Welcome to this page on setting your numbers and opening your cell phone and what to look for when you come to connect every thing up.
9). Now you have all the things you need to modify your cell phone first we will need to load the mobile number in to the phone make sure you have the ringer set to silent all so one touch answer turned off and one touch dial or speed dial turned on.
10). It would be best to send the signal to a mobile phone when activated as they have caller display on them how this works is when the alarm system is activated it will turn on the relay and phone the number locked in the Sim card.
11). Now say if you put your own mobile number in number 5 and connected the wire coming from the relay to number five on the circuit board then this will call your mobile phone.
12). I know most Sim cards will work fine around the world if you can program different numbers in to your phone say from 2 to 9 and have speed dialling or one touch dialling set then this will work fine for you the only Sim cards I had problems with was O2 UK based company the rest worked fine.
13). Now I will open my own cell phone after you have opened it and taken out the screws you may see some thing like this as you can see from the below photo all phones have copper pads this is where we will solder our two wires from the relay if you have loaded your own mobile number in all from 2 to 9 then any one pads will allow you two connect the wire from number 2,3,4,5,6,7,8,9 pads.
In the photo above you can see the phone with case off.
In the photo above you can see how the phone buttons work the white plastic card is covered with silver buttons this is carbon and is what makes the connection to the pads to put the numbers on your screen we don't need this now.
14). Now I First need to tin the two wires before I solder them to the circuit board to do this take of the cover from the wires and very careful solder the two wires this is called tinning we do this so it is much easer to put the two wires on the pads.
The wire in the photo above has been tined and cut short as I used wire with red and black there is no need to do this speaker wire will work the same as there is no electrical connection from the relay to the pads.
15). Now look at the pads you have a in side pad and out side pad solder one wire to the inside pad be careful the inside pad does not touch the out side pad and vs or you will get a short and you will need to use cleaning tools to try and fix it. .
16). Now when you come to fix your wires to the pad put one wire in side the pad and using your soldering Iron push down on the wire this will head the solder so it fixes to the pad do the same with the next bit of wire but connect this to the out side pad.
In the photo above you can see I have soldered the two wires to the in & out side pads they look like they are touching but they are not as you will see from the video on testing the unit. You can use a test meter if you have one but if you do a good job then you don't need one.
17). Now you will need to add some PVC tape over the pads like in the photo below.
Why we add the PVC tape is to stop the carbon buttons from the plastic carbon track touching the circuit or you can just remove it.
Please note it is very important you only use a small amount of tape as mobile phones have LEDs Light Emitting Diodes around the circuit this is what lights the screen see photo below what to look for.
In the photo above I am pointing to one LED on the circuit they must not be covered as this will stop the light getting to the screen.
18). Now when you have put your mobile phone back together you may find it may not fit right this is normal just add some PVC tape around it this will be down to the wire coming out of the bottom of your phone.
My Modified phone with wire coming out of the bottom of it and my main phone it will send a signal from any were in the world as long as I can get a connection both ways.
19). Now I have put in my main mobile number in to my modified phone I need to add the modified phone number in to my main phone next two it and use the name some thing like GSM Alarm.
20). This is useful for when my modified phone calls me it will come on my screen as GSM Alarm now I will test the modified phone to do this just touch the two wires together and it should call your phone keep your eye on the screen of the modified phone see short video below.
Please click on the start button on the small screen.
You can down load the video here as well video here. Video size 3.71 MB
Now we will connect our modified phone in to your home or office security system to make your security system a monitored one that will send one signal when the alarm is activated. Click Here.
Now on the next page we will look at using the cell phone as a global bugging
devise and how it works Click
