Just checked in on my ebay FreedomPop sim. The sim that got me started with this wonderful free service.
At the beginning, it had plenty of unknown freedom friends to achieve 700mb a month (supposedly for life as per the ebay ad).
Right now, it is down to 9 of those friends. Maybe in another year I'll remember to check in to see what's happened to those 9. Pity I didn't do a count when I got it. I would guess it was around 20.
