Three give these hidden deals to comparison websites like us to share with our readers. They're typically much better priced than their regular plans, and there are sometimes some unique data amounts too.
Mobile providers do this to provide potential customers looking for the best possible deal a reason to join them without giving away their best discounts to regular customers.
