There is nothing truly free in this world and this is especially true for our communications. SMS, WhatsAPP, Messenger, they are ideal for quick messages to those you love.

Some of this information is anonymized for the purposes of market research. Some companies share very specific details about their individual users that can be used by data brokers who build databases on individuals for resale for no specified purposes!
