StarHub users in the eastern and western parts of Singapore may have problems making or receiving calls on their mobile phones today.
Following complaints from consumers, the telecom operator said at about 11am today that it was facing intermittent issues with its mobile voice services.
In a post on its Facebook page, it said it was working to restore the services as quickly as possible. It did not state the reason for the disruption.
About an hour before, some users had taken to the Internet to say the mobile network was not accessible. Some could not make calls while others said they did not see a network signal on their phones.
Singapore’s telecom infrastructure had come under scrutiny last year after a number of high-profile outages. After hefty fines, including a record S$6 million for one operator – SingTel – operators had promised network upgrades and improve contingency plans.
UPDATE: StarHub said it had restored the services by 5.30pm on November 12. It is investigating the cause of the outage.
