TL;DR: Most carriers bill monthly service in advance. After you cancel or use a vacation suspend, the next one or two statements are usually just true-ups (credits/fees) for time you already paid. Don’t rush to pay a “final” bill—check the service period dates and the credits first.

My 26-year Verizon hotspot: the backstory

This line has been around for almost 26 years—an unlimited 4G broadband hotspot I pushed hard (some months 1+ TB). It started at $50/mo, crept up, and I carried $7/mo insurance. When I decided I didn’t need it, I put it on Vacation Suspend and tried a transfer of billing responsibility (ToBR). r/verizon removed my post and banned me under their rules, so I moved on: stayed suspended, then canceled.

See receipt (Reddit post was removed)

Suspend → credit → final bill (what happened)

1. Vacation Suspend: Verizon confirmed a $10/mo cap during suspension.
2. Next bill dropped: September fell by about $53.33 vs. August due to re-pricing.
3. Cancel later: The “final bill estimate” showed a –$6.75 credit (negative balance).

Why you still get bills after canceling

Carriers bill service in advance for the printed service period. After you suspend or cancel, the system reconciles what you prepaid vs. what you actually used—so you might see a full bill, then a credit, and finally a small refund (negative balance) or taxes/fees adjustments.

Read your invoice like a pro

1. Find the Service Period near the plan charge—this is the month you prepaid.
2. Match your Suspend/Cancel date to that period. If it falls inside, expect a credit.
3. Scan for Credits/Adjustments (suspend re-pricing, partial period, tax/fee corrections).
4. Separate Device balances if you financed hardware—those still come due at cancel.

Heads up: Some carriers say they don’t prorate the final month. That’s separate from billing in advance. You can still see credits tied to suspend re-pricing or prepaid time. Always check the printed service period and the credits math.

Bottom line

Most people pay a month in advance. When they cancel, they often don’t owe what that first “final” bill shows—the later statements usually reconcile into credits or a small refund.

You think wireless carriers have your back? Think again. With AI getting smarter and scammers bolder, 2025 is shaping up to be a nightmare for anyone with a phone. I’m Curtis Matthews, the Mobile Wiseguy, and I’ve seen it all – from SIM swaps stealing your identity to fake AI voices tricking you into handing over cash. Carriers like AT&T, Verizon, and T-Mobile talk big about security, but the truth? They’re playing catch-up while you pay the price.

This post breaks down the hottest scams hitting the wireless world right now. No fluff, just the raw facts from real cases and industry reports. Let’s dive in.

1. SIM Swapping: The Identity Theft Kingpin

Scammers convince your carrier to transfer your number to their SIM card. Boom – they own your texts, calls, and two-factor codes. In 2025, this is exploding thanks to weak carrier verification. Hackers use social engineering to impersonate you, grabbing bank accounts or crypto wallets in minutes.

• How it happens: Fake IDs, leaked data from breaches, or bribing store reps.
• Real horror: Victims lose thousands before noticing. One report shows SIM swaps up 30% this year.
• Carrier fails: T-Mobile and Verizon have been hit hard, with slow responses leaving customers hanging.

Protect yourself: Set a PIN or passphrase with your carrier for port-outs. Avoid SMS-based 2FA – switch to app authenticators.

2. AI-Powered Imposter Scams: The Voice You Trust is Fake

AI is the new weapon. Scammers clone voices from social media clips to call pretending to be family or your carrier. “Hey, it’s support – verify your account.” Next thing, they’re draining your wallet. Prompt injection attacks let them hijack chatbots too.

• The hustle: Texts or calls start it, leading to phishing links or fake refunds.
• 2025 spike: FTC says imposter scams via phone dropped, but AI versions are surging via texts.
• Carrier role: Verizon’s AI customer service is frustrating users, making real help harder to spot from fakes.

Tip: Hang up and call back using the official number. Never click links from unsolicited messages.

3. Refund and “Free” Plan Scams: The Bait and Switch

Carriers pitch “free” lines or refunds, but it’s a trap. Xfinity Mobile got called out for lying about a year-free deal – customers end up billed anyway. Similar to those iPhone “free” promos we exposed last week.

• The scam: Fake reps offer overpayments or upgrades, then steal your info.
• Business hit: Porting delays hide the fraud until it’s too late.
• Senior targets: Scams tailored for older folks, like fake tech support calls.

Fight back: Check bills monthly. Use carrier apps for changes, not phone reps.

4. Smishing and Text Traps: The Everyday Killer

“Urgent: Your account is suspended. Click to fix.” These texts lead to malware or data theft. In 2025, they’re more sophisticated, mimicking real carrier alerts.

• Why it works: Urgency + fake links = quick clicks.
• Carrier blind spots: T-Mobile ranks #1, but even they warn about switching risks.

Pro move: Block unknown numbers. Report to FCC or your carrier.

Why Carriers Aren’t Stopping This

Big Three (AT&T, Verizon, T-Mobile) invest in AI for their own service, but fraud prevention? Spotty at best. Subscriber fraud – signing up with stolen info – is rampant, and they’re slow to flag it. Meanwhile, MVNOs like RedPocket drag their feet on fixes, taking days for simple issues.

Street-Smart Tips to Lock It Down

• Use strong, unique passwords and enable account locks.
• Monitor for unauthorized changes via email alerts.
• For businesses: Get a consultant like me to handle ports and upgrades safely.
• Report scams: FTC.gov or your state’s AG.

Walk into any store right now and you’ll hear the same pitch: “The iPhone 17 Pro is on us.” Sounds like a steal. But let’s cut through the marketing noise — it’s not free.

You’ll still cough up taxes on the full retail price (~$1,100). In Florida that’s about $77, due right away. None of that shows up in the flashy ads.

Then there’s the upgrade fee. AT&T charges $35 for installment upgrades and $50 for 2-year contracts. Sure, they waive activation fees on new lines — but upgrades? They get you every time.

And the big hook? Bill credits. Month after month. For 24, 30, even 36 months. You leave early? Boom — you’re stuck with the full balance. That’s how they keep you locked into high-cost unlimited plans.

Here’s the hustle:

• AT&T: Trade in an iPhone 13+, they drip out $1,100 in credits over time.
• Verizon: “Free” phone only if you add a new line and stay on their priciest plans.
• T-Mobile: Same deal — trade-in, big plan, long lock-in.

Truth: Free phone deals aren’t free. They’re a trap to keep you paying more every month, with taxes and fees hidden in the fine print.

In my ongoing battle with AT&T over an unwanted and fraudulent $376 tablet charge, I finally got some resolution — but only after a grueling, hours-long chat with support and supervisors. This post is a continuation of my original story about the unexpected tablet charge and billing issues, which you can read here.

The Situation

After disputing the unauthorized tablet charge, enduring multiple phone calls, and returning the device, I was promised credits by several AT&T representatives and supervisors. Unfortunately, many of these promises were not honored, leading to frustration and confusion on my end.

Using Chat Transcripts as Proof

Florida’s two-party consent rules mean phone calls aren’t easy to record. Chats, on the other hand, give you a written record of every promise, every number, and every “we’ll get back to you.” That paper trail is the only reason these credits finally landed.

For more on why I rely on chat logs (and how AI chat can help or hurt), see my Verizon AI post: Verizon’s AI Customer Service: Frustration for Many, Smooth for Me

Key Resolutions From the Chat

• AT&T ultimately credited a cancellation fee of $325 and additional taxes and fees totaling over $51.
• Pro-rated charges disputed during the chat were agreed to be removed.
• The autopay discount was discussed and arranged for re-enrollment to get the discount going forward.
• My bill was reduced dramatically from $704.66 to $244 after all credits were applied.

Social Proof: My X Post About the Bill Credit

Rant: Wild how carriers won’t let you record calls without permission, but you can print chat logs. Just spent 2+ HOURS fixing an @ATT billing mistake—got my bill down from $704 to $244 with a credit. Like I’ve said before… THEY should be paying us for the wasted time!

Final Thoughts

This experience highlights the challenges business customers face when dealing with billing mistakes and slamming practices. Even with documented proof, it took a long fight just to get AT&T to acknowledge and credit their error.

For anyone facing similar issues, do not give up. Keep thorough records, ask for supervisors early, and leverage chat transcripts if phone call recording isn’t allowed.

The post AT&T Billing Battle Continues: Chat Transcript Reveals the Long Fight to Get a $376 Tablet Charge Credited appeared first on Gangster Mobile | Real Talk on Wireless Plans & Carriers.

Slamming is when someone adds services to your wireless account without your permission. This is exactly what happened to me — and it turned into a multi-day ordeal that chewed up over two hours on the phone, multiple transfers, a trip to UPS, and a fight to get my own money back.

How It Started

I have six lines on my AT&T business wireless account under MobileWiseGuy. I only personally use a tablet — the other five lines are for family members. I wanted to block long distance on those phones. That request alone took four hours and three different representatives who ultimately could not block the long distance.

When the next bill arrived, I saw about $180 in long distance charges. One of my family members — the main user of one of the lines and an authorized contact — called AT&T. In the middle of the call, she three-wayed me in because the AT&T rep was pushing her to get a tablet before removing the charges.

I asked directly, “Are you saying the only way you’ll remove these charges is if we get a tablet?” The rep mumbled. I asked again, on a recorded line. The rep mumbled again. The third time, the rep finally said, “No, you do not need a tablet.” I made it crystal clear — I did not want a tablet — I only wanted the long distance charges removed.

Returned… or So I Thought

The rep said they’d cancel the tablet order and remove the charges. The next day, a tablet showed up at my door. I shipped it back immediately and received an email from AT&T confirming they had received the device and credited the $0.99 tablet cost.

Canceling the Line

When I called AT&T to cancel the line, the rep asked if I wanted it canceled at the end of the billing cycle. I said absolutely not — why would I pay for a month of service for something I never asked for? If you cancel something, always make it clear you want it canceled immediately or they will charge you for an extra month.

The Bill Shock

Despite the return and the cancellation, my next bill included a $376.51 charge for canceling the tablet and the monthly service. When I called to dispute it, the first two reps asked me to provide tracking for the return — even though AT&T’s own system showed the tablet was received and credited. That’s when I demanded a supervisor.

The Payment Arrangement

After spending two hours on the phone, running to the UPS store to confirm the return, and another half hour canceling the line, I finally got a payment arrangement in writing. AT&T said they could not apply the credit immediately, so they set it up so that after I paid my regular $206 bill, my service would not be interrupted. The $376.51 credit would appear on my next bill.

Lessons Learned

• Always confirm “cancel immediately” — not at end of billing cycle.
• Returning a device does not cancel the line — you must call in and cancel service.
• Keep every email and screenshot confirming returns and credits.
• Slamming — adding a service without your permission — can happen at any carrier.
• Consider pausing or removing AutoPay during an active billing dispute.

Extra Tip

When returning a device, you still have to call and cancel the number tied to it. Keep all tracking information and expect an email from AT&T confirming they received the device and credited the account. Business customers have 30 days to cancel service and return a device — do not wait until the last minute or you’ll be scrambling.

Another real-world business porting nightmare — this time involving Goodcall Housecalls, who attempted to move a wireless number from AT&T Wireless to AT&T Office@Hand (powered by RingCentral). Despite being an in-house transfer, the process turned into a multi-month saga of rejected PINs, contradictory instructions, and endless delays. What should have been a simple port became yet another example of how telecom bureaucracy can bring a business to its knees.

Customer’s Original Email

(Number redacted to xxx-xxx-4230)

Good afternoon, Curtis and Robert,

I am writing this email to express my extreme frustration with the process of switching from AT&T wireless to Office@Hand. I have never experienced anything like what I have been going through with this transition process. To say it has been seamless, as implied in our initial discussions, is an extreme understatement. If we did not need to port the number regardless, I would have chosen another company. I need to know what is going to be done from this point forward to get this number ported over!

“We were told our two active account emails were ‘inactive’ and had to create a new one — then wait 30 days to request the PIN.”

I sent an email 2 days ago in response to a PIN, I updated the PIN once I received it and am still being told it is incorrect. I need someone to take responsibility and drive this home.

At the very least, I am asking that we remove any remaining fees owed on the xxx-xxx-4230 number, credit last month’s payment as this should not have taken another 30 days to try and port, as well as remove the onboarding fee of $150 for Office@Hand. I have taught myself and set up the system for use as is with assigned numbers.

Key Failures in the Process

1. Unclear PIN requirements – We were never told there was a separate transfer PIN that had to be requested. We wasted a month trying various known account PINs, with four failed attempts, before learning the real requirement.
2. Broken automated systems – The *PORT (*7678) shortcut does not work (confirmed by Curtis). Account access loops prevented us from generating the PIN online.
3. Email restrictions – AT&T claimed our two active account emails were “inactive” and required creating a new one, then waiting 30 days to request the PIN. This forced us to keep paying for unused service.
4. Multiple department runaround – After finally reaching the risk management department, we were told to pay off the account balance before receiving a PIN — a new requirement not mentioned earlier.
5. Misleading confirmations – After being told an email was sent with the PIN, nothing arrived. Another rep later admitted no emails were sent the previous week.
6. PIN rejection even after confirmation – Once the correct PIN was entered into Office@Hand, the port request was still rejected as “incorrect” two days later. No follow-up response was provided.

“We have been trying to get this going for over a month and have exhausted our resources to port this line.”

Please respond with what actions AT&T will take to remedy this situation and help us get this number ported ASAP.

Regards,
Tanisha Nowak
Chief Technology Officer
Goodcall Housecalls

Timeline of the Porting Attempt

• May 2025: Initial attempts to port the number begin. Customer (Tanisha Nowak) and COO (Cassandra D’Addio) try all known AT&T account PINs without success. AT&T assistance is requested to troubleshoot. The number is temporarily forwarded to Office@Hand, but the goal is to display the main number — still pending.
• June 16–23, 2025: First formal PIN requests fail. Customers told to call *PORT (*7678) — non-functional — or use broken account portal loops.
• June 26–July 3: Same PIN (993310) resubmitted multiple times, repeatedly rejected. AT&T cites “incorrect PIN” despite confirmations from both sides.
• July 7–14: Office@Hand claims they’re “waiting on losing carrier” — which is also AT&T. Multiple escalations yield no progress.
• July 31: Credit request for $232.04 (onboarding fee + two months MRC) submitted; RDS ticket opened. Port still incomplete.
• Early August: Customer still chasing updates — now more than two months after the process began.

Analysis & Commentary

This case shows that even when porting within the same brand — AT&T Wireless to AT&T Office@Hand — the process can be just as slow, error-prone, and inconsistent as moving between competing carriers.

The key problems here were:

• Lack of clear, up-front requirements for transfer PINs.
• System errors and dead-end automation.
• Contradictory instructions across departments.
• Failure to follow through on promised actions.

“We should not be waiting another week!”

For a small business, this meant months of disruption, extra costs, and wasted time — all for something that should have been routine.

Takeaways for Businesses

• Confirm porting requirements before beginning the process.
• Document every interaction — names, departments, and case numbers matter.
• Request fee waivers and credits when delays are the provider’s fault.
• Don’t assume same-company transfers will be easier than switching providers.
• If you’re an AT&T business customer, learn how to get your AT&T Business Transfer PIN before starting a port to save time and avoid rejection.

Good Morning,

I am writing in response to your email stating that this case has been resolved and closed. Respectfully, this matter has not been handled appropriately, and your summary leaves out key issues that caused significant hardship.

After nearly 60 days and over 20 hours on the phone with Comcast/Xfinity representatives, I—not your team—finally discovered the root cause. The account number Comcast was referencing was a 10-year-old, closed account that was still showing on your side. I uncovered this only after downloading the Xfinity app and noticing the discrepancy. It is extremely concerning that Comcast/Xfinity was unable to identify this error during the entire process.

In the meantime, Barbra continued to be billed by Comcast while she had no access to her phone number and voicemail, despite multiple requests for assistance. No one from Comcast or Xfinity provided the support she needed during this period. The lack of accountability and responsiveness has caused unnecessary frustration and business disruption.

While the number has since been ported to AT&T, the way this was handled is unacceptable. We expect acknowledgment of Comcast/Xfinity’s failure to identify and resolve the account issue in a timely manner, as well as clarification on how Comcast will ensure Barbra is not billed for services she could not use.

Please do not consider this case closed. We expect a detailed response addressing the above points and an appropriate resolution for the time and money wasted due to Comcast’s mishandling of this matter.

Sincerely,
Curtis Matthews
(on behalf of Barbra Zigann)
    

Good morning Barbara and Curtis,

Thank you for contacting our executive office with your questions and concerns. We value your business and would like to thank you for the opportunity to resolve this matter for you. Unfortunately, our attempts to contact you have been unsuccessful. However, we were able to resolve your concern. Please retain this email for your records. 

Our back office team, working to port the phone number xxx-xxx-7866 to the Xfinity Mobile residential account, was unable to complete the process because the phone number in question was sent to AT&T. Notes about the port show August 16, 2025, at 6:18 AM EST. There are no further actions that can be taken at this time, as the phone number no longer shows with Xfinity. Please refer to AT&T for any additional questions about the phone number and its availability.

Your case is closed due to having discussed the above information. Please reach out to our care team with any additional inquiries or concerns.

Sincerely,
Kandi H.
Xfinity Mobile Executive Resolutions
    

Barbra called to get the MDU line today and they told her they will call back. I was not on that call but why when trying to set an appointment for a MDU line would someone say they will call back?
They also said someone went out 8/11/2025 but for what?

Good Day Curtis Matthews / Barbara Zigann,

This email is being sent to you in the absence of your assigned Fix Agent... it appears that the issues you have outlined involve two separate accounts. Before we respond, we will need account verification:

• First and last name on the account in question
• Service address in question, including City, State, ZIP
• Last 4 digits of stored payment method
• Or, the complete account number

Kind regards,
Faith H. for Sam G.
Xfinity – Executive Customer Relations
    

Xfinity (Kandi H.):
“It is understandable to be frustrated... At this time, there are no additional concrete steps I can provide, as I am still working with the technical team...”

Curtis Matthews:
“We are in exactly the same position as we were on June 23. Repeated apologies do not help. Assign a knowledgeable technician who can correct the mismatch and ensure this port is completed immediately. Confirm next steps and a resolution timeline today.”
    

Curtis:
“I remember the third error… We were told the port was confirmed and the number was released back in April 2025. Barbra had no idea what that was about — she only started this on June 23.”

Xfinity (Kandi H.):
“I will see what could have been referenced for April… So far I have not seen anything referencing changes in April 2025.”

Also on Aug 10: Kandi apologizes for missing calls due to Fri/Sat off-days; provides callback info.
    

Aug 9 — Curtis to Xfinity:
“Please have someone call Barbra ASAP and fix this immediately.”

Aug 7 — Barbra to Xfinity Support:
“I have been working with Curtis Matthews on saving my business phone xxx-xxx-7866 for now over two months… even with an expert like Curtis we had a difficult time with Comcast and Xfinity. This has been a nightmare. There is not enough compensation you can provide to help me now. I sincerely hope others never have to go through this.”
