What is a Virtual Operator?

A Virtual Operator, or Mobile Virtual Network Operator (MVNO), is a mobile service provider that offers phone and data plans without owning its own network infrastructure. Instead, it leases access to established networks like EE, Vodafone, or Three, allowing it to provide coverage at a lower cost. MVNOs can offer cheaper pricing, flexible plans and higher data allowances.
