Hi, i want to know the mobile phone using as gsm module. i am very thankful to you.
Very few mobile phones are using a GSM module because of price considerations.
I know Wavecom did spend time trying to get cheap chinese phones built using their modules - was obviously a failure.
But why do you want to know that? A module isn't always so easy to use unless you get it with an evaluation kit - they often have a very interesting connector. And often nonstandard supply voltage. And often very special connector for the antenna.
So if you are going to play with a module, it's best to get one from more official channels where you can get documentation, support and needed connectors.
Do you mean, you want to use a mobile phone as a GSM modem?
ie, instead of getting a proper GSM module/modem?
I think that is a Really Bad Idea - see: www.8052.com/.../152933
"The trouble with using a phone: is that they simply aren't designed for programmatic control - and certainly aren't documented or supported for it"
If you really insist on using a phone, you are going to have to do a lot of googling to find the necessary information - so you'd better get sharpening your google skills!
Besides having problems with power on/off, pin codes, battery charging etc, the lack of documentation can be really, truly serious for phones. Embedded modules are explicitly designed for use in embedded products.
