This version (FONA-2) has currently (Mar-2020) been replaced with FONA-2.5, which uses an Arduino Teensy as Basement Monitor instead of a Nano.
Both FONA-2 & FONA-2.5 interface a FONA breakout (Adafruit 2542) to Arduino Mega 2560.
The FONA-2 uses an Arduino Nano ("basement monitor") as interface to real-world sensors.

Notes:

• Interesting that, in contrast to FONA-1, NTP time synch works on this one.
• This is a cellular 2G device
