A system for enabling brands to engage with mobile users having sponsored identities dedicated to those specific brands. Brands are enabled to give mobile numbers to individual users without the need of mobile infrastructure investment by the brand itself and without the need of the end user to purchase a specific mobile device or SIM and without the need for the brand to act as a Mobile Virtual Network Operator. The system therefore allows brands to engage with mobile users using dedicated sponsored identities in a much faster and more engaging way and without the need of mobile infrastructure investment by the brand itself.
