U Mobile Signs MoU for 4G and 5G Coverage at Johor Customs Complex

U Mobile has signed a memorandum of understanding with Malaysia Rapid Transit Corporation (MRT Corp) to explore 4G and 5G in-building coverage at the Immigration, Customs and Quarantine Complex (ICQC) in Bukit Chagar, Johor Bahru. The Malaysian operator's 5G in-building footprint already covers more than 250 sites nationwide, and this border gateway would extend that count into one of the country's most consequential transport projects.

The complex sits near the border with Singapore and forms a key part of the proposed Johor Bahru-Singapore Rapid Transit System (RTS) Link. That line, when it opens, will carry an estimated 40,000 passengers daily. A customs hall processing that volume of cross-border traffic without dependable mobile coverage would be, to put it mildly, an awkward debut.

What does the MoU actually cover?

In practical terms, quite little yet — and that's the point of an MoU. The two parties will explore the commercial, technical and operational framework needed to deliver 4G and 5G coverage inside the ICQC. U Mobile would then connect its network to MRT Corp's in-building coverage infrastructure and extend its signals throughout the facility.

All of this remains subject to a definitive agreement, technical requirements and the relevant approvals. In other words, the antennas aren't ordered. The paperwork, at least, has started.

Who needs the coverage?

Two distinct groups. First, the travellers: the RTS Link's 40,000 daily passengers will pass through the ICQC as a transit point, and U Mobile frames reliable connectivity as essential for accessing journey information, coordinating onward transport and staying in touch with family, colleagues and businesses.

Second, the workforce. Approximately 600 government agency personnel are currently based at the complex. Their day-to-day operations would also ride on whatever network ends up threaded through the building.

What comes after basic coverage?

Beyond plain 4G and 5G service, U Mobile points to the longer game: 5G in-building coverage can act as the foundation for future 5G and AI-powered digital use cases within the complex. The operator cites smarter building operations, greater operational efficiency and an enhanced passenger experience as the potential payoff.

Read that as vendor-style ambition rather than signed scope. The MoU commits the parties to study a framework, not to deploy AI-enabled anything. Still, building the radio infrastructure first is the correct order of operations, and U Mobile clearly intends to be positioned for whatever layered services follow.

Where this fits in U Mobile's strategy

The operator describes the collaboration as part of its ongoing expansion of quality connectivity across strategic public infrastructure and high-traffic locations. The numbers back the claim: more than 250 5G IBC sites nationwide, spanning the kind of venues where dropped calls annoy the most people at once.

A cross-border gateway handling tens of thousands of daily commuters sits squarely in that category. When the RTS Link enters service, passengers will expect the border itself to be the boring part of the journey — queues, yes, but not dead zones.

The timing of any actual deployment rests on the definitive agreement and approvals the MoU defers. Both parties say the collaboration will help ensure the gateway is ready with reliable mobile connectivity when the RTS Link commences operation, which sets a clear deadline shaped by the rail project rather than by the operators' own convenience.
