because i have family there, and i wanna help them at the same time i get into the business world ;)

ronny_fcbm,

why would you send them to Central America?

I live in Central America and i have family in both Miami and Los Angeles. They have their way of getting brand new phones, they send them to me, here in Nicaragua, and i provide them to people who need them. I don't sell them for too much money, as you know, people in Central America don't make millions a month.

Yes, t-mobile and Cingular (now AT&T) phones are the only phones you can use here. The "sim card" is a little card that going in the back of the phone by the battery. Its like a "memory card", it stores you contacts, music, text messages, and things like that (depending on the memory on it) and most importantly its like the chip that controls the phone.

When i get them here, i go to a place where i get them "unlocked", then anyone can use the phone by buying a pre-paid sim card or just a new plan. Its simple. The phone companies that don't have use sim cards are Sprint and Verizon, and other non-big names. I have an iPhone, but i haven't used it yet, just got it a week ago. But i do use a Cingular 8125 and Sony Ericcson W810i, they are both from Cingular and use a sim card. Click on the links below and it will explain some more.
