DMSL Security Policy Statement

Established in 2012, Digital Mobile Spectrum Limited (DMSL) is a joint venture of the UK mobile network operators EE, Three, Virgin Media O2 and Vodafone. Our vision is a disruption free digital life for people across the UK. DMSL helps make this a reality by connecting people to communications and media networks and removing barriers to access.

We specialise in transparently delivering complex programmes with multiple public and private stakeholders. Utilising our expertise in radio modelling, customer experience and TV coverage planning, we support our stakeholders in achieving their shared objectives through our TV interference mitigation and rural connectivity programmes.

TV interference mitigation: DMSL runs the Restore TV programme, which provides advice and support to viewers whose TV service may be disrupted by the rollout of mobile services in frequencies that were previously used for TV broadcasting.

Rural connectivity: DMSL manages and runs the Total Not Spots (TNS) element of the Shared Rural Network (SRN) programme which will make 4G mobile coverage available to 95% of the UK by the end of 2025, offering significant improvements to mobile coverage in rural communities and providing long-term investment in the UK digital economy. We provide reporting and tracking information for the four MNOs, DCMS/BDUK and Ofcom. We have a leading role on all external communications and stakeholder engagement, working closely with the MNOs and their trade body, Mobile UK.

The company’s core functions include governance, programme management, IT, legal, supplier operations, procurement, quality audit, management information, relationship management, finance, HR, public affairs, marketing and communications.
