Spark Devices negotiated with Telefonica for $3/1mb/mo global data plans. Maybe the bigger question is... why can't there be cheaper data plans available.

$3 a month? That's really expensive for essentially a dumb button. Why would you bother with a 3G modem if you can just use someone's Wi-Fi? Especially since there's probably no GSM signal in your laundry cupboard,but a wifi router will be nearby.

Depending on which product is being bought with these $3/month could be Amazon's net profit on what gets bought with these things in a month.
