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 & Genuino UNO

Other Arduino versions should work as well, like Arduino Mega and Leonardo!
×1
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
3.7V LiPo Battery (500mAH+)
This is optional for SIM7000A users but is required for GSM use with the C and E versions! Ideal capacity is 1000mAH or greater. You can find these at Sparkfun or Adafruit with JST connectors.
