MVNO stands for Mobile Virtual Network Operator. It's a company that provides SIM services, similar to traditional carriers like Singtel, but with a key difference: MVNOs don't own their own cell towers or infrastructure.

Instead, they lease network capacity from the Mobile Network Operators (MNO) at wholesale rates. This allows them to offer SIM subscription plans to consumers, often at lower costs than traditional Telco.

mDR Limited (mDR) is the holding company of Handphoneshop Pte Ltd, which operates the ZYM Mobile brand.
