The head of the GSMA has called on India's mobile operators to explore 5G network slicing as a way to deliver more tailored services to customers, signalling a potential shift in how the world's largest telecom market monetises its next-generation networks.

The recommendation came from the industry body's chief in remarks reported by CNBC TV18, and lands at a moment when Indian operators have built wide 5G coverage but are still searching for revenue models beyond consumer broadband.

What is network slicing?

Network slicing lets an operator partition a single physical 5G network into multiple virtual networks, each engineered for a specific use case. One slice might prioritise ultra-low latency for factory automation; another might guarantee reliability for fixed wireless access or enterprise VPN traffic.

The technology is specific to 5G's standalone core architecture. Operators that run 5G on repurposed 4G cores, the non-standalone configuration, cannot offer true slicing, which makes the GSMA's push a nudge toward full standalone deployments as well.

Why is GSMA pointing India at it now?

India's 5G rollout has been among the fastest globally, with operators pushing coverage aggressively since spectrum was assigned in 2022. Yet average revenue per user has not moved in step with capex, and operators are under pressure to find enterprise and premium consumer services that justify the investment.

Slicing is the industry's standard answer to that gap. Instead of selling one undifferentiated data pipe, an operator can sell guaranteed performance: a slice for a hospital's remote diagnostics, a slice for a stadium event, a slice for a logistics firm's fleet tracking.

The GSMA chief's framing — that India "should explore" slicing to offer "more tailored services" — stops short of prescribing a commercial timeline. It reads as strategic advice rather than a claim that Indian operators are about to launch sliced products.

Commercial reality versus vendor promise

Globally, slicing has spent years in the gap between vendor demonstrations and billed services. Operators in South Korea, Europe and the Middle East have announced enterprise slicing pilots and, in a small number of cases, commercial contracts, but sliced offerings remain a minor share of 5G revenue anywhere.

For Indian operators, the practical constraints are familiar: standalone core coverage, orchestration platforms capable of managing thousands of slices, and enterprise customers willing to pay a premium for service guarantees rather than best-effort data.

The opportunity is nonetheless real. India's enterprise connectivity market is growing, and tailored slices could let operators compete with cloud providers and private-network vendors on managed connectivity rather than raw bandwidth.

What happens next?

The GSMA's endorsement gives Indian operators a framework to develop slicing pilots, likely starting with large enterprise customers in manufacturing, ports and utilities, where performance guarantees carry clear value. Whether tailored 5G services move from exploration to billed offerings will depend on how quickly operators complete their standalone 5G cores and price the premium tiers.
