Network operators
Singapore has four mobile network operators: Singtel, StarHub, M1 and Simba. They own and run the radio networks.
MVNOs
A mobile virtual network operator rents capacity on one of those networks and sells its own plans, often online-only and at lower prices.
Coverage of an MVNO generally follows its host network, though priority and speed policies may differ.
Choosing between them
Compare on price, allowances, customer support and the host network's coverage where you live and work — not just on the brand.
