Speed Comparison

When it comes to raw download speeds, AT&T offers 5,000 Mbps (Fiber) / 100 Mbps (DSL) at the top end, while T-Mobile reaches 245 Mbps. These maximum speeds tell part of the story, but the typical speeds you will experience in your home depend on your plan tier, network congestion in your area, and whether you connect via Wi-Fi or Ethernet. Both providers advertise their peak speeds prominently, but the entry-level plans are what most subscribers actually sign up for, so it is worth comparing the base tiers as well as the premium options.

Upload speeds are an increasingly important factor for remote workers, content creators, and anyone who regularly video conferences. AT&T provides upload speeds up to 5,000 Mbps (Fiber) / 20 Mbps (DSL), compared to T-Mobile's 33 Mbps. Fixed wireless 5G upload speeds can vary more than wired connections since they depend on signal strength, tower distance, and network congestion. Wired connections, whether fiber, cable, or DSL, typically deliver more consistent upload performance throughout the day. If steady upload speed matters for your daily workflow, keep this distinction in mind.

Latency, often called ping time, measures how quickly data travels between your device and the server. AT&T delivers typical latency of 5-15 ms (Fiber) / 20-45 ms (DSL), while T-Mobile comes in at 25-50 ms. For most everyday internet activities like web browsing, streaming video, and social media, both latency ranges are perfectly acceptable. However, competitive online gamers and traders who need the absolute lowest latency will prefer whichever provider offers fiber-optic service, as fiber consistently delivers the lowest and most stable ping times of any consumer internet technology available today.

Data caps determine how much you can download and upload each month before facing throttling or overage charges. AT&T has the following data cap policy: None on Fiber, 1 TB on DSL (waived w/ unlimited plan). Meanwhile, T-Mobile's policy is: None (truly unlimited). In an era of 4K streaming, cloud gaming, smart home devices, and work-from-home demands, a household can easily consume hundreds of gigabytes per month. Unlimited data is increasingly important, and providers that enforce caps may penalize heavy users through throttling, reduced speeds, or extra fees. Check the fine print of any plan you are considering to understand exactly how data limits apply and whether there are options to upgrade to unlimited service.

Pricing Comparison

AT&T plans start at $55 per month and go up to 180/mo for its highest speed tier. T-Mobile pricing ranges from $40 per month to 60/mo at the top end. When comparing these prices, it is important to look beyond the headline number and consider what you actually get at each price point. The cheapest plan from one provider may deliver significantly more speed than the entry-level offering from the other, making the per-megabit value quite different from what the sticker price suggests.

Contract terms and promotional pricing play a major role in the true cost of internet service. Some providers offer attractive introductory rates that increase substantially after 12 or 24 months, while others maintain consistent pricing throughout your subscription. Equipment fees are another hidden cost to watch for. Router rental fees typically range from $10 to $15 per month, which adds $120 to $180 annually to your bill. Both AT&T and T-Mobile may offer options to use your own compatible router, potentially saving you money over the life of your subscription.

Installation costs are worth factoring into your budget as well. Fiber installation can sometimes be free during promotional periods but may cost $50 to $100 or more at other times. Self-installation kits are often available for simpler setups, reducing or eliminating the installation fee entirely. Look for seasonal promotions, bundle discounts if you also need TV or phone service, and special offers for new customers. Both providers typically offer their best deals to new subscribers, so it is worth checking their websites or calling to ask about current promotions before committing.

When calculating the total cost of ownership over a two-year period, consider the monthly rate, any rate increases after the promotional period ends, equipment rental fees, installation charges, and potential early termination fees if the provider requires a contract. A plan that appears cheaper upfront may end up costing more over time if the price jumps significantly after the introductory period. Conversely, a slightly more expensive plan with price-lock guarantees and no contracts may deliver better long-term value and peace of mind for budget-conscious households.

Coverage and Availability

AT&T offers fiber service (AT&T Fiber) in 21 states, primarily in the South and Midwest, covering about 19 million locations. Its legacy DSL network extends to millions more addresses across its traditional service territory. Major metros include Dallas, Houston, Atlanta, Chicago, Miami, and Los Angeles.

T-Mobile 5G Home Internet is available across large portions of the United States, leveraging T-Mobile's extensive 5G network that covers over 300 million people. Service is available in both urban and suburban areas, with expanding rural coverage. However, availability at a specific address depends on local network capacity and tower proximity.

T-Mobile 5G Home Internet availability is determined by local network capacity rather than physical infrastructure to your home, which means it can be available in areas where wired providers have not yet built out their networks. However, T-Mobile may also restrict sign-ups in areas where their towers are at capacity. The best approach is to check both providers' websites with your exact address, as availability can vary block by block in some markets. In areas where both services are available, you may benefit from testing T-Mobile's service since many plans include a trial period or no-contract terms that let you switch without penalty if the service does not meet your needs.

Customer Satisfaction

AT&T has improved its customer satisfaction significantly since expanding its fiber network. According to the American Customer Satisfaction Index, AT&T Fiber consistently scores higher than its DSL offerings. J.D. Power surveys generally place AT&T in the upper tier among large ISPs, though customer experiences can vary between fiber and DSL territories.

T-Mobile has earned strong customer satisfaction ratings for its home internet service since launching in 2021. The company's transparent pricing, lack of contracts, and simple setup process have resonated well with consumers. Its J.D. Power scores for fixed wireless service have been competitive with traditional cable providers.

When evaluating customer satisfaction, it is important to consider that experiences can vary significantly by location, technology type, and individual expectations. A customer on a fiber connection will almost always report higher satisfaction than one on DSL or satellite, regardless of the provider. Online reviews tend to skew negative since dissatisfied customers are more motivated to leave feedback, so industry surveys from organizations like J.D. Power and the ACSI provide a more balanced picture. We recommend checking recent reviews specific to your area, as service quality can differ meaningfully between regions even within the same provider's network.

Which Provider Should You Choose?

Choose AT&T Internet if: You want the fastest possible speeds for a household with many devices, you need reliable low-latency connections for gaming or video conferencing, you are in an area with AT&T Fiber availability, or you want a proven wired connection that delivers consistent performance regardless of weather conditions or network congestion. AT&T Fiber's symmetric speeds up to 5 Gbps are ideal for tech-heavy households.

Choose T-Mobile 5G Home Internet if: You prioritize affordability and simplicity, you dislike contracts and want the freedom to cancel anytime, you are in an area without wired broadband options, you want straightforward pricing with no hidden fees, or your internet needs are moderate (streaming, browsing, video calls). T-Mobile's $40-60 per month plans offer exceptional value for the everyday internet user.

How to Check Availability

The fastest way to determine whether AT&T or T-Mobile is available at your home is to check directly with each provider. Both offer online address-lookup tools on their websites where you can enter your street address and instantly see which plans and speeds are available. You can also call their dedicated sales lines for personalized assistance. Representatives can check availability, explain current promotions, and walk you through the sign-up process. If you are moving to a new address, checking availability before you finalize your housing decision can save you from settling into a home with limited connectivity.

If neither provider is available at your address, consider checking other options in your area. Fixed wireless providers like T-Mobile and Verizon 5G Home Internet are expanding rapidly, and local fiber providers may serve your specific neighborhood even if larger national brands do not.
