FYI: Hologram are currently offering a ‘developer special’ deal for a "free" Developer SIM card.

https://hologram.io/store/developer-global-iot-sim-card/ <https://hologram.io/store/developer-global-iot-sim-card/>

(normally US$5 value)

Limit is one per developer, and overall numbers are limited. The SIM is free, but you will need to pay for shipping.
