FonYou

With the FonYou application, you can create another, additional number of your iPhone device and its telephone number. This randomly generated number will prove ideal for use on social networks and other registration pages because the actual phone number will always be anonymous.

The registration process for FonYou is quite easy. You just enter your ID number as a username and select a password. (This process is necessary for security reasons to avoid using dozens of phone numbers for suspicious validity.)

Once you create your 'imaginary' telephone number, you can connect your real number with all the calls and messages received through your iPhone, which will usually reach your original number.

FonYou is a very interesting tool that will save you many headaches when you come to reveal your actual telephone number. Also, this app makes it possible, for example, using WhatsApp without a SIM card.
