The "Mobile operators' enables the phone number to get information:
date of registration (company)
the official website of the Operator
page for sending free SMS
With this information, you will always know who and where you call or write SMS. ;-)
Before you call a cell phone, we strongly recommend you learn from this program, which region and mobile operator belongs to the specified number in the ad. Otherwise it may happen that your call (to another region) will cost you too much.
In addition, you can quickly and simply send a free SMS to any number.
The program requires no installation, can run directly from a flash drive or CD.
