Hey Kriss,
I just noticed this FreedomPop deal over at Slickdeals: FreedomPop has a deal for their Global GSM 3-in-1 SIM Kit + Global Unlimited Talk, Text, and 1GB Data Trial + Premier Service Trial + 2200 mAh Powerbank + Selfie Stick for $0.99. Shipping is free
I'm not super-smart on this stuff, but I would like to see about using Freedompop for bike tracking as well. From what I can tell by the discussion there, it looks like this can be downgraded to the free 200mb/month free plan, with extra data allowance for adding friends. Apparently there are lots of pitfalls about signing
