Talkster lets you make international and long-distance calls for free. The only catch is that it’s more complicated than making a regular phone call and you have to listen to a short advertisement.
Their “how it works” page will tell you just about all you need to know. Basically, you enter in the number you want to call. Both parties get assigned a new number. Then you call the 2nd party on their assigned Talkster number and tell them to hang up and call their special number, while you stay on the line. When they call the number, they hear the advertisement, then you’re connected and can talk for free, forever. If you’re doing it by cellphone, however, your standard airtime minutes will still apply.
If you’re willing to do a little work, Talkster sounds like a cheap way for far-flung families and friends to stay connected.
