The UScellular customer service line is 1-888-944-9400. T-Mobile completed the purchase of the UScellular wireless business and its customers on 1 August 2025, and uscellular.com now redirects to t-mobile.com, so former UScellular accounts are serviced by T-Mobile, through its own support pages, its app and its stores, and that is where a bill, a device or a coverage question belongs. The listed company that remained kept the towers and most of the spectrum and renamed itself Array Digital Infrastructure, which sells to carriers rather than to consumers, so it is not a route for a personal account.

UScellular sold its wireless operations to T-Mobile in a deal announced in May 2024 and completed on 1 August 2025, which moved more than four million customers and part of the spectrum across to the buyer. What was left of the company kept most of its towers and spectrum and now trades as Array Digital Infrastructure. The UScellular brand is being retired in stages, and its website already points at T-Mobile. For a customer the practical effect is that the account, the bill and any device agreement now sit with T-Mobile, while the agreement you originally signed with UScellular is still the document to quote when you dispute something that was agreed before the handover.

A device installment balance agreed with UScellular does not disappear because the business changed hands: it is a payment agreement for the handset and it is serviced now alongside the rest of the account. Read that agreement for the number of payments, the amount outstanding and what happens if you leave, because leaving usually makes the remaining balance due at once. Compare the balance shown now against the last UScellular statement you hold, and query any difference in writing rather than by phone alone. Promotional bill credits that were paying the handset down are the item that most often stops early, so check whether those credits are still running month by month.

Bill credits that were paying down the handset stopped when the account moved? Raise it through our complaint process and our trained AI opens a case and keeps coaching you: what to quote from the original agreement, and how to escalate if nothing happens.

Unlock and port out requests for a former UScellular handset go to the carrier that now holds the account, because that is where both the device record and the line sit. Before you ask, check that the handset is paid off, that the account is in good standing and that any lock period in the original agreement has run its course, since those are the usual grounds for a refusal. A port out needs the account number and the transfer PIN from the carrier you are leaving, not from the one you are joining. Ask for any refusal in writing with the reason attached, keep the IMEI of the handset with your records, and remember that the federal communications regulator in the United States takes consumer complaints about carriers.

Nothing has been reported about UScellular here yet. Our research shows what typically goes wrong for customers of a regional carrier, and what tends to follow when one is absorbed into a larger network: indoor coverage patchier than the map suggested, bills jumping on activation, upgrade or prorated charges, promotional credits and rebate cards that never arrive or stop partway, device installment balances falling due on a switch, delays unlocking a handset or porting a number out, and store and phone support giving different answers.

Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of UScellular through emails, social media, paper complaint letters and other tools at our disposal.

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with UScellular can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
