AT&T Mobile

AT&T Mobility, also known as AT&T Wireless, is one of the major mobile carriers in the US. In fact, it is the oldest name in the phone business. It uses the world’s popular wireless phone technology, GSM (Global System for Mobile Communication), to deliver its services and is known for its extensive coverage. It is one of the best carriers offering high 4G download speeds, decent perks, and a strong 5G network.


  • Reliable network
  • Nationwide coverage
  • Wide range of plans


  • Expensive
  • Sparse 5G coverage

Which one is better, Spectrum Mobile or AT&T Mobile?


Although AT&T is known for its nationwide coverage, Spectrum Mobile uses Verizon’s network to deliver its services. And while Verizon and AT&T have an excellent range in metropolitan areas, the former’s 4G coverage in rural areas is better.

On the other hand, AT&T has slightly better 5G coverage, and Verizon’s wide-band 5G is faster. Hence, despite being an MVNO, Spectrum Mobile benefits from this extensive and robust network and is available in many parts of the country, including rural areas.


AT&T is a clear winner as it is available for every individual. You can join AT&T’s network with a digital or a physical SIM card.

On the other hand, Spectrum Mobile is only available to Spectrum Internet users. Moreover, the company charges an extra $20 monthly if you cancel your Spectrum Internet subscription. To qualify for Spectrum Mobile™ service, you must have the following:

  • Spectrum Internet service
  • Sign up for Auto Pay
  • Meet credit requirements

5G Access


Like other MVNOs, Spectrum Mobile also skimps on perks. However, you can receive benefits like unlimited talk and text, free Spectrum WiFi hotspots, and robust 5G speed. It also makes it convenient to switch over by allowing you to keep your existing phone number. Spectrum is transparent about its pricing; you don’t have to worry about unexpected charges.

AT&T, like other major carriers, offers numerous perks with its plans. It provides AT&T ActiveArmor with advanced mobile security, hotspot data, high-speed data, premium channels, and more.


You’ll never truly get high-speed unlimited data no matter which carrier you choose. Both Spectrum Mobile and AT&T enforce data caps on their plans and throttle your speed once you exceed the set limit.

Phones Offer

Spectrum BYOD allows you to bring your device. It covers all the latest phones from Apple, Google, and Samsung.

AT&T makes this process much easier with a wide variety of phones. This carrier allows you to bring nearly any phone and is also compatible with eSIM. It offers various promotions like free phones or buy-one and get-one-free.

Customer Service

Although it is hard to evaluate the customer service of Spectrum Mobile since major reviewers do not cover this service, we can get an idea through the rating of Spectrum Mobile App. We can conclude that the customers are satisfied with Spectrum Mobile as it has a 4.7 rating on the Apple store and a 4-star rating on Google Play Store.

AT&T is also known for its decent customer service, as it is typically ranked third among major providers. They also offer a variety of channels you can use to reach out to them.

Final Call

AT&T and Spectrum Mobile are prominent mobile carriers that offer plans with unique features. Both of them provide different benefits and have their strong points. In the end, if you are already a Spectrum Internet® user, we recommend using Spectrum Mobile since this service is more affordable than AT&T.
