Click the Download link: Download iTelMobileDialer.
Follow the onscreen instruction and install it in the 'Phone memory' instead of 'External Memory' (if you install the mobile dialer in storage memory, then the program will request operator code, and PIN information for every run of the software, whereas if you install it in phone memory, it will require above information only for the first time.)
Open your installed iTel Mobile Dialer from your handset's 'Installation' or 'Application' or 'My own' folder.
Type your service provider's Operator Code (every service provider who is registered with iTel Mobile Dialer has been assigned an Operator Code).
Then select internet connection option which may be GPRS or WiFi.
Then set your valid PIN and Password.
Now wait for PIN registration after that dialed your desired number from iTel Mobile Dialer.
