As anyone who lives there knows, Indiana is a very flat state. That’s good news for cell phone coverage, since there’s a minimum of natural barriers to getting a good signal.
The three majors dominate the coverage landscape in Indiana: AT&T, Verizon, and T-Mobile have all built out impressively wide-ranging 4G and 5G networks in the state. By the numbers, Verizon delivers the most 4G coverage (its network spans an incredible 97% of Indiana’s total land area), while AT&T offers the most 5G coverage (74%).
There are some nuances to coverage in Indiana, so you’ll want to read on—and check out the coverage maps—to figure out which of these carriers actually gives you the best signal in the places you live, work, and play.
Verizon started building out its network in Indiana very early in the history of cellular technology, and it’s only gotten more ubiquitous through the years. At present, the carrier offers the most 4G LTE coverage in the state, and a small but growing 5G network.
Verizon delivers the most 4G coverage in Indiana, blanketing an amazing 97% of it with its network. Translation: if you have Verizon, you’ll be able to get a signal pretty much anywhere you go, from the shores of Lake Michigan in the north to the Kentucky border in the south, and everywhere in between.
Verizon’s 5G network covers 28% of Indiana, trailing both AT&T (73%) and T-Mobile (65%). While this may not sound like much, note that all of Indiana’s major towns and cities are covered by Verizon 5G, including Indianapolis, Fort Wayne, Evansville, South Bend, and Bloomington.
Also, Verizon may in fact offer the fastest 5G speeds where you live. That’s because much of Verizon’s 5G network is made up of its enhanced 5G Ultra-Wideband network, which delivers super-fast speeds and low latency times.
AT&T offers the most combined 4G and 5G coverage in Indiana, as both of its networks blanket the majority of the state.
AT&T delivers the second-most 4G coverage in Indiana, with its network spreading to an impressive 95% of the state (just a tiny bit less than Verizon). Rest assured that you’re likely to have an AT&T 4G signal almost regardless of where you go in Indiana.
AT&T offers far and away the most 5G coverage in Indiana, with 74% of the state’s 35,867 square miles covered. This is good news if you’re signed up with AT&T, since 5G delivers the fastest cellular speeds.
Plus, a good portion of AT&T’s 5G coverage is made up of its enhanced5G+ spectrum, which delivers even faster speeds, lower latency times, and better reliability.
While T-Mobile doesn’t win the coverage statistics battle with competitors AT&T and Verizon in Indiana, the carrier nonetheless delivers excellent overall 4G and 5G signal availability in the state.
T-Mobile’s 4G network covers an excellent 76% of Indiana, less than both Verizon (97%) and AT&T (95%). However, T-Mobile’s 4G is present in all of the state’s foremost cities and towns; if you live in one of these areas, rest assured that you should have no problem connecting to T-Mobile.
T-Mobile offers great 5G coverage in Indiana, as its network covers 65% of the state. Much of this 5G coverage includes the carrier’s 5G Ultra Capacity spectrum, which offers super-fast speeds and superior reliability.
Note that your carrier choices aren’t limited to the majors in Indiana. 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 some popular MVNOs, and the networks they operate on:
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.
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:
