Verizon and T-Mobile come in a close second and third for 4G LTE coverage, with T-Mobile beating out its competitor for 5G access.

The maps confirm that AT&T provides the most robust 4G LTE coverage in Delaware. This is great news for residents of The Small Wonder.
Delaware is broadly covered by both 3G and 4G LTE technology. 3G is the network that some older phones run on, and the one newer 4G LTE-capable devices fall back to when unable to reach a primary network.
5G Coverage in Delaware
The future of wireless technology has arrived. All three major carriers have deployed their own versions of the latest in cellular technology, which promises blazing-fast speeds, ultra-upgraded bandwidth, and near-zero latency... in short, the best wireless performance ever seen.
Though T-Mobile is currently the nationwide 5G leader, AT&T pulls out an upset with a massive 51% coverage across Delaware. This is in large part because coverage stats account for both area and population density, and AT&T's 5G network is widespread in highly populated cities like Wilmington and Dover.
T-Mobile still has a respectable 5G presence in the state, offering 16.8% coverage. Verizon has yet to build any of its high-band 5G access points within Delaware, though the nation's 4G LTE leader has recently announced plans to deploy low-band 5G that may soon bring its network to The First State.
Big Carriers vs. Small Carriers in Delaware
Did you know that there are dozens of small carriers that run on the major networks, but charge a fraction of the price for service? These companies are known as Mobile Virtual Network Operators, MVNOs for short. MVNOs purchase network service from the major providers at wholesale prices, then pass the savings on to consumers.
If you're interested in Verizon's coverage, for example, but are looking for a better deal, Straight Talk Wireless, Twigby and Red Pocket are just a few of the smaller providers you'll want to check out.
