Calling toll-free numbers: American toll-free numbers dialed from Cabo are usually blocked by the local phone companies (who get no revenue from the connection).

Anyway, passed on to us is a way to bypass the blocks. For 800 numbers, dial 011-880, then the number; for 866 numbers, 001-883 then the number; for 877 numbers, dial 001-882 then the number and for 888 numbers, dial 001-881 then the number.
