Mary wants to know about alternatives to Jajah, a VOIP service that she's been using and is going out of business.
Leo says Skype is one solution and she can use Skype with a phone number on a mobile phone with the app. It's very inexpensive. She can buy a Skype Out account, and that lets her make calls to regular phones. Leo did that with his daughter when she was studying overseas. Mary is worried about governments listening in when she calls overseas. Leo says that unless she's Jason Bourne, nobody really cares.
Other options include Talkatone, Tango, and even Google Voice. Skype In allows users to call her from any phone, and Skype Out lets her call anyone else. Since it's owned by Microsoft, it's going to be around for awhile.
