VodafoneThree has launched a national 5G network slice reserved for business customers, using dedicated network capacity to separate enterprise traffic from consumer demand during periods of congestion.
The National Business Slice sits within Vodafone SuperMobile for Business, a new enterprise connectivity portfolio introduced just over a year after the merger of Vodafone and Three UK.
VodafoneThree describes the service as the UK’s first national business-only mobile network slice. Larger organisations will be able to access dedicated 5G+ capacity with committed performance targets using compatible standard business handsets.
The company says eligible users can receive speeds up to four times faster than its standard plans, subject to coverage, device, tariff, and service conditions. Small businesses with between one and nine employees can buy a SuperMobile business plan running over the national consumer slice for an additional £3 a month including VAT.
Network slicing uses 5G standalone infrastructure to create logically separated portions of a mobile network for different types of traffic. Instead of every user competing for capacity under identical service conditions, operators can reserve network resources for customers or applications requiring a defined level of performance.
The proposition targets companies increasingly dependent on mobile connectivity for operational systems rather than simply calls and email. Field engineers, airport workers, utilities teams, logistics operations, and employees using cloud applications can all be affected when network performance deteriorates in crowded locations.
VodafoneThree has cited Cadent Gas, Centrica, Loganair, Manchester Airports Group, Tata Steel, and UK Power Networks among organisations exploring or using advanced 5G capabilities.
Loganair head of IT Rich King said advanced 5G could “enhance operational resilience, support our colleagues on the ground”.
The company is also planning a National Critical Slice for blue-light organisations and other critical public services, with launch expected next year. A separate local slicing product introduced earlier in 2026 is intended for high-density sites including transport hubs, logistics locations, and entertainment venues.
The new services provide an early commercial test of one of the central arguments behind 5G standalone investment. Faster consumer downloads have dominated much of the public discussion around 5G, but operators have also invested on the assumption that enterprise customers will pay for differentiated performance, lower latency, greater reliability, or capacity reserved for operational workloads.
That model could alter the economics of business mobile contracts. Connectivity has traditionally been purchased primarily according to data allowance, coverage, and price. Network slicing adds service performance as another contractual dimension, moving mobile connectivity closer to enterprise networking models where capacity and availability can carry defined service levels.
The commercial value will depend on the operational setting. Slower consumer streaming during a busy period may amount to inconvenience; an engineer unable to retrieve live system data, an airport team losing communications, or an infrastructure operator facing delays during an incident can encounter a direct operating cost.
The launch sits within VodafoneThree’s £11bn network investment commitment over the decade to 2034. The merger was approved amid debate over whether combining two national mobile operators would provide enough scale for heavier infrastructure investment while maintaining competitive pressure in the market.
Services built on the combined infrastructure will therefore provide an early measure of whether that investment produces capabilities materially different from those available before the merger.
VodafoneThree has simultaneously expanded its consumer offer with Vodafone TV and premium SuperMobile tariffs, but the enterprise slice has a different commercial purpose. It attempts to monetise the technical capabilities of a standalone 5G core through committed network performance rather than treating 5G principally as a faster version of existing mobile broadband.
Wider adoption will depend on coverage, device compatibility, pricing, and whether customers can demonstrate measurable operational gains. Network slicing is now moving beyond trials into a nationally marketed business service, giving the UK telecoms market a practical test of whether differentiated 5G capacity can become a mainstream enterprise product.
