The GSMA’s Mobile Alliance Against Child Sexual Abuse Content was founded by an international group of mobile operators within the GSMA to obstruct the use of the mobile environment by individuals or organisations wishing to consume or profit from child sexual abuse content.

All members of the Alliance commit to working closely with their national hotlines. Hotlines play a key role in the fight against online child sexual abuse content. This guide, developed in collaboration with INHOPE (the international umbrella organisation for national hotlines), details processes for setting up and managing a hotline, and is intended to support organisations in countries which do not yet have such a facility.
