Hello.

I wonder how do cellulars connect to internet wirelessly?

I want to implement such capability in my product but have no idea how it works.

Thank you in advance for helping.

Well you can't DIY a GSM modem. You can buy one though.

Hello.
Thank you for commenting.

In order to control my product from the web, I need to implement a GPRS modem in it?
For example, do cellulars comprise GPRS modem inside their enclosure?

Well the GPRS modem is just that, a modem. You'll still need to pay a monthly fee for the service. It's a really popular student project in India where I assume cell phones are cheap as dirt to operate.
Lots of links on the web.

Something like that. Your PC will need a way to talk to the GPRS modem. SMS seems to be popular.

Thank you Blue.

I was trying to download the firmware and schematics of this project, but it seems that the download page of this project is under construction.

Could you post please links to microcontrollers-GPRS projects that share firmware and schematics?
