M1 has announced that the company has restored full 3G service in the affected areas yesterday.
To express its sincere appreciation to the affected customers for their patience and understanding, M1 is offering all postpaid customers three days of free local mobile calls, SMS, MMS and data services from 10th to 12th February 2013. This will commence from 00:01 hours on 10th February till midnight on 12th February 2013. M1 prepaid customers will enjoy a S$1 bonus for every top-up of S$17 and above, during the month of February 2013.
This is M1's second service outage in less than two years and is probably the worst Singapore has faced so far. A transmission equipment upgrade done by one of its vendors at 3 am, Tuesday morning, sparked off a power incident at its network centre, which set off the gas suppression and water sprinkler systems.
This in turn caused an outage at one of its mobile network switches, and affected the 3G network entities connected to the switch. Many M1 customers faced reception issues over the three-day period.
