I am trying to find out how to call a US 1-800 number from Colombia. I have Claro phone service. I saw online many conflicting things. One place said the exit code for Claro was 00444. Then I saw the exit code for Colombia was 90. Another said it was 9007005. Each said to just then dial the 1-800 number. None of these options worked at all. Is Skype a better option? I don't have it, does it cost anything? I am willing to pay just to reach Social Security!
