SINGAPORE - In celebration of Singapore's Golden Jubilee, telco M1 will be offering its customers free voice calls, SMS/MMS messages and mobile data for local usage over the four-day National Day weekend.

Both M1's post-paid and pre-paid customers will enjoy the offer, which will take effect automatically after midnight on Aug 6 and will end at midnight on Aug 10, the telco said in a statement.

M1's Chief Marketing Officer, Mr P. Subramaniam, said: "Singapore is widely acknowledged to be one of the world's most connected societies, and we are proud to be part of this remarkable story for the last 18 years.

"As a Singapore company, we want to do our part to mark this milestone celebration, and what better way to do that than allow our customers to freely share their joys and wishes for our nation with each other, on this very special occasion," he said.

The telco, which was established in 1997, has close to 2 million customers.

Aug 7 was declared a public holiday in March by President Tony Tan Keng Yam, as part of Singapore's 50th birthday celebrations.

The extra holiday falls on a Friday. With Monday already a holiday since National Day falls on a Sunday this year, Singapore will have a four-day Golden Jubilee weekend from August 7 to 10.
