While we’ve outlined cell phone coverage from the three major U.S. cell phone carriers, it’s important to know that you aren’t limited to these companies if you need cell phone service in Delaware. A variety of smaller carriers, or MVNOs, also operate in the state, allowing you to sign up for equivalent plans, with similar coverage, for less than you’d otherwise pay.
All of these carriers lease from the aforementioned major carrier networks to provide coverage to their customers. If you’re signed up with Spectrum Mobile, for example, you’ll have access to Verizon coverage, since the carrier runs on that network. Here are some popular MVNOs, and the networks they operate on:
Things to Know about Cell Phone Coverage
Cell Phone Coverage Speeds
When it comes to cell phone coverage, you don’t just need a cellular signal—you need that signal to provide adequate speed. That’s why it’s important to distinguish between 4G and 5G coverage in your area. In general, 5G provides faster speeds and greater reliability than 4G. However, that’s not always the case, as there may be instances when the speeds of these respective coverage types are actually quite similar.
How to Get the Best Cell Phone Coverage
There’s more to getting the best coverage than just signing up with the carrier that offers reliable service in the places you spend time. These include:
- Your phone: The newer and more cutting edge your device, the more likely you’ll be able to tap into the fastest speeds. Some older phones don’t have the built-in technology to connect to the fastest 5G bands, resulting in slower service. The newest 5G devices, like the Apple iPhone 16 or Samsung Galaxy S24 series don’t have this problem.
- Your software: It’s important to make sure your software is up to date, as an out-of-date operating system can translate to an inability to connect to the fastest network speeds.
- Your cell phone plan: Depending on the mobile plan you have, your data may experience deprioritization during times of network congestion. If this is consistently happening to you, it may be worth investigating whether you can sign up for a plan that includes more premium (i.e. un-deprioritized) data.
- Your location: Certain types of coverage, like high-band 5G, has difficulty penetrating solid materials, like concrete walls. As simple as it may sound, moving to an unobstructed location may help you connect to these fast networks more reliably.
