Build your own cellular project and get off the grid with FONA. This pack comes with an SMA-antenna type FONA and paired with hand-picked accessories. It's the Adafruit FONA - SMA Starter Pack.

The FONA miniGSM is an adorable all-in-one cellular phone module that lets you add voice, text, SMS and data to your project in an adorable little package.

This module measures only 1.75"x1.25" but packs a surprising amount of technology into its 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 starter pack has an SMA connector. For the uFL version, click here! And for the Adafruit FONA 800 uFL Shield version click here!

Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (Note that not all countries have working 2G networks, there is no USA 2G network anymore)
Make and receive voice calls using a headset OR an external 8Ω speaker + electret microphone
Send and receive SMS messages
Send and receive GPRS data (TCP/IP, HTTP, etc.)
Scan and receive FM radio broadcasts (yeah, we don't exactly know why this was included but it works really well)
PWM/Buzzer vibrational motor control
AT command interface with "auto baud" detection

Sounds delicious, right? So we plated this fine module onto a little breakout with all the extras you need to make your next project shine:

Onboard LiPoly battery charging circuitry so you can take your project on the go. Use any 500mAh+ LiPoly or LiIon battery and recharge over the MicroUSB when necessary. Two LEDs let you know when its charging and done
Standard 4-pole TRRS headphone jack. Use any 'Android' or 'iPhone'-compatible headset with mic
Breakouts for external 8Ω speaker and electret mic if you don't want to use a headphone
Level shifting circuitry so you can run it with 2.8V to 5V logic.
Vibrational motor (buzzer) driver so you can have noiseless notifications
SMA connection for external antenna
Indicator LEDs for power and network connectivity
Standard SIM slides into the back

On its own, this module can't do anything. It requires a microcontroller to drive it! We suggest and use an Arduino but any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.

Microcontroller not included! We recommend an Arduino UNO to go along SIM card not included!
