Once the reader design is built, the open source software can be used to read from and write to the card. Together they can be used to backup/restore stored SIM card data, recover deleted SMS's and phone contacts, examine the last phone numbers dialed, etc.
There are a few tools that are required for assembly. None of these tools are included. If you don't have them, now would be a good time to borrow or purchase them. They are very very handy whenever assembling/fixing/modifying electronic devices! I provide links to buy them, but of course, you should get them whereever is most convenient/inexpensive. Many of these parts are available in a place like Radio Shack or other (higher quality) DIY electronics stores.
|Soldering iron. One with temperature control and a stand is best. A conical or small 'screwdriver' tip is good, almost all irons come with one of these.|
A low quality (ahem, $10 model from radioshack) iron may cause more problems than its worth!
Do not use a "ColdHeat" soldering iron, they are not suitable for delicate electronics work and can damage the kit (see here)
Check out my recommended basic soldering iron and where to buy.
|Solder. Rosin core, 60/40. Good solder is a good thing. Bad solder leads to bridging and cold solder joints which can be tough to find. Dont buy a tiny amount, you'll run out when you least expect it. A half pound spool is a minimum.|
Check out my recommended basic solder and where to buy.
|Multimeter/Oscilloscope A meter is helpful to check voltages and continuity.|
Check out my recommended basic multimeter and where to buy.
|Flush/diagonal cutters. Essential for cutting leads close to the PCB.|
Check out my recommended basic diagonal cutters and where to buy.
|Desoldering tool. If you are prone to incorrectly soldering parts.|

|'Handy Hands' with Magnifying Glass. Not absolutelynecessary but will make things go much much faster.|
Check out my recommended basic 3rd hand tool and where to buy.
|Good light. More important than you think.|
