I am doing a project on OTA programming of Arduino at remote place so I need GSM along with Arduino, so how can we do OTA with gsm for Arduino?

I assume you're asking how you can remotely control an Arduino with your phone, right?
I suggest using Bluetooth for this, as it is build into every phone nowadays. You'll still have to buy a module to allow the Arduio to communicate via bluetooth. An example of such a module is the HTC-06, wich can be bought online for less then $10 and for wich there is an exellent tutorial over at instructables.
The phone side of the story depends on what kind of device you're using, this is the official Android documentation, this seems to be the Apple documentation.
Alternatively, if you don't want to write everyting yourself, you can use an app like Tinkernut does is one of his videos.
