Introducing Adafruit FONA MiniGSM, a all-in-one cellular phone module that lets you add voice, text, SMS and data to your project in a small mangeable package.

Measuring only 1.75"x1.25" but packs a surprising amount of technology into it's little frame. At the heart is a GSM cellular module (we use the latest SIM800) the size of a postage stamp. This module can do just about everything. This version has an SMA connector. For the uFL version, click here!
