AT&T Service Plans and Coverage Review

AT&T is one of the largest wireless service providers in the United States, offering a variety of service plans and extensive coverage across the country. Here is a review of AT&T's service plans and coverage:

Plans: AT&T offers a range of postpaid (contract) and prepaid plans to suit different needs. These plans typically include unlimited talk and text, with varying data allowances and speeds. Customers can choose from different plan options based on their usage requirements and budget.

Coverage: AT&T provides nationwide coverage across the United States, including both urban and rural areas. Their network covers a significant portion of the country, offering reliable connectivity in many locations.  AT&T operates on a combination of 3G, 4G LTE, and 5G networks, with 5G being the latest generation of wireless technology. The coverage and speeds offered by AT&T's networks have improved over the years, but they can still vary depending on factors such as signal strength, network congestion, and the type of device you're using.  

5G Network: AT&T has been investing in the deployment of 5G technology. They offer 5G coverage in select cities and continue to expand their network. It's important to note that 5G coverage may vary depending on your location and device compatibility.  AT&T's 5G network utilizes both low-band and high-band frequencies to provide broad coverage and faster speeds. AT&T's low-band 5G, also known as 5G Evolution, operates on sub-6 GHz frequencies, offering enhanced coverage compared to higher-frequency bands. This enables better penetration through buildings and obstacles. However, the speeds of low-band 5G may not be significantly faster than 4G LTE in some cases.

AT&T's network covers about 68% of the United States. This is 2% less than Verizon and 6% more than T-Mobile. AT&T has solid coverage in major cities, but not in rural areas. AT&T has the second-most 4G LTE coverage and the second-most 5G coverage of the major carriers. AT&T has the best latency. 

AT&T also deploys high-band 5G, commonly referred to as mmWave, in select areas. mmWave technology delivers extremely high speeds and low latency but has a shorter range and is more susceptible to obstructions like buildings and trees. Consequently, its coverage is typically limited to densely populated urban areas. In urban and suburban areas, AT&T generally offers good coverage and fast data speeds. 

The 5G network rollout is an ongoing process, and coverage availability and speeds may vary depending on your location. For the most up-to-date information on AT&T's 5G network and its coverage in your area, it is recommended to visit AT&T's official website or contact their customer support.

Unlimited Plans: AT&T offers unlimited data plans that provide unlimited talk, text, and data usage. These plans may have different data deprioritization thresholds, meaning that after a certain threshold of data usage, speeds may be temporarily reduced during times of network congestion.

Shared Data Plans: AT&T provides shared data plans, where multiple lines can share a pool of data. This can be a cost-effective option for families or groups with multiple lines.

Device Selection: AT&T offers a wide selection of smartphones and other devices for purchase. Customers can choose from flagship devices, mid-range options, and budget-friendly devices. They also support Bring Your Own Device (BYOD) programs, allowing customers to use their own compatible devices on the network.

Customer Service: AT&T has customer service channels available, including phone support, online chat, and in-store assistance at AT&T retail locations.

How to check your signal strength: You can check your AT&T signal strength by navigating to http://att.manager or http://192.168.1.1 from a connected device. The LTE icon will be displayed in the top right corner of the AT&T manager site when connected to 4G LTE. The Signal Bars display the connection strength.

How to Fix Your Apartment Cell Phone Dead Zone

If you're experiencing a cell phone dead zone specifically in your apartment, here are some steps you can take to try and improve the situation:

UMA Phone + Wi-Fi = Home Cell Coverage

Unlicensed Mobile Access (UMA) provides access to cellular mobile voice and data services over unlicensed spectrum technologies, such Bluetooth or Wi-Fi (802.11). A UMA phone will use a cellular networks (GSM, CDMA, etc.) when out and about, and automatically switch to a UMA-enabled Bluetooth or Wi-Fi local network when in range, such as at home or in the office. UMA technology is the 3GPP global standard for fixed-mobile convergence. UMA enables secure, scalable access to mobile voice, data and IMS services over broadband IP access networks. By deploying UMA technology, mobile operators can deliver a number of compelling fixed-mobile convergence services. The most well-known applications of UMA include dual-mode cellular/Wi-Fi handsets and 3G femtocells access points.

Leading operators around the world have embraced UMA technology as the foundation for their fixed-mobile convergence strategy, including Orange/France Telecom, British Telecom, T-Mobile US, TeliaSonera, Netcom, Saunalahti and Cincinnati Bell.

Improving coverage in areas where cellular signals are weak is an important issue for many organizations. UMA extends coverage to the workplace without forcing employees to change the way they use their cell phones. The only difference is that the phone will switch to Wi-Fi when it loses cellular coverage. To improve coverage with UMA, an organization sets up Wi-Fi access points in areas with poor cellular coverage to overcome coverage gaps and call dead zones. Companies with state-of-the-art, centrally managed wireless LANs (WLAN) can make a global configuration change to enable Wi-Fi UMA access from any location.

UMA-enabled Dual-Mode Wi-Fi Handsets: By far the most well-known UMA service is dual-mode cellular/Wi-Fi handsets (DMH), which enables operators to provide high-performance, low-cost mobile services to subscribers when in range of a home, office or public Wi-Fi network. With a UMA-enabled dual-mode Wi-Fi handset, subscribers can automatically roam and handover between cellular and Wi-Fi access, receiving a consistent set of services as they transition between networks.

UMA-enabled Femtocells: UMA-enabled femtocells represent a growing UMA service opportunity. The wireless industry has been searching for low-cost licensed indoor coverage solutions since the beginning of mobile networks. Unfortunately, the bulk of this opportunity (i.e. residential environments) has been beyond the addressable market for cost and operational reasons. To be successful, a residential licensed access point (i.e. femtocell) deployment must include low-cost femtocells (under €150), a reasonable approach for managing RF interference, and a standard, scalable, IP-based approach for core network integration.
UMA Today publishes the UMA Today Magazine, maintains the website, hosts Webinars and is involved in other industry activity to promote UMA technology. For more information, please visit
