U Mobile has expanded its 5G network coverage to 90% of Malaysia's populated areas, according to Telecompaper, marking the operator's arrival at a milestone figure the country's regulators have used as the benchmark for nationwide 5G deployment.

The coverage number is the hardest fact in the story and the most consequential. Ninety percent of populated areas is the threshold Malaysian authorities set when they restructured the national 5G model, and U Mobile now reports it has reached that level on the network it is deploying.

What does 90% coverage mean for Malaysian users?

The metric counts populated areas rather than geography or population alone, a formulation Malaysian regulators have applied since the country began rolling out 5G. For subscribers, reaching 90% means the large majority of centres of habitation — cities, towns and developed rural districts — now fall within the operator's 5G footprint.

For U Mobile, the figure signals that its own network build has moved from launch phase to near-nationwide scale. Coverage milestones of this kind typically shift an operator's focus from rollout speed toward capacity, indoor penetration and subscriber migration from 4G.

How did U Mobile get here?

U Mobile is one of the Malaysian operators building its own 5G infrastructure under the country's revised approach to next-generation networks. The operator has been expanding its footprint steadily, and the 90% figure represents the cumulative result of that build.

The achievement places U Mobile among the operators whose standalone 5G efforts now span nearly the entire populated territory of the market, rather than relying on partial or urban-only deployments.

Why does this matter for Malaysia's dual-network model?

Malaysia's 5G strategy has evolved from a single wholesale national network toward a model in which operators deploy their own infrastructure. Coverage figures like U Mobile's 90% are the key progress indicators for that transition: they show whether competitive, operator-led builds can match the coverage targets originally set centrally.

A second operator-grade network reaching near-universal populated-area coverage strengthens the case that the dual-network structure can deliver both competition and reach. It also raises competitive questions for rivals, which now face a market where at least one competitor can offer 5G across almost the entire country.

What comes next?

The remaining 10% of populated areas will likely prove the hardest and most expensive to cover, as final-footprint expansion typically involves lower-density and harder-to-reach locations. Closing that gap, along with converting coverage into active 5G subscribers, will define the next phase of U Mobile's rollout.
