Updated at 11.30AM: It seems that some M1 customers are facing problems with mobile data connectivity. A Facebook user, Chew Loh Seng shared on our Facebook Page that he had no voice, SMS and data over 2G/3G networks although 4G service is not affected. We also received a screenshot from a reader showing his iPhone with no service signal.
M1 reported on its Facebook Page an hour ago that some customers are having problems sending text messages or making voice calls.
The telco states that it is addressing the issue and apologize for the inconvenience. At time of publication, the post has garnered over 1,000 comments and 645 shares.
Since October 2013, M1 customers had experienced two service outages. On October 16 last year, 3G services were down for M1 customers in many areas and the cause of the problem was due to a radio network controller that the telco upgraded.
On December 2, some M1 customers experienced intermittent access with mobile data in the morning which was resolved later in the day. M1's preliminary findings suggest that a software bug prevented some customers from connecting to the mobile data network.
Less than two weeks ago, the Infocomm Development Authority (IDA) of Singapore imposed a fine of $25,000 on M1 for failing to meet some of its outdoor coverage requirements.
