Best Cellular Data Speeds in Washington

Getting great coverage is one thing.

But what is the point of having great coverage if your data speeds are slow and your apps take forever to load?

There is probably not much point at all.

To help you out, we analyzed the data from our crowd-sourced speed test map, where users upload speed tests performed on each of the carriers, to determine what carrier has the fastest data speeds in Washington.

Here is what we found:

  • T-Mobile has the fastest speeds in Washington. Its median download speed is 109 Mbps. Its median upload speed is 14 Mbps.
  • Verizon is in second place. It has a median performance of 46 Mbps for download speeds and 10.3 Mbps for upload.
  • AT&T has the slowest speeds in Washington. Its median download speed is 45.2 Mbps. For upload speeds, AT&T got 9.5 Mbps.

What Affects Data Speeds?

Data speeds can be affected by various factors, including network congestion, signal strength, device capabilities, and the technology used by the service provider.

You might experience slower data speeds during peak hours when many people are using the network simultaneously, or in areas with weak cellular coverage.

Best Cell Phone Plans in Washington

Okay, now that you know the carrier with the best coverage and fastest data speeds in Washington, what cell phone plan should you sign up for?

There are a few great options.

And some of them can save you a LOT of money.

But how?

It turns out that the big carriers, AT&T, T-Mobile, and Verizon, are known as MNOs, or mobile network operators. They build and operate their own networks by putting up cell towers, laying fiber optic cable, and purchasing spectrum licenses from the FCC.

The MNOs will also sell access to their networks to MVNOs.

What is an MVNO?

An MVNO, or mobile virtual network operator, is any carrier that does not own its own wireless network. Instead, these small carriers purchase network access from AT&T, T-Mobile, or Verizon.

Popular examples of MVNOs include Mint Mobile, Boost Infinite, and Visible.

Why is this important to you?

Understanding MVNOS is important because it means you can sign up for service on an MVNO and get the exact same coverage as one of the major carriers. Whichever major carrier the MVNO has an agreement with is the underlying network you will use for coverage.

MVNOs can also save you a LOT of money, too, because they have more affordable plans.

In addition to negotiating low wholesale rates for network access from the major carriers, MVNOs also use other cost-saving strategies such as operating online only to pass additional savings on to consumers.

Would you save money by signing up for an MVNO?

How are the Coverage Scores calculated?

The Coverage Scores are calculated for each of the carriers by looking at three key metrics:

  1. Coverage
  2. Data Speeds
  3. Reliability

Coverage

The Coverage Score is on a scale from 0 to 10.

To calculate the coverage score, we look at two key metrics: 1) the total area covered and 2) the tower density.

The total area covered comes from the signal strength data from the FCC. Any area that has signal is counted toward the total the total coverage area. A higher coverage area means a higher score. A lower coverage area means a lower score.

The tower density metric is also calculated using the FCC signal strength data. We estimate a carrier's tower density by looking at how many areas have high signal strength compared to low signal strength. Lots of areas with great signal indicate a higher tower density, and thus a higher score.

Data Speeds

The Data Speeds score is on a scale from 0 to 10.

We calculate the score by looking at a carrier's median download and upload speeds in a given area. Faster speeds means getting a higher score. We weigh the median download speed at 70% of the total score and the median upload speed at 30% of the total score.

To score a perfect 10/10, a carrier would need to get median speeds of 100Mbps download and 20Mbps upload.

Reliability

The Reliability Score is on a scale from 0 to 10. The goal for the Reliability Score is to estimate how likely you'll have a usable connection when you have service.

To calculate the Reliability score, we look at the bottom 10%, 5% and 1% of data speeds in a given area. The download speeds are weighted at 50% of the score. Upload speeds are weighted at 20% of the score.

We also look at latency to calculate the Reliability Score.

Latency is a measurement of how long it takes a data packet to travel from the sender to the receiver. You can think of latency as answering the question, "how much delay is there in the network?"

If there is high latency (30ms to 100ms), it takes a long time for data packets to be sent and received by your phone. Your connection may feel slow or "laggy."

If there is low latency (under 30ms), your connection will feel fast and responsive.

Latency is weighted at 30% of the Reliability Score.

Overall Score

The overall score looks at the Coverage, Data Speeds, and Reliability Scores and weighs them as follows:

  • Coverage Score: 70%
  • Reliability Score: 23%
  • Data Speeds Score: 7%

Where does CoverageMap.com get its coverage and speed data from?

CoverageMap.com gets different data from different sources.

The overall coverage and signal strength data comes from the FCC's mobile broadband map.

The information about data speeds and network performance comes from community members contributing speed test results to our crowd-sourced coverage map.
