UScellular is now T-Mobile: what that means for roaming, unlocking and your plan

T-Mobile bought UScellular’s wireless business on August 1, 2025. Every uscellular.com page, including its plans, roaming and unlock pages, now redirects to t-mobile.com, and UScellular prepaid customers “can no longer renew service.” If you’re a UScellular customer, your roaming and unlocking now run through T-Mobile. I’m not a UScellular or T-Mobile customer. This is T-Mobile’s own pages, read on October 3, 2026, and UScellular’s old pages as saved by the Internet Archive, marked as such wherever they’re used.

What happened to UScellular?

T-Mobile’s closing announcement says it “closed its acquisition of UScellular’s wireless operations” on August 1, 2025. T-Mobile took the customers, most of the stores and some spectrum. The towers and the rest of the spectrum stayed with the old company, renamed Array Digital Infrastructure.

At closing, T-Mobile said UScellular customers would “remain on current plans for now” and could later choose T-Mobile plans, with integration taking “about two years from close,” and that “the UScellular brand will transition in phases to T-Mobile.”

Today the transition is visible on the web: uscellular.com, its plans page and its support pages all send you to t-mobile.com. Copies saved by the Internet Archive show the UScellular home page still loading, with a “Joining T-Mobile” notice, in late August 2026, and redirecting by September 10, 2026.

What should a UScellular customer do now?

T-Mobile’s page for UScellular customers is the place to start. It answers “I got a text that said my account was moved to T-Mobile. What do I do now?” and covers what carries over: your number and voicemail move, your old login doesn’t, and Call Guardian becomes Scam Shield.

• Prepaid: T-Mobile’s prepaid welcome page says UScellular prepaid service can no longer be renewed, and offers a move to T-Mobile prepaid keeping your number.
• Business accounts: T-Mobile says migration to T-Mobile “is now underway” on its business page.
• New accounts: UScellular doesn’t sell plans any more. Its plans page redirects to T-Mobile’s, so if you’re shopping, you’re shopping T-Mobile or a carrier on another network. T-Mobile cost per line has what 1 to 6 lines cost with the fees.

How does international roaming work for UScellular customers?

T-Mobile’s page for UScellular customers says: “You can continue using your phone while traveling internationally, including in Canada and Mexico, based on your plan’s included features,” and that T-Mobile “offers simple add-ons you can add anytime.” It doesn’t list what each old UScellular plan includes.

If you’ve moved to a T-Mobile plan, roaming follows that plan. Experience Beyond includes 15 GB of high-speed data in 215+ countries and destinations, Experience More includes 5 GB, and Essentials includes texting abroad, with data by pass. T-Mobile abroad has the detail, and the roaming comparison prices a trip on every carrier.

For accounts still on UScellular’s own terms, the last archived roaming page (May 2026) said UScellular would “automatically add a $15 Daily Pass” when you travel, with Mexico and Canada at $5 a day, and that calls, texts and data were included on its Everyday and Even Better plans. That’s an archived page, not a current one. Check your account before a trip.

Does Verizon roam on UScellular?

Not that any company page says. UScellular’s 2024 annual report says it “has entered into roaming agreements with national carriers” without naming them. T-Mobile’s closing announcement says UScellular customers would move beyond limited roaming, “starting with reciprocal roaming” with T-Mobile customers. Separately, Array sold some spectrum licenses to Verizon in June 2026, which is a sale of spectrum, not a roaming deal.

How do you unlock a UScellular phone?

T-Mobile’s unlock policy says: “Current UScellular customers, please review the UScellular Device Unlocking Policies.” That link now redirects to a T-Mobile legal page, so the policy isn’t published where T-Mobile points.

The last archived copy of UScellular’s unlocking policy (June 2026) said:

• paid-off postpaid phones unlock after 40 days, and UScellular “will automatically unlock your postpaid device if your account is in good standing”;
• phones on an installment plan stay locked until it’s paid off, then 40 days;
• prepaid iPhones after 40 days, prepaid Android phones right away;
• former postpaid customers can unlock once they’ve paid everything owed.

Phones sold by T-Mobile follow T-Mobile’s rule. Postpaid: active at least 40 days on the line and paid in full, then unlocked automatically within two business days. Prepaid: 365 days since activation, or sooner with more than $100 in refills. Phone unlock policies by carrier has every carrier’s rules side by side.

What this page doesn’t know

Whether every UScellular account has finished moving to T-Mobile, what an old UScellular plan includes abroad today, and whether UScellular’s daily passes still exist are not on any page read for this article. T-Mobile’s page for UScellular customers, or its support line, is where to confirm them.
