Best Cell Phone Plans in Claremont

Okay, now that you know the carrier with the best coverage and fastest data speeds in Claremont, CA, 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?

Frequently Asked Questions

What carrier has the best cell phone service in Claremont?

AT&T has the best overall cell phone service in Claremont. It offers the best balance between coverage, data speeds, and reliability.

What carrier has the most coverage in Claremont?

What carrier has the fastest speeds in Claremont?

AT&T has the fastest speeds in Claremont. Its median download speeds are 125.9 Mbps and its median upload speeds are 12.7 Mbps.

How is the Reliability Score calculated?

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.

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.
