SINGAPORE - Many StarHub customers were cut off from mobile services for up to eight hours yesterday, in what was the second mobile disruption in Singapore this year.
In a statement last night, the telco said all affected network services were restored at 5.30pm. StarHub said that 4G customers were not affected.
Customers first reported problems in making and receiving calls as early as 9.30am. StarHub acknowledged the problem on Facebook shortly after 11am, saying voice services of customers in the eastern and western parts of Singapore were intermittently disrupted. It said mobile data and SMS services were not affected.
But users in the northern and central areas - including Bukit Batok, Woodlands and Orchard Road - were also complaining about connection problems.
Pockets of users also complained about not having data connection. In its media statement, StarHub said data connection disruption, which started at 2.30pm, was restored at 5.30pm.
The Infocomm Development Authority said in a Facebook post at around 4.30pm that it was investigating the issue.
In February this year, many M1 users could not make calls for six hours. This was due to call congestion that arose from equipment experiencing intermittent connection problems while authenticating mobile users. This was not related to a 71-hour mobile service disruption in January last year, for which M1 was fined $1.5 million.
