"Unfortunately the answer is no. President Obama doesn't, but previous presidents have called on me," Carter, 89, said.
The 39th president, who is promoting a new book, Call to Action, also said that he regularly uses snail-mail to communicate with foreign leaders.
“I have felt that my own communications are probably monitored,” he said of the National Security Agency. "When I want to communicate with a foreign leader privately, I type or write the letter myself, put it in the post office and mail it, because I believe if I send an e-mail, it will be monitored."
