Functional ** only ** the Republic of Guatemala
ID is a simple and free application, its functionality is to give the user the name of the phone company you are calling.
The idea of the application identifier came from Guatemala than 3 phone companies operate, CLARO, TIGO Movistar. The 3 companies offer free calls to numbers in the same company. For example you have a phone plan with CLEAR, you can make free calls to other numbers CLARO but as you know if the number you are calling is CLEAR. So now you can use the App ID to know which phone company is calling.
How does it work?
Simple you can dial the number of your contact, or look in the phone book on your phone. Pressing the fourth digit the application will display the logo of the telephone company you are calling.
Where it works?
Only works for the telephone numbers of the Republic of Guatemala.
