Facebook Zero is an initiative undertaken by social networking service company Facebook in collaboration with mobile phone-based Internet providers, whereby the providers waive data (bandwidth) charges (also known as zero-rate) for accessing Facebook on phones via a stripped-down text-only version of its mobile website (as opposed to the ordinary mobile website m.facebook.com that also loads pictures). The stripped-down version is available online only through providers who have entered the agreement with Facebook. Photos are not loaded by default. Users may still choose to view them by clicking through but regular data charges apply to photo use.
