AT&T Expands Build-A-Plan to Offer Flexible Wireless with Integrated Home Internet

AT&T is expanding its Build-A-Plan service to include home internet, letting customers bundle wireless and broadband in a single sign-up flow starting at $70 per month, according to AT&T Newsroom. The new combined package pairs unlimited wireless at $35 per month with home internet — either AT&T Fiber or AT&T Internet Air — for another $35 per month.
The expanded plan goes live July 7, 2026, Investing.com reported. It builds on the original Build-A-Plan launch in May 2026, which started at $15 per month for a single wireless line with just 1GB of data.
AT&T first announced Build-A-Plan on May 21, 2026, according to PR Newswire. The base price was $15 per month for one line with 1GB of data. Customers could also choose 5GB or 15GB tiers. Data slows to 128 Kbps once the cap is hit, PCMag noted. The plan went live for consumers on May 27 and was limited to new single-line customers.
AT&T then streamlined its home internet options on June 7, introducing four simple fiber speed tiers to make bundling easier, AT&T Newsroom reported. Today's announcement connects those two moves into one unified customer experience. More than 50% of surveyed customers said they wanted to add wireless and home internet in a single flow, according to AT&T Newsroom.
The push is a direct response to competition. Cable companies like Comcast and Charter have pulled wireless customers away by bundling mobile service with home broadband. Verizon's $20 billion acquisition of Frontier in January 2026 expanded its fiber footprint and put more pressure on AT&T, TheStreet reported. AT&T added 584,000 new internet customers in Q1 2026, outpacing Verizon's 341,000 in the same period.
AT&T CEO John Stankey has made convergence — combining wireless and home internet under one provider — a top priority to reduce customer churn, according to TheStreet. Executive VP Jenifer Robertson said, "Customers told us they want connectivity that works together seamlessly and the flexibility to choose what fits their lives," Investing.com reported.
Not everyone is impressed. PCMag called the data-cap model "retro," comparing it to old "bucket" plans that caused bill anxiety when users went over their limits. The plan is also online-only and requires an unlocked, eSIM-capable phone. That could shut out older customers or anyone with older hardware, CNET noted.
MobileX CEO Peter Adderton claimed on social media that AT&T is copying his company's AI-driven customization model, which smaller carriers pioneered years ago, Fierce Network reported. Some analysts also note that the best deals go to new customers who bring their own devices, potentially leaving long-term AT&T subscribers stuck on older, pricier plans.
Industry analyst Roger Entner of Recon Analytics praised the approach, saying "For too long postpaid 1-line prices made no sense," according to Broadband Breakfast. He added that AT&T's transparent monthly pricing puts real pressure on cable operators who typically offer free lines for a short period rather than sustained, predictable costs, Light Reading reported.
AT&T currently has a market cap of $151.3 billion, Investing.com noted. If customers who start at the $15 base tier eventually scale up to the $70 bundle, the company's average revenue per user could rise significantly. AT&T Internet Air also gives the plan reach beyond fiber zones, serving rural customers through 5G fixed wireless where fiber lines don't yet run.
