SingTel announced earlier this afternoon it has spent $150 million over the last year to complete its nationwide deployment of its high speed 4G mobile network, joining M1 as the second telco to reach nationwide coverage.

The high speed network now covers 95 per cent of the island, including over 800 outdoor locations on street level and over 500 indoor locations such as shopping malls This, however, does not extend to the underground MRT network, parks and reservoirs.

Last September, M1 was the first telco here to announce nationwide coverage for its LTE network. StarHub is currently at 60 per cent coverage, and expects to complete its nationwide coverage by the end of this year.

SingTel's 3G network speed has also been upgraded from 21Mbps to 42Mbps. Customers who are still on the 3G network and using devices that support the higher download speeds will receive the upgrade progressively over the next few months.

Over 300,000 subscribers have signed up to SingTel's 4G network in a period of nine months since it first announced the roll out of its LTE network, while M1 currently has 223,000 subscribers for its 4G network as of March 31. StarHub declined to reveal its number of 4G subscribers.
