legitimate one that is not in the business of duping unwary customers, I would expect them to call me and fix my problem. I will post back to you in a few days.
