Ring, Ring! Who's that callin'? It's your Arduino! Introducing Adafruit FONA 800 Shield, an adorable all-in-one cellular phone shield that lets you add voice, text, SMS and data to your project in an easy to use pluggable shield.


This shield fits on top of any classic Arduino or compatible, and packs a surprising amount of technology into it's little frame. At the heart is a GSM cellular module (adafruit use the latest SIM800) the size of a postage stamp. This module can do just about everything.  


If you don't need the shield format, adafruit also have this is a petite breakout click here.


If you want a Shield Version with GPS, check out the Adafruit FONA 808 Shield - Mini Cellular GSM + GPS for Arduino click here.


If you just want a plain FONA, click here.


- Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested)

- 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 adafruit plated this fine module onto a shield 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 via the Arduino when necessary. Two LEDs let you know when its charging and done. You can then flip the switch and use the battery to run your circuit!

- 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 to make it Arduino-safe

- Vibrational motor (buzzer) driver so you can have noiseless notifications

- uFL connection for external antenna

- Indicator LEDs for power and network connectivity

- Any standard 2G SIM slides into a secure connector


On its own, this shield can't do anything. It requires a microcontroller like an Arduino to drive it!  You will also need some required accessories to make FONA work. These are not included!

- SIM Card! A 2G Mini SIM card is required to do anything on the cellular network. US AT&T no longer sells 2G SIMs and will shut off their 2G network, so for American customers we recommend any T-Mobile or reseller (TING, SIMPLE mobile, etc) that uses the T-Mobile network.

- Lipoly Battery - 500mAh or larger! This 500mAh battery, or this 1200mAh will work great.

- External Antenna - This slim uFL antenna works great!


Each order comes with one tested and assembled FONA shield and a stick of 0.1" male header. Required Arduino, SIM card, battery, antenna and other accessories are not included! Some light soldering is required to put the headers onto the shield. You can also grab some stacking headers if you would like to stack a shield on top.


There's also some recommended accessories. They are not required but chances are you'll want them!

TRRS 4-Pole Headset - Any 'iPhone' or 'Android' compatible (but not iPhone original) should work. Adafruit tried about 10 different ones, and basically the more expensive once are more comfortable and louder but our official iPhone headset mic did not work.

External Mic & Speaker - If you want to talk directly to your FONA, an electret mic and mini 8 ohm speaker will do quite nicely.

Vibrating motor - the FONA can drive this directly, just solder a mini vibrating motor disc in!

Revision History:

- As of January 18, 2016 adafruit have replaced the SIM800L module with SIM800H which is backward compatible. Note that this board design does not have a bluetooth antenna on it so you cannot use the BT capabilities of the SIM800H
