Recently I have seen an upswing in angry calls and interaction from customers about this transition to T-Mobile. It is more so now because some of the pre transition sim swaps were found to not work. Customers have called the store and cussed out me and my associates over the merge and expressed how displeased they were with the information or the lack of information.

If you are one of these and are going to a store or calling the store to yell and complain about the fact that USCellular is now absorbed by T-Mobile, keep in mind the employees at you favorite USCellular store are more than likely to not have a job after July. When you yell at us about how you did not agree to this nor that you wanted it, we are there with you. The only difference is that you will have service after you are moved from USCellular, once we are moved we are unemployed.

his has been my PSA

How in the world does a company buy out another company and claim that the coverage will be even better because they are now using t-mobile towers and us cellular towers for coverage and the shit is 10x worse. Is everyone dealing with this?! Will it get better or should I switch to another service provider?

Tmobile locations are merging into US Cellular old locations
Most employees will not have jobs
All the employees from different TMO stores that are closing will take over the roles

So I am waiting for my account to switch over, I hate not having any guidance as to when it will happen, wishing there was a way to force it without canceling service and switching it myself early, that just won't work because of the payment plans on the phones. I would like some of the features of the tmobile service, like visual voicemail since mine stopped working with uscellular a while back and they were never able to help me get it working again, then they discontinued the service. Also looking forward to the tmobile parental controls. Anyone else in the same boat of waiting and waiting? Anyone know what the rhyme or reason is behind who switches when?

Should I do the Costco TMobile switch from AT&T?

I got the text that I was switched over to T-Mobile. I have an iPhone 13 Pro Max. Ever since then my battery drains twice as fast. Has anyone else experienced this?

We are a family owned business who uses US Cellular and are in need of additional equipment for the safety of our crew ASAP .Our Reps phone no longer works and Customer Service basically can’t help us or give us any direction due to the merger. Has anyone experienced this and how were you able to get help?

I have an iPhone 14 Plus that was originally on USC. Never had a problem with our T-Mobile 5G home internet system, but ever since the buyout/switchover happened, if I’m connected to the internet it will just randomly quit loading every few minutes. If I disconnect from the internet it will work off data fine, but I no longer have strong signal in places where it used to be great, which doesn’t make sense because it’s the same towers, right? Anyone else seeing similar problems?

Is this what we can expect? Also customer service was terrible, sounded like a sweatshop behind them. Had to repeatedly ask to 'say it again' because it was so noisy.

I have had many issues with Us Cellular to the point where my wife and I transferred to ATT under my parents family plan in April. ATT agree to pay off my wife’s phone ($600ish). In order to do that they sent a ATT rewards card in the mail to pay it off (took months to arrive though). Ive been getting emails and letters in the mail to pay the final bill for US Cellular. I’ve just been waiting for the ATT rewards card to pay it off. Today I called US Cellular to pay off the bill but all numbers I’ve tried they automatically transferred me over to TMobile. T-Mobile cannot find my account because it was already cancelled with US Cellular. I went into a US Cellular (district store) store and at first they also said they cannot look up my account because it was cancelled, after doing some more digging they found my account or like the history of it but on their end it says nothing is due/the balance is 0. The manager at the store thinks I should mail in a check to the Palatine IL 60055, address. I called ATT rewards and they said I should be able to pay the bill in person and there was nothing else they can do about it. I called ATT a few times and one agent told me the US cellular store should be able to “Postdate Payment” the transaction but the manager at the us cellular store said they cannot.

I also recalled US Cellular and it keeps transferring me to TMobile. After a while an T-Mobile agent gave me this number to call US Cellular 8889007678, i called the number but the us cellular agent just ended up transferring me over to T-Mobile saying that all accounts have been transferred over, before the transfer I tried to plead with them that my account was cancelled so it never transferred over. But she just kept saying “you’ll be able to resolve you bill with them” she transferred me and the automated robot asked for my number and I plugged it in and it said that there is no account with that phone number (of course!!) this was very frustrating.

Should I just wait it out? Mail a personal check? Let the bill go to collection?

It just never sends me the 6 digit code to my phone, but the first one to my email is no problem. Any solutions of tips? Thank God I already paid my bill for July.

Just picked up my phone to a pop-up asking me to switch to T-Mobile. The pop-up can't be dismissed. The text:

>Switch to T-Mobile?

>Your phone will restart to complete T-Mobile setup. During setup, T-Mobile apps and features will be installed. Some apps from your previous service provider that are no longer needed will be removed, but your personal data and files will remain safe.

And then only two selectable options, Emergency call and Restart and switch.

This seems pretty legitimate but I just wanted to know if anyone else has gotten the same thing.

from what i understood is that previous customers were grandfathered in on the same plan. i went from 50gb of hotspot data to 5gb of hotspot data. i now also have a data cap when before i have the unlimited even better 3.0 which doesnt have a data cap. if anyone else has had this issue how did they resolve it? going in or calling?

Was curious if any of your stores have shut down? I wish you all the luck in the world! I worked for us cellular for 20+ years and it saddens me what has happened

I am sharing this experience to reflect on a challenging period in my career. I was hired in October of last year at a US Cellular retail location. At the time of my hiring, we were informed that US Cellular had been acquired by T-Mobile. While initially concerned about the transition, I quickly adapted, consistently met and exceeded performance targets, and completed the T-Mobile training program. I became the primary resource for T-Mobile-related questions and processes within the store.

During this period, I successfully managed 20–30 US Cellular renewals and 5–10 T-Mobile activations per month. My contributions were recognized, and I was promoted to Store Manager. I took pride in supporting my team and driving results during what was presented as a significant opportunity for growth.

However, in April, during a conference call that I conducted on speakerphone due to lacking headphones, I learned—along with several customers present in the store—that our location was scheduled to close. Following the call, management instructed the team not to disclose the upcoming closure to customers. We were directed to continue processing upgrades and activations to maximize sales, with the explicit warning that sharing information about the closure could result in termination and loss of severance. We were also informed that we would be blacklisted from applying to T-Mobile positions.

The following two to three months were exceptionally difficult. The store faced chronic inventory shortages, with no devices available for upgrades. Customers experienced extended wait times—often 45–50 minutes—for direct fulfillment orders, new SIM activations, and account changes. System access was further restricted two days before the final closure, preventing in-store SIM swaps and forcing us to route requests through customer service, which involved lengthy hold times. In an effort to manage the high volume of frustrated customers, I began providing self-activation guidance where appropriate.

Later, we learned that T-Mobile had only acquired a portion of the towers, with the remainder auctioned or sold to AT&T and Verizon. This raised questions about the overall strategy and its impact on both employees and the customer base we had worked hard to transition.

As corporate store closures were announced, the environment became increasingly stressful, with heightened customer frustration due to limited resources and service challenges. I submitted my resignation with a one-month notice but ultimately shortened it due to escalating tensions. While I acknowledge moments of raised voice on my part during particularly difficult interactions, these occurred in response to highly confrontational situations, including one instance where a customer continued to demand a new device despite repeated explanations of our zero inventory status.

This experience, while difficult, has provided valuable lessons in resilience, team leadership under pressure, and the realities of large-scale corporate transitions. I am now moving forward in my career with a clearer understanding of the importance of transparent communication and employee support during periods of change.

Thank you for allowing me to share my perspective.

Sorry for the rant, but wanted to get the honest truth off my back since it all doesn't matter anymore. Signed a store manager in a small town.

On a Pixel 7.

With US Cellular I very rarely had issues with signal strength. Pretty much always at full bars of 5G with the occasional dip to two or three, but pretty rare.

Ever since the whole merger thing started It's been a crap shoot on getting 5G in general much less full bars.

I've spent the last several months now having more time on LTE than 5G. And when I do get 5G it's rarely more than one or two bars.

Anyone else running into this and any way to fix it other than maybe moving to a different carrier?

100% my fault for not reading the new plan I signed for, but just found out that my hotspot from the phone is rare limited to 600kpbs while the unlimited on my cell phone is at 5g speeds. My plan with US Cellular dropped me to 4g when I went over the data limit, hotspot and phone included.

I am just flabbergasted by the notion that my cell phone gets 5G speeds, but when I connect a device to my cell phone to use the internet that is streaming through my cell phone, I am rate limited to 600 kilobits per second.

I am not the most tech savvy person, but I don't understand how my carrier is able to limit the modem inside my phone from providing the same speeds that it is downloading from the towers. Nor do I fully understand the distinction from a consumer's point of view other than the willful desire from greedy overlords at tmobile trying to suck every last nickel from me by putting a paywall in front of 'features'.

Very disappointed, cancelled and have just switched to google Fi. I was with Us Cellular since the early 2000s. It was great while it lasted.

Anyone else having this problem? My wife has an 11 pro. You’ll pry it out of her cold dead hands. It worked great. Right until our coverage switched over. Now it’s a dog, often refusing to send texts when she clearly lte connectivity. When it does finally figure something out texts come and go in jumbled order.

Disclaimer

This is not an official T-Mobile, UScellular, or Walmart document.

I'm writing this based on my experience working in Walmart Wireless (Electronics), my previous experience working for Sprint before it became part of T-Mobile, conversations with customers, and what I've personally observed during the UScellular account migration.

This guide is intended to help answer some of the most common questions I've been hearing. Policies, promotions, and account situations can vary, so if you're unsure about your specific account, contact T-Mobile Customer Care or visit a Corporate T-Mobile store.

1. Who This Guide Applies To

This guide is primarily intended for:

• UScellular Postpaid Individual accounts

It does not specifically cover:

• Prepaid accounts
• Postpaid Business accounts

T-Mobile has provided limited public information regarding migration timelines and account-specific scenarios, so much of this guide is based on real-world observations and customer experiences.

2. SIM Cards & Account Migration

Customers who had a valid mailing address on file with UScellular generally began receiving new UScellular/T-Mobile Hybrid SIM cards around mid-March 2026.

These Hybrid SIM cards can connect to both UScellular and T-Mobile networks during the migration period.

Customers already using eSIM generally did not receive a physical SIM card.

Once your account is eligible, migration to T-Mobile may occur automatically. Many customers reported seeing a black screen indicating their phone was switching carrier networks and asking them to restart their device. Others discovered their migration had completed when attempting to log into their UScellular account and were redirected to T-Mobile.

As of Monday on June 22, 2026, based on what I've personally observed, the majority of consumer accounts appear to have already migrated.

3. Getting a SIM Card

One of the most common questions I receive is where to get a replacement SIM card.

Many customers assume Walmart or other retailers can provide free T-Mobile SIM cards. Unfortunately, that's generally not the case.

Retail locations typically sell T-Mobile SIM cards at the standard retail price (commonly around $35).

If you need a replacement SIM card, here are your best options:

Option 1

• Log into your UScellular account.
• Verify your mailing address.
• Request a replacement Hybrid SIM (if eligible). $0.00
• Complete the migration once your account becomes eligible.

Option 2

• Create or sign into your T-Mobile account.
• Verify your address.
• Request a SIM card if your migrated account allows it. $0.00

Option 3
Visit a Corporate T-Mobile Store.

Many third-party T-Mobile dealers have limited inventory and often reserve SIM cards for new activations. A Corporate T-Mobile store is generally the best option for migration-related assistance.

4. Port-Ins & Port-Outs

This is probably the biggest issue I've been seeing.

Since the UScellular network became part of T-Mobile, attempting to port your UScellular number into T-Mobile as a "new customer" can create unexpected issues depending on your account status.

I've seen situations where:

• A brand new T-Mobile account is created.
• New temporary phone numbers are assigned.
• The number transfer never completes because the customer is no longer considered to be coming from another carrier.
• Promotional offers become ineligible.
• Customers are left with activation fees, possible restocking fees, multiple accounts, or delays while customer care attempts to resolve everything.

If your UScellular account is already in the migration process, I strongly recommend confirming your eligibility before opening a brand-new T-Mobile account solely to qualify for a promotion.

5. Legacy UScellular Plans

After migration, your account may still show one of the previous UScellular plan names.

These are generally considered legacy plans and are no longer available to new customers.

UScellular offered 3 generations of unlimited plans between approximately 2017 and 2026, including:

• Unlimited Basic 1.0 / 2.0 / 3.0 - Not Eligible For Promotions
• Everyday 1.0 / 2.0 / 3.0 - Eligible for 36 Month Promotions
• Even Better 1.0 / 2.0 / 3.0 Eligible for 30 Month Promotions

The plan structures, premium data allowances, hotspot limits, pricing, and upgrade eligibility changed several times throughout those years.

If your migrated account still shows one of these plans, that is normal.

6. Promotional Credits & Plan Changes

This is another area where customers can accidentally cost themselves money.

When viewing plan options on T-Mobile, the website typically estimates only the difference in the monthly plan cost.

It may not account for promotional device credits you currently receive.

For example: ( Based on 3 Lines )

You may save $20/month by switching to Essentials.

However, if switching causes you to lose three promotional credits worth $11.33 each, you've actually lost $33.99/month in credits.

In that situation, your "cheaper" plan would actually cost about $14 more every month.

You keep your Promotion Credits, when you Upgrade to T-Mobile Experiance more, or Experiance Beyond plans. But you lose those Credits if you downgrade to T-Mobile Essentials.

Before changing plans, always verify whether your current promotional credits will continue.

7. Experience More & Experience Beyond

If you decide to move from your legacy UScellular plan to one of T-Mobile's current plans, here are some of the differences you may notice (features may change over time):

Experience More

• Continue receiving eligible UScellular promotional credits (if applicable)
• Higher premium data limits
• Larger premium hotspot allowance
• 24-month upgrade eligibility (where applicable)
• Netflix with Ads included
• 4K streaming support (where available)
• Expanded international benefits
• Travel and hotel discounts
• Complimentary AAA membership offer
• Voicemail-to-text features

Experience Beyond
Includes many of the above features plus additional premium benefits such as Hulu and annual upgrade eligibility for qualifying devices.

Always compare the total monthly cost after promotional credits, not just the advertised plan price.

8. Billing Credits (Device Promotions & First Bill Confusion)

One of the most common sources of billing confusion during device upgrades is how promotional credits apply to your bill.

In most cases:

• Promotional device credits typically do not appear immediately on the same bill cycle as the upgrade/purchase
• Instead, they usually begin applying within 1–2 billing cycles, depending on activation timing and billing cutoffs
• This often causes the first bill after upgrade to look higher than expected

Why this happens

When you upgrade a device:

• You may be billed the full device installment amount upfront
• The promotional credit has not yet started posting
• AutoPay may only cover the “normal expected bill,” not the temporary higher amount
• Any shortfall can result in a remaining balance or, in some cases, late fees if not adjusted manually

Important tip for customers

If you are upgrading a device, it’s generally safest to:

• Expect the first 1–2 bills to be higher than normal
• Avoid assuming the promotion is already active
• Manually review your bill after the next cycle closes to confirm credits have started posting

Credit timing clarification

In most billing systems:

• Credits apply based on activation and billing cycle alignment, not simply the purchase date
• If a device is activated near the end of a billing cycle, the first credit may appear on the following statement
• Once the credit begins, it typically continues monthly for the full promotion term (e.g., 24 or 36 months)

Key takeaway

Your total promotional value is still correct over time — but the timing of credits can make the first 1–2 bills look “wrong” if you’re not expecting it.

Small correction to your original idea (important)

This part you wrote:

>

That’s not generally how carrier billing works. Credits don’t alternate monthly — what does happen is:

• Partial billing cycles (proration issues)
• Delayed first credit posting
• Misaligned billing cycle cutoff timing

So I removed that idea and replaced it with a more accurate explanation.

8. Iphone Activation Troubleshooting.

Iphone 8,X,XR,XS ,11 Use 4G LTE
Iphone 12 & newer , Have 5G
Iphone 14 & newer, are E-Sim only ( no physical sim card )

Doesn't Matter if your doing Activation via Sim Card or E-Sim
Make sure the software is up to date Before attempting to activate.
Wifi Is Required to update.
Download the IOS update > Install the Update > In Phone restarts.
( This is the biggest mistake ) Many think they are up to date, but they are not !!!
Check for updates again > Because phone may have done a Large update, up to a certain point.
Then still has to do another small update.

(I'm Explaining this , like i would explain it to my non techy parents )
Iphones have to be up to date to Authenticate through the apple services as well as the carrier to activate. If the Iphone is not up to date, it will attempt to authenticate, and fail, and will still attempt to activate with the Carrier, the Activation data gets corrupted.

Which Results in these possible outcomes.
* No Voicemail box
* No 4G/LTE/5G
* Calls , but no text/internet
* No calls, but gets text/internet
* calls, and internet, can text, but Can't do Group Texts.
* SOS only mode.

To Fix this issue, You normally have 2 options.

1. Finish updating the phone, Call Customer tech support, and wait 3-7 Days for the back-room to Rebrand/Fix the data corruption via ticket.
2. Finish updating the phone, Backup all your data to the apple Cloud or computer.
3. Factory Reset the phone , and then start the activation process again, it will clear out the data corruption with the carriers network automatically.

Final Thoughts

Hopefully this guide helps answer some of the common questions surrounding the UScellular to T-Mobile migration.

My goal isn't to replace official support, but to help customers and fellow employees avoid some of the confusion, unexpected billing surprises, and account issues I've been seeing during the transition.

If you've already migrated and your experience was different, feel free to share it below. Every account is a little different, and additional real-world experiences can help others going through the same process.

If you have questions, I'll do my best to answer them based on my experience. If I don't know the answer, I'll gladly say so.
