Smaller Providers and Other Carriers in Princeton

Mobile Virtual Network Operators (MVNOs) are smaller providers that don't own their own network infrastructure.⁷ They lease access from the major carriers (AT&T, Verizon, T-Mobile). This allows them to offer more affordable plans, often with fewer extra features or potentially slower data speeds during network congestion.

Smaller Providers on AT&T's Network:

• Cricket Wireless: An AT&T-owned MVNO offering unlimited plans, often at lower prices. Data speeds might be slower when the network is busy.
• Consumer Cellular: Designed for older adults, providing flexible and affordable plans.
• Boost Mobile: Uses multiple networks, including AT&T (and T-Mobile and now its own).
• Red Pocket Mobile: Offers plans on all major networks, including AT&T.
• US Mobile (Dark Star): Customizable plans, now with AT&T access.

Smaller Providers on Verizon's Network:

• Visible: Verizon's own budget brand, known for simple, unlimited plans. The Visible+ plan offers high-speed data on Verizon's 5G Ultra Wideband, while the basic Visible plan might see slower speeds during busy times.
• US Mobile (Warp): Offers customizable plans, focusing on high-speed data on Verizon's network, with an option for priority data.
• Xfinity Mobile & Spectrum Mobile: These MVNOs are exclusive to existing internet customers of Xfinity and Spectrum, respectively, offering competitive plans on Verizon's network.

What You Might Notice with Smaller Providers: While MVNOs offer good value, the main trade-off is often data deprioritization. When the network is crowded (for example, during peak hours on campus), MVNO users might experience slower speeds compared to direct customers of the major provider. Some MVNO plans also have strict data limits or lower video streaming quality.
