Not all providers are available at every household even if they’re available in your general area. Once you enter your address to browse the providers available at your location, consider other factors such as price and speed.
Price: Evaluate the price of internet deals while keeping speed in mind. Some providers offer better value, but account for extra costs like equipment fees, installation fees and price increases. Spectrum offers one of the cheapest internet options in San Diego, providing cable internet at 100 Mbps for $30/mo. This is an excellent choice for households looking to save money on internet.
Speed: Some internet activities, like gaming, streaming, working from home or downloading large files, require more bandwidth. If you often engage in these activities, choose a higher internet speed. AT&T offers the fastest internet in San Diego with fiber speeds up to 5 GB.*
Number of devices: When choosing an internet speed, consider the number of devices connected to your network, the number of people in your household and your daily internet activities. More people and devices require higher speeds to avoid network congestion and spotty Wi-Fi.
