Insights

5G Expansion O2 is actively expanding its 5G Standalone and 5G+ services across multiple regions in the UK, including Suffolk, Surrey, and the West Midlands. This presents opportunities to offer enterprise connectivity, edge computing, and private network solutions to local businesses, public sector customers, and regional developers in newly covered areas.

Enterprise Partnerships The collaboration with Cellnex to tackle 5G not-spots indicates a willingness to partner on infrastructure and network reliability. Potential sales angles include managed network services, fleet connectivity, and IoT deployments for critical operations that require consistent coverage and SLAs.

Mobile Broadband Growth The launch of 5G Standalone mobile broadband across wider counties signals an opportunity to upsell to mid-market and SME customers needing high-speed, low-latency wireless connectivity for remote sites, remote workers, or disaster recovery setups.

Customer Engagement O2 Priority’s spin-to-win mechanic and new consumer app features indicate a strong emphasis on loyalty and engagement programs. This supports cross-sell of premium data plans, bundled services, and targeted marketing tech for retail partners and local businesses looking to reach engaged audiences.

Media and Sponsorship O2’s sponsorships and media presence, including The O2 venues and a music-focused YouTube series, create entry points for branded content, sponsorship-enabled campaigns, and B2C marketing collaborations with retailers, venues, and event organizers seeking elevated brand experiences.
