Satellite TV and Internet Providers

Satellite TV is generally a good choice for customer service and channel selection. DIRECTV and DISH are ranked above traditional wired TV providers in almost every survey and study done. If you're not sure which provider is best, make sure to read our DISH vs. DIRECTV comparison.

Satellite Internet (like HughesNet) should be a last resort. Latency is often very high, making it impossible to live stream video or play games. For rural customers with no wired internet service, HughesNet is likely the best option.

About DIRECTV

DIRECTV, now owned by AT&T, is often ranked first in TV service. DIRECTV won JD Power's most recent survey in the East and South regions for customer satisfaction, beating cable companies by a wide margin. DIRECTV does not have an Internet option. If DSL or cable is available, we recommend choosing wired Internet and satellite TV. If no wired services are available, customers can set HughesNet and DIRECTV up separately.

Viasat offers the best service in your area by default, making it an obvious call for those in rural areas.

 

Mobile (Cell) Internet Providers

Mobile/wireless data service is often marketed in a way that makes it hard to compare. We've included access charges and unlimited talk/text on cell phone plans as well as autopay/paper-free discounts to show what you'll actually pay for the listed data. Monthly payments will be higher if you choose a subsidized phone.

Consider mobile internet as your primary access if: (1) no wired providers are available; (2) your data usage is light (few videos); and, (3) your computer or main device can connect to 4G or connect wirelessly using your phone as a hot spot. 4G data is often faster and much lower in latency than satellite internet. You can connect using a hotspot, but it's generally a better idea to buy a cellular modem.
