About these recommendations

Our plan picks start at 300 Mbps to leave room for simultaneous use. These are practical starting points, not minimum requirements or performance guarantees. Lighter use may need less. 1 Gig = 1,000 Mbps.

For context, Netflix recommends 15 Mbps for one 4K stream. Zoom recommends 3.8 Mbps upload and 3 Mbps download for 1080p calls. Your total needs depend on what runs together.
