AT&T Internet Air vs T-Mobile Home Internet: Prices

On their main plan cards, T-Mobile Rely starts below AT&T Internet Air before phone-bundle discounts. That is a starting comparison, not a guaranteed quote: both providers show conflicting prices elsewhere on their own sites. Check your address and the final order summary before choosing either service.

This AT&T Internet Air vs T-Mobile Home Internet comparison covers U.S. residential plans in USD, checked November 4, 2026. It compares official prices and terms, not hands-on speed tests. Both deliver internet to a home gateway over a cellular network. The practical question is whether the connection works in your house at a price you can keep paying.

AT&T Internet Air vs T-Mobile: monthly prices and fees

The table uses AT&T’s main Internet Air offer and T-Mobile’s primary plan cards and Broadband Facts labels. It does not assume you qualify for a phone bundle or a promotional reward.

These totals are multiplication, not annual prepaid deals. They exclude taxes, fees, one-time charges, credits and optional extras. Do not confuse the number in the last column with an amount due upfront, a guaranteed renewal price or your household’s complete bill.

The conflicting prices need checking. AT&T’s separate Internet Air FAQ says $60 after its stated AutoPay discount, rather than the main page’s $55 starting offer. T-Mobile’s same-page comparison table shows $35/$45/$55 with AutoPay and $30/$40/$50 with a voice line, while its main cards advertise a $20 voice-line discount. We could not establish one universally applicable lower offer from those conflicting displays.

T-Mobile’s AutoPay requires a bank account or debit card; otherwise add $10 monthly. Its gateway is included; disclosures list a $35 connection charge and $2.60 monthly recovery fee, with taxes and account-specific conditions. AT&T advertises an included All-Fi Hub and $0 self-setup. Get applicable fees and any waivers in your written quote.

Compare the whole bill before taking a bundle

If you already have an eligible phone line, request the matching internet quote from that carrier. If you would need to switch phone plans, compare the whole household bill. Saving $15 on internet is not a saving if the required phone service costs $25 more than you pay now.

Using only the main cards, Rely is $5 a month below Internet Air, or $60 across 12 months before fees. That small difference is easy for a connection charge or a different address quote to erase. For the tiers’ included extras, see our Rely, Amplified and All-In comparison.

Keep one-time rewards separate from the normal monthly bill. If your quote includes a reward, save its registration deadline and eligibility rules before ordering. Ask for the price after any credits end, and what happens to the internet discount if you cancel the phone line. A reward arriving later is not a reduction in every month’s charge.

T-Mobile’s five-year data-price guarantee excludes taxes, fees and some promotions. Do not read it as a promise that the entire household bill will stay unchanged.

Published speeds: compare the plan, not just the carrier

AT&T’s FAQ and T-Mobile’s expanded Broadband Facts labels publish these typical ranges. They are provider disclosures, not speeds measured for this article or guarantees for your address.

T-Mobile’s higher tiers have a higher published download range, but that does not prove they will beat AT&T in your living room. Indoor signal, tower capacity and evening demand can change the result. A phone showing strong 5G is a useful clue, not an eligibility check or a guarantee of gateway performance.

For video calls and photo backups, check uploads as well as downloads. For gaming, try the actual game and voice chat. A fast download does not rule out delays, disconnects or compatibility problems. Our guide to 5G home internet versus cable for gaming explains what to test before switching.

Unlimited data still has congestion rules

Both providers advertise unlimited data. That means you should not read their typical speed ranges as a promise of the same speed throughout the month.

AT&T discloses temporary slowdowns when the network is busy and, in rare usage-related congestion cases, a substantial speed reduction for at least 30 minutes. T-Mobile discloses lower speeds during congestion and further prioritization above 1.2 TB a month. The latter is not an automatic overage bill or service cutoff.

A family downloading large games, uploading camera footage or streaming on several TVs should test at the times it actually uses the connection. A quiet weekday-morning speed result will not answer whether dinner-time streaming works.

Gateway placement and the trial deadline matter

Follow the provider’s setup app to find a suitable gateway location. There are two connections to consider: the gateway’s cellular link to the network and its Wi-Fi link to your devices. Adding a mesh extender may help a distant bedroom; it cannot fix a weak cellular connection to the gateway. Wi-Fi 7 on an included router is not a promise of faster service from the tower.

T-Mobile’s 15-day Test Drive support page contains conflicting start-date wording. Its instructions say online and phone orders start when you receive the gateway’s shipping notification; retail orders start with activation and taking the device home. Its closing terms instead say to cancel within 15 days of service activation. Do not assume the clock starts when you unpack the box, or choose the later interpretation without confirmation.

Ask T-Mobile for your exact last eligible cancellation date, and plan around the earlier plausible deadline until it confirms otherwise. Eligible cancellation uses a bill credit, not an unconditional free month. Equipment deadlines also conflict: Test Drive support says 45 days after cancellation, while T-Mobile’s cancellation instructions require return within 14 days and warn of up to $370 plus tax for a late or missing return. Confirm your account’s deadline, return promptly and save the shipment tracking.

AT&T advertises no annual contract, but that is not the same as an unrestricted free trial. Confirm cancellation, service-charge and equipment-return terms before ordering. With either provider, keep the return receipt and do not cancel your current internet until the replacement meets your needs.

Which should you choose?

Price Rely first if you want the lower starting figure on the main cards, but let the confirmed quote decide the cost comparison. Consider a higher tier only when its speed range or included extras solve a need you actually have. Paying for the highest tier does not remove the need to test reception and evening performance.

Keep AT&T Internet Air on the shortlist if its actual quote is competitive or its gateway works more reliably where you can place it. If AT&T offers Fiber instead, compare that separately: Internet Air is not fiber service. Our AT&T Fiber versus Xfinity cost guide covers wired alternatives.

Before committing, save both Broadband Facts labels and order summaries. Test evening TV, a work call and your normal uploads during any eligible return window. Choose the connection that works in your home at the full price you will actually pay, not the one with the largest reward or highest speed printed in an ad.
