On paper, T-Mobile had a good quarter. Profit jumped, revenue per account climbed, and the company nudged parts of its full-year outlook higher. Look one layer down, though, and the loyalty picture is less comfortable. More accounts are leaving, fewer are joining, and the reasons are mostly things T-Mobile did to its own plans.
Here is what the Q3 2026 numbers say, what changed on the pricing side, and what it could mean for anyone paying a T-Mobile bill.
The numbers behind the loyalty slide
| Metric (Q3 2026) | Q3 2026 | Q3 2025 |
|---|---|---|
| Postpaid account churn | 1.09% | 0.97% |
| Postpaid net account additions | 274,000 | 396,000 |
| Postpaid ARPA (revenue per account) | $155.73 | $149.44 |
Put plainly, churn is up by 0.12 percentage points, and net account additions fell by roughly 31%. At the same time, each account is paying more: ARPA rose about 4%. That combination is the heart of the story. T-Mobile is earning more from the customers who stay while losing ground on keeping them.
The company reported its results on 28 October. Net income came in around $3.5 billion, up 27%, with diluted EPS of $3.22. Service revenue was $19.4 billion, up 6%. Management also lifted its full-year profit and cash-flow guidance slightly and now expects about one million net postpaid account additions for 2026.
What changed: a timeline of 2026 plan moves
| When | What changed |
|---|---|
| April 2026 | Fiber plans refreshed with lower prices, but voice-line discounts and the five-year price guarantee were dropped from those offers |
| June 2026 | 5G home internet plans rose by $5 and gained speed limits; several legacy wireless plans were phased out |
| July 2026 | The KickBack discount ended; it had paid $10 per line per month to customers who kept data use under 2GB |
None of these moves is shocking on its own. Carriers adjust plans all the time. But stacked together over a few months, they gave customers several different reasons to look at their bill and ask whether it still made sense. Some customers face increases of up to $6 per line, which works out to $72 a year for one line and $288 for a family of four.
T-Mobile's side of the story
On the earnings call, CFO Peter Osvaldik described the churn as in line with what the company expected. He tied the rise in phone churn to the June decision to retire legacy plans and called it a "couple-quarter impact," adding that the effect in Q4 should be much more muted.
He also pointed to the mix of accounts. Broadband-only and fiber-only accounts tend to churn at higher rates than phone accounts, and they now make up a bigger share of the base. The UScellular acquisition adds to that effect. Looking ahead, he said overall churn would likely tick up in Q4 anyway, because the holiday season is usually a higher-churn quarter.
One more detail worth noting: T-Mobile now leads its reporting with account-based metrics such as net account additions, account churn and ARPA, rather than the postpaid phone subscriber numbers it used to headline. That is a legitimate way to report a business that sells phones, home internet and fiber together, but it makes year-to-year and carrier-to-carrier comparisons harder. The release did not give postpaid phone net additions or phone churn.
Rivals are selling bundles, and customers are listening
The competitive backdrop matters as much as T-Mobile's own choices. AT&T launched a plan in March that pairs wireless with one-gig fiber for $90 a month. Verizon followed in June with a wireless-plus-home-internet bundle at $70 a month. On the cable side, Comcast added 368,000 Xfinity wireless customers in Q3, and Spectrum added 406,000 in its previous quarterly report, helped by free or heavily discounted mobile lines bundled with home internet.
One survey cited in coverage found that 80% of Americans see bundled broadband and wireless as more cost-effective. If that instinct holds, a carrier that raises prices while rivals wrap everything into one cheaper bill is going to feel it in churn.
A reporter's take
I have covered enough earnings seasons to be wary of any quarter that looks great in the headline and awkward in the footnotes. This is one of those quarters. Profit up 27% and churn up at the same time is not a contradiction. It is what happens when a company squeezes more out of its base, and the base notices.
The risk for T-Mobile is not this quarter. It is the habit. For years the carrier built its brand on being the friendly challenger, the one that did away with contracts and gave things away. Cutting the KickBack discount and trimming perks on legacy plans may look fine on a spreadsheet, but it chips away at that goodwill, and goodwill is hard to rebuild once customers start comparing bills line by line.
There is also a fair counter-argument. Account churn of 1.09% is still low by most industries' standards, and management has a reasonable explanation: a one-time plan clean-up and a base that is shifting toward broadband-only accounts. If Q4 and Q1 show churn easing, this will look like a bump. If not, the "significant turn" in loyalty will turn out to be more than a one-quarter story.
One caution on comparisons: some coverage sets T-Mobile's 1.09% next to rivals' churn figures of roughly 0.9%. Since T-Mobile now headlines account churn, that may not be a like-for-like comparison, so I would treat it as a rough guide rather than a scoreboard.
What T-Mobile customers can do now
If you are on T-Mobile, spend ten minutes on your latest bill. Check whether your plan, fees or discounts changed in the past few months. Then compare it against bundles from AT&T, Verizon and the cable carriers, and look at discount options such as Mint Mobile, which T-Mobile owns. Before you switch, it is also worth calling T-Mobile and asking about retention offers. Carriers often have better pricing than the one on the website for people who say they are thinking of leaving.
Frequently asked questions
What happened to T-Mobile customer loyalty in Q3 2026?
T-Mobile's postpaid account churn rose to 1.09%, up from 0.97% a year earlier, while net postpaid account additions fell to 274,000 from 396,000.
Why are T-Mobile customers leaving?
Reports point to a run of 2026 changes: reduced discounts on fiber plans in April, a $5 rise and speed limits on 5G home internet plans in June, the phase-out of several legacy wireless plans, and the end of the KickBack discount in July. The CFO also cited the growing share of broadband-only accounts and the UScellular acquisition.
What is churn?
Churn is the percentage of customers or accounts a company loses in a given period. A higher churn rate means more people are cancelling or switching to another provider.
Is T-Mobile still making money?
Yes. In Q3 2026 T-Mobile reported net income of about $3.5 billion, up 27%, with diluted EPS of $3.22, and it raised parts of its full-year guidance.
Will T-Mobile churn get worse in Q4?
The CFO said overall churn is expected to rise in Q4 because the holiday season is usually a higher-churn quarter, though he expects the impact of the legacy plan changes to be much more muted.
What should T-Mobile customers do now?
Check your latest bill for plan or fee changes, compare your price against competitors' bundles and discount carriers, and ask T-Mobile about retention offers before switching.
The bottom line
T-Mobile is still a profitable, growing company, and its explanation for the churn bump is plausible. But the numbers show the cost of a year spent trimming perks and raising prices while rivals sold cheaper bundles. The next two quarters will show whether this was a clean-up hiccup or the start of a real loyalty problem.
