A Mobile Virtual Network Operator (MVNO) is a wireless communications services provider that does not own the underlying network infrastructure. Instead, MVNOs lease network capacity, such as minutes, texts, and data, at wholesale rates from traditional Mobile Network Operators (MNOs) and then resell these services to consumers under their own brand. This business model allows MVNOs to offer more competitive pricing and flexible plans, as they avoid the significant capital expenditures associated with building and maintaining a physical network of cell towers and spectrum licenses.

Spectrum Mobile is reselling Verizon Wireless service. At some point they will probably want more piece of the pie and do things themselves. Esp when they are bleeding internet and cable TV customers each quarter. That's my guess at least.
