SingTel has fully restored its various SMS services following an outage which lasted nearly half a day.

On Sunday evening, some of the Singapore telco's customers could not send nor receive SMS. Many of the took to the company's Facebook page to air their complaints. 
“Some customers may have experienced intermittent difficulties in sending and receiving SMS from approximately 10.30pm Sunday.  Our engineers worked through the night to restore sending and receiving capabilities for postpaid and prepaid customers by 6.10am Monday," a SingTel spokesperson told ZDNet.

SingTel eventually fully resolved the outage, restoring applications-based services such as *send, SMS notifications and billing alerts at 11.10am.

SingTel customers complain on its Facebook page.

The incident follows a more serious outage affecting M1 customers in January, where customer could not access services for voice and data. M1 blamed the disruption on a power fault triggered by one of its vendors during an upgrade of equipment. Services were fully restored only after 64 hours.

Both telcos, along with the third player StarHub, were also fined S$10,000 (US$8,911.40) each last December, for failing to meet the quality of service (QoS) standards for 3G coverage.
