I'd call my friends in Green Bay that I only get to talk to here and there and then I'd call my grandmother. Might even mean I have money to take a trip to Green Bay and see the kids.
With that kind of calling credits, I'd be calling everyone I know, twice. Heck, Since I have so few friends, I could probably call them all 20 times each...
I would call a friend who I met over last summer who is in germany. We only get to talk over im and every once in a while on skype. How great would it be to call her cell and have a normal conversation. You really miss the small thing when they are gone
I would use the credits to make a couple of calls to my brother in Israel if I can use the credits for that since we don't get to verbally chat that often.
Would love to be able to call some good college friends overseas. One teaching English in Japan and another in Germany. Wouldn't mind giving a shoutout to troops overseas!
