AT&T OneConnect: one flat price for fiber and wireless
AT&T's newest plan folds 1 Gig fiber and unlimited 5G into a single bill from $90/mo. It's the first bundle that removes per-line math entirely — if you clear two hard eligibility gates.
If AT&T Fiber reaches your address and you have three or more phones, OneConnect is the best-value bundle any national carrier currently sells — Family at $225/mo for 1 Gig fiber and up to ten lines undercuts buying the same pieces separately by well over $100. Solo households get the weakest deal: $90 buys one line and fiber that costs about $80 on its own.
The three tiers, side by side
What the flat price actually removes
Every other carrier prices wireless per line and internet separately, which means the answer to "what will this cost me?" depends on a line count, a promo window, an equipment fee and a bundle discount that all move independently. OneConnect collapses that into one number per household size. Adding a tablet or a smartwatch changes nothing on the bill. Neither does a fifth phone on the Family tier. That's a real product decision, not just marketing — the plan is priced for the household rather than the SIM.
The wireless side is genuinely unlimited talk, text and high-speed data in and between the U.S., Canada and Mexico, which is normally a premium-tier feature. Hotspot data is the one deliberate omission: it's a $15/mo per-line add-on for 50GB, after which speeds drop to about 128Kbps. If you tether for work, budget for that line item rather than assuming the flat price covers it.
Where it's a bargain — and where it isn't
Family is the tier that makes OneConnect worth a headline. Ten phones plus 1 Gig fiber for $225 works out to roughly $14.50 per line once you set aside the $80-ish that fiber alone would cost. Nothing else on the market gets close at that line count, and the device ceiling of 20 is generous enough that a house full of tablets and watches never bumps into it.
Duo at $120 is solid: two lines and fiber for $40 more than fiber by itself. Individual at $90 is the tier to think twice about. You're paying about $10 over the standalone fiber price for a single unlimited line, which sounds excellent until you notice you're also accepting a 4-device cap and losing the flexibility to shop your wireless separately. It's fine value; it just isn't the transformative deal the tier structure implies.
The savings curve is also less smooth than it looks. Carriers already discount heavily at four and five lines, so a five-phone household saves less by switching to Family than a two-phone household saves by switching to Duo, in proportional terms. The gap widens again past six lines, where per-line pricing elsewhere stops falling and OneConnect's flat $225 doesn't move. We ran the numbers line by line here.
The $200 reward card is not $200 off
The signup promo requires two completed payments and arrives within about ten weeks of fiber installation, as a prepaid card. That's real money, but it's roughly $17/mo of value spread across year one, delivered late, in a form you can't apply to the bill. Price the plan on $90, $120 or $225 and treat the card as a bonus that shows up in the fall.
What we'd want to see change
The device caps are the fine print most likely to bite. A Family household with ten phones has exactly ten slots left for every tablet, watch and connected device across the house — reachable in a family of five. Publishing that ceiling next to the price rather than four accordions down would be the single most honest change AT&T could make to this page.
We'd also like a fixed-wireless variant. Millions of households would take a OneConnect-style flat price with Internet Air as the home leg at a lower tier, and the eSIM-only requirement already means AT&T isn't chasing the low end of the handset market anyway.
Should you get it?
Check fiber availability first, then count your phones. Three or more lines with fiber at the door: switch, the math isn't close. Two lines: Duo is a good deal and the simplicity is worth something on its own. One line: compare it honestly against fiber plus a cheap prepaid or MVNO plan, which will usually come out lower even if it's more to manage.
Skip it if you tether constantly, if anyone in the house carries a locked or older phone, or if you rely on the streaming perks and phone-upgrade promos that OneConnect's flat price doesn't include. Simplicity is the product here — if you actually enjoy optimizing each piece, you can still beat it.
