In this article, we are going to see how to interface GSM Module to Arduino. There are different kinds of GSM modules available in market. We are using the most popular module SIM900 and Arduino Uno for this tutorial. Interfacing a GSM module to Arduino is pretty simple. You only need to make 3 connections between the module and arduino. So lets get to business!
How to Interface GSM Module and Arduino-Send and Receive SMS - [Link]
Arduino hacked Ericsson T65 mobile phone GSM remote control. By Konstantinos Kokoras @ youtube.com:
Accepting incoming call from predifined caller and after 2 rings hungs up and turns on a device through a relay.
Also accepting incoming SMS’s from predifined caller and depending from text tuns on or off a device through a relay.
After each command execution it sends back a confirmation SMS.
Unfortunately Ericsson T65 has only PDU mode for SMS.

Check out Cooking Hacks Arduino-based GPS tracker project for vehicles that could be extremely helpful to pinpoint the exact location of the vehicle in case it is stolen. The project uses a GPS+GPRS shield with an antenna to locate the coordinates of the vehicle. You need to call the device from your preset phone number, which will be verified by the SIM908 module on the tracker, and it will then send you an SMS with the GPS coordinates of its location.

zmashiah @ instructable shows us how he build a display to easily check for his phone status, like battery remaining charge, missed calls and unread SMS. Data is transfered to an Arduino board via bluetooth. He writes:
When at home, I do not carry my phone with me everywhere… so sometimes phone rings or an SMS comes in and I do not hear that. With the volume of music played by the teenagers at home, that is not a surprise so I decided to build a small accessory that will show up the number of missed calls and unread SMS. In order to ensure it is very visible I use a 7 Segment LED display so it can be viewed from distance.

It’s small but packed with features. The GSM alarm we present today, sports a PIR motion sensor, can be battery operated and it’s capable to communicate via GSM. It can transmit alarm conditions and receive commands from remote. It’s also capable to indicate problems such as is insufficient voltage supply or tampering.
It’s not so conventional for antitheft system: to integrate a movement sensor, a PIR motion sensor and a temperature probe in a single appliance: all this accompanied by an SMS sending GSM / GPRS module. This circuit was born as a very versatile, ready to use, built-in alarm system: no installation is required, you can just drop it and it’s ready to work. It’s not by chance that is designed to be battery operated: it also features a battery state control to check the power.

Connected to a burglar alarm or fire alarm in the event of making phone calls playing voice messages. Controlled via DTMF actuators can operate on the spot.
In recent years we have introduced several telecontrols based on the SIM900 GSM module. We released schematics and code for a gate opener (that activates when receiveing a call from a given number), a GSM thermostat to manage the temperature of remote houses with simple text messages, a remote alarm control with DTMF and, last but not least, a remote alarm with I/O and controlled via calls or SMS.
Many of these tools send text messages or place phone calls in response to changes to the electrical inputs. In some cases, especially when the receiver is a human, nothing is like a voice that clearly yields you screaming “fire in progress!”, or”thieves in the house!” etc.

We create a lamp controlled by SMS using a GSM shield, a RGB shield and a Arduino UNO. Due to the simplicity of these boards, simply plug one over the other and connect a strip led to have a lighting effect. Then sending normal text messages from any phone, you can turn on and choose the color to set.

All in one GSM 3G module Quectel U10 simplifies schematics and shortens testing time thanks to a quantum of built-in interfaces. If you´re searching for a module for transfer of data, voice, video, SMS and MMS, which has everything imaginable already built-in, then the Quectel U10 is the right solution for you.
Unbelievably many functions, supported protocols, built-in interfaces and other features are provided by the new 3G module Quectel U10. Thanks to this, in the most of applications it isn´t necessary to connect any other interfaces, what decreases the production cost of a target device. Only the list of features itself would occupy the whole article, that´s why we will mention at least some of them.
The module supports dual mode and is multi-band (WCDMA & GSM) and a UMTS (HSPA) high-speed data transfer, further supported even by a high-speed USB 2.0 interface and three UART channels. CMOS camera interface with an 8 Mpx resolution enables a direct camera connection without other extra costs. All necessary can be stored into a directly connectable SD card with up to 32 GB capacity. To gain a Bluetooth communication, it is only necessary to connect an antenna to the U10. The U10 module also contains a control circuit for Li-ion battery charging, what is convenient in mobile applications, as well as when using a battery as a backup source. RIL (radio interface layer) driver for WinCE6.0 and a USB driver for WinCE 6.0, Win7/XP and Linux 2.6 further simplify a communication and connectivity. Excellent sensitivity, advanced audio algorithms and video codecs contribute to universal usage of the U10 module. So that it was possible to use all functions without limitations, a given circuit should have a wide operating temperature range – U10 meets even this requirement at 100% and has a guaranteed functionality in range from -40 to +85°C. Connection of the U10 to a PCB is very simple, by an SMD connector (board to board). The module naturally enables to use SIM cards of any GSM operator. U10EVB-KIT development kit is also available for a development support.
Basic information will provide you the U10 module specification and the Quectel U10 presentation. Detailed information will provide you the U10 Hardware Design, U10 AT Commands set, U10 EVB kit user guide and the video call application note.
U10, as well as U10-EVB kit are available directly from our stock. Guide price of the U10 module is 50 EUR at purchase of 1 pcs. Upon request we´ll let you know the exact price for your project.

Quectel launched on the market another quad-band GSM/GPRS module – M95. In an easily solderable LLC package offers M95 a reliable solution in a very compact size.
Besides all features, which can be required from a modern GSM/GPRS module, provides M95 high performance at an extremely low power consumption. M95 has a built-in class AB audio amplifier, which further simplifies hardware design of a target device. The module is able to operate reliably at an extended temperature range from -40 to +85 °C. With embedded powerful internet service protocols, represents M95 a complete solution usable as an embedded module in many M2M applications. An advantage of the M95 module is also a very competitive price. For support of development is the M95 module also available on an adaptor board M95TE-A, which can be inserted into the development kit M10EVB-KIT.
Detailed information will provide you the M95 Hardware Design, M95 AT Commands set and the M95 datasheet. M95, as well as M95 on an adaptor board, are available from our stock. Guide price of the M95 module is 11-15 Eur. We´ll let you know the exact price for your project upon request.
