Singapore’s three mobile operators — M1, Singtel and StarHub — said today they will turn off their 2G networks by 1 April 2017 and reallocate the 2G spectrum for 3G and 4G services.

Of the country’s 3.5 million unique subscribers who access mobile internet services, only 458,000 do so via 2G technology, according to GSMA Intelligence. And 2G technology accounts for only 28% of Singapore’s total mobile connection base.

Over the past couple of years the operators have run campaigns trying to encourage customers to migrate to newer networks.

In hyper-connected South Korea, KT stopped offering 2G service in January 2012 to free up bandwidth for its 4G service.

Earlier this month Norway’s Telenor announced plans to completely shut down its 3G network in 2020, five years before it closes 2G in 2025.
