Things used in this project

Hardware components

Botletics SIM7000 Shield
This shield will include an LTE/GNSS antenna and stacking female headers. Can also buy on Amazon.com: http://a.co/d/9u2lj91
×1
Arduino UNO

Other Arduino versions should work as well, like Arduino Mega and Leonardo!

Hologram Global IoT SIM Card
Hologram Global IoT SIM Card
You can use other SIM cards as well, but I found this one to work great and the Hologram developer SIM is free! Currently all Botletics SIM7000 shields ship with a free Hologram SIM card and promo code!
×1
Adafruit 3.7V LiPo Battery
This is required for proper operation and the recommended battery capacity is 1000mAH or greater. You can find these at Sparkfun or Adafruit with JST connectors. Without this battery, the SIM7000 will power cycle, especially with more power-hungry operations like SMS and data.
