Business DSL (Digital Subscriber Line) is a widely available and cost-effective internet service. It provides a range of speeds that are suitable for small to medium-sized businesses as well as remote workers. DSL is similar to cable but it works through your phone line. DSL is ideal for businesses that use VoIP.

Why We Chose Verizon DSL, AT&T DSL, and CenturyLink DSL:

Verizon DSL offers great service with affordable pricing. They have a wide coverage area, with easy installation and consistent, reliable, and fast DSL connectivity.

Some DSL plans include access to a wide network of WiFi hotspots as well as great customer support and complimentary storage space. Verizon DSL also features added security options for a small additional fee.

You can bundle your internet with phone and other services and there are multiple bundle packages available. Verizon DSL also does not require a contract.

AT&T DSL is our second choice as it is a cost-effective solution that offers coverage across more than 20 states. While AT&T's DSL speeds are not very fast, they do have high data caps.

Our third pick is CenturyLink DSL as they offer coverage over a wide area and have fast internet speeds. CenturyLink's DSL is reliable but they have low data caps.

Things to Consider When Evaluating DSL Providers:

  1. One of the biggest considerations for businesses purchasing internet is accessibility. Service providers do not cover all areas and some areas only have limited options in the type of internet that you can get.
  2. Look for service providers who have central offices near your business. The further away you are from the central office, the slower your DSL connection will be.
  3. While DSL is reliable, it's not the fastest internet option. Evaluate your business needs and see if DSL will work for you or if you will need a faster connection.

Verizon and CenturyLink are both month-to-month internet providers whereas AT&T requires a 1-year contract. However, both CenturyLink and Verizon only provide their DSL services bundled with a phone plan. Compared to Verizon, CenturyLink offers a wider range of coverage, servicing 39 states while Verizon only covers about 11. CenturyLink also offers higher internet speeds than Verizon but their data caps are much lower. Online reviews also suggest that Verizon's customer service is much better than CenturyLink's.

While AT&T does require a 1-year contract, they offer good rates for their services and are the cheaper option compared to CenturyLink and Verizon. They also, however, have the lowest speeds. AT&T's data caps are higher than CenturyLink's but their coverage is slightly smaller. However, their coverage does not overlap very often with CenturyLink's, so users will sometimes not have this choice.

Pros and Cons:


  • High-speed internet.
  • It is inexpensive.
  • You do not share your internet connection, so you will not suffer from peak usage periods where your connection slows down.
  • DSL is more secure than cable as you don't have to share the line.
  • It uses your existing telephone wiring, so you don't need to buy expensive upgrades or additional wiring.


  • The further you are from the provider's central office, the slower your internet speed will be, but you will still pay the same price.
  • It is only available in limited distances from the provider.
  • If your phone usage is heavy, you may experience lags in the internet connectivity.
  • Uploads are slower than downloads with DSL, so it isn't suitable for companies with high upload volumes.
