If you are a U Mobile customer, the 5G signal on your phone now runs on infrastructure the telco owns and operates itself. As of 1 July 2026, U Mobile has moved all of its customers onto its own nationwide ULTRA5G network, closing the chapter where its 5G rode on a shared wholesale network.

What actually changed
The shift follows U Mobile's exit from its wholesale access agreement with Digital Nasional Berhad (DNB), the government-backed company that built and ran Malaysia's first single 5G network. With that agreement now ended, U Mobile delivers 5G entirely through its own towers, spectrum and equipment rather than leasing capacity from DNB.
For most users the change is meant to be invisible on day one: your existing plan and SIM keep working. What it does is hand U Mobile direct control over how its network is tuned, priced and expanded, which is where the company says the difference will show up over time.
Malaysia's two-network era
This is the practical result of a policy decision made in 2025. The government selected U Mobile as the country's second 5G network operator, ending DNB's run as the sole nationwide 5G provider and moving Malaysia to a dual-network model. The thinking is that two competing networks push each other on coverage, price and service.
U Mobile started building in July 2025 and has moved quickly since. It says it has passed 85% coverage of populated areas (CoPA) and was recognised by the Malaysia Book of Records for the fastest 5G network rollout in the country. It has also pointed to more than 190 in-building coverage sites in places like transport hubs, shopping malls, hospitals, offices and government buildings, where 5G signals are usually hardest to hold.
Why it matters for you
Indoor coverage and network features are where the competition is likely to be felt. U Mobile has said it is the first in Malaysia to offer on-demand 5G network slicing, a way of carving out a dedicated slice of the network for a specific use such as a live broadcast or a large event. Running its own network makes it easier to build services like that without waiting on a shared provider.
The caveat worth keeping in mind is that a network is only as good as the coverage where you actually live, work and commute. A completed migration and a high coverage figure are a solid starting point, but the real test is everyday performance on your regular routes.
The takeaway
Malaysia now genuinely has two independent 5G networks competing for the same customers. For U Mobile users the immediate effect sits behind the scenes, but it sets up the more interesting question of whether a two-network market delivers better 5G for everyone.
