T-Mobile Fiber: Gigaspire Negative Reviews
The app isn’t functionalYou shouldn’t have own two apps to do basic things like pay your bills or to check you devices or just manage them. If I can post picture I would. “Your app is unable to connect at this time. Please verify that your app is updated to the latest version. contact your service provider if you need further assistance.” Is all this app ever says. I used to have spectrum I switched to T-Mobile fiber in August 2025 it honestly feels like it was worst decision we have ever made because we nothing good to say and we highly don’t recommend t mobile fiber. The agents doesn’t know how to work the darn apps or T-Mobile fiber internet they send you to somewhere else they give you a runaround the technicians don’t know what’s the problem with the Internet or how to fix these apps. But obviously this has been a known issues/problem. You can’t use the app, you have to use a different app to pay your bills and it feels like a chore..Catsmom20Version: 25.2.2
My experience with TFiberThis is the worst experience I have ever had with T-Mobile Wi-Fi and Internet. My router keeps saying that it’s connected. The light is green, but it will not connect to any of my devices in my home and I called T-Mobile customer service and they keep connecting me to technical support where they don’t answer the phone and they have you on the phone for at least an hour because they know that it is an outage. They keep gaslighting the customers when clearly it’s a problem with their Internet my Internet has not been working for the past 24 hours. I have been going through this since I purchased the Internet in October 2025. I am glad to say that this will be my last month. I will be going to spectrum I’m tired of getting gaslighted and the runaround about this Wi-Fi. I do not recommend..KaosBaddieVersion: 25.2.2
Disappointing AppI just signed up for T-Mobile Fiber. It’s far too soon for me to comment on the actual T-Mobile fiber internet, however, trying to perform the most basic updates to their Fiber app is an exercise in patience. You need to be ready to look at their spinning circle over and over again as it tries to revalidate everything constantly. What’s really frustrating is when it regularly tells you that it cannot update because it’s offline after just adding a new device. Never mind that everything else is working fine on the network. The layout and process flow of the app is fine. It’s solely a performance problem, but when you have 50+ devices on a new network to set up, it gets old real quick..RipwagVersion: 25.2.0
Really Disappointing AppConstant spinning circle - updating a device name or assigning it to a room/person is an exercise in patience and takes MULTIPLE attempts to save. Disappointing functionality as well - no way to limit a person/room to a certain amount of internet time per day. I don’t care if my kids can ACCESS the internet between 9am-8pm but I’d like to LIMIT that access to 2 hours per day. No way to do that and the option was available in the Cox app. Also no security/parental controls in the app (aside from changing your WiFi password), no billing options in the app, and no way to assign a device to the network closest to it - only a static map..LaSme13Version: 25.2.2
Absolutely terrible support and serviceI was an early adopter of fiber in our area. 3 months now and it has been nothing but problems. Constant loss of signal at the modem outbound, constant app issues. I have now had to re-create my app account 5 times as it will randomly state no account found. Register again with sane info, and the app will work a few more weeks, although it is pretty much useless. I’m’ve found you can do 99% more by logging directly into the modem instead if using this app..BeachbumtechVersion: 25.2.2
Janky appApp has been unable to connect for at least a day. Keeps telling me to make sure I have the latest version of the app. I do. Wish the app would just tell you theirs an outage or something instead of gaslighting me about what the problem actually is. Also don’t like having to call someone every time there’s an issue with the app or internet. Why is there no option for a chat? I’m almost ready to switch companies just so I don’t have to deal with this app..PokéyowomonVersion: 25.2.2
Poor appCan’t speak to a person. The app won’t reboot device. Service has been disconnected and can’t get in contact with anyone to resolve the issue. T mobile said it was an outage but the site said issue was resolved but I still have no service. Can’t even post this without giving a star which I’m now trying to disconnect my whole and return to spectrum but can’t even do that cause I can’t connect to anything or a person cause it keep saying it’s after hours..Lamesha22Version: 25.2.2
Useless appHad T-Mobile Fiber installed and the tech had me download the app. He tried numerous time to connect to the network and failed. He told me to try over the next few days and if it didn’t work call customer support. When I called, the agent sent me down a rabbit hole and caused the router to disconnect. Finally a competent helped me get internet back online but the app still will not connect..NYCMLCVersion: 25.2.0
App cannot see replaced routerThe first day something happened to disconnect us, the next day they replaced the router. Internet works now, but the app doesn’t do anything. We went through the “replacement“ settings several times, it gave an error, saying make sure the app was up to date. Yesterday when the app worked, it was really slow as it spun and spun..Marc.cardwellVersion: 25.2.0
Useless app before they even install your serviceOrdered T-Mobile Fiber 2 weeks ago.
No installation date, no update, nothing.
Decided to check the installation status but T-Mobile website blocks paste on the login field, so no browser on iPhone works with password managers.
Downloaded the app specifically because of that — and the app says my account doesn't exist.
So to summarize: no internet, no install date, forced to download an app just to log in, and the app doesn't even work.
The only reason I'm stuck with T-Mobile is they're the only fiber provider at my address. If there were any alternative, I'd have canceled already..KDLaoVersion: 25.2.2
Service Not worth itAs everyone else has mentioned, we switched to T-Mobile about 4 months ago and the service is consistently being interrupted saying that the app is unable to connect and to make sure the app is updated. I honestly should have read the reviews before switching, big mistake on my part..Disappointed at the lowestVersion: 25.2.2
ProblemsEveryday I get a notice about “new device” on my network but they’re not new, same equipment. Also the time limits are difficult to set up and are a hour off (10pm is really 9pm etc) app crashes a lot and takes a long time to load. Often says I don’t have an account and make me sign up again and again..PorkchoppaulVersion: 25.2.2
Extremely frustratingVery difficult app to use. Continually tells you that it cannot connect and to make sure app is updated. That makes modifying internet access for your devices impossible. Close the app, reload, wait 30 seconds, pop-up error, rage, repeat, good luck….X27001Version: 25.2.0
Can’t use app to pay billYou can’t use app to bay your bill and unless you have phone service with them it’s impossible to login to their website and pay your bill.Spurrier1Version: 25.2.2
App does not workT-Mobile Fiber is great but the app is not operational and should not be deployed for general use. The set up is seemingly straightforward however inevitably results in an error message and states to make sure you have the latest version. Love T-mobile Fiber, strongly dislike this application..JaSites90Version: 25.2.2
New customerI can’t speak for the internet itself but I just got this app downloaded and trying to modify the devices has been a pain. I can’t imagine why T-Mobile would have so many apps for items that are together..Maribravo2Version: 25.2.2
Waste of time and energyVery bad experience with this app. Got the T-Mobile fiber about 5 days back and this app never work. Even with the technician this wouldn’t work and he set up my ssid by calling someone. The customer care don’t know about this app..SS-atlVersion: 25.2.2
Absolute trashConstantly says it can’t connect and when it does, most of my devices don’t show up. Devices that have been on my network keep showing up as new devices. The Lumos app worked fine. This one is trash..OG mageVersion: 25.2.2
No option to turn router feature offWhile you can control some features the settings are very limited in scope compared to a Orbi NETGEAR and similar devices.VaweatherVersion: 25.2.2

T-Mobile Fiber is TrashI’ve had constant problems, this WiFi is useless…. It was cheap for a reason, they have a long way to go to provide decent WiFi. I’ll be going back to Xfinity….Poz MajorVersion: 25.2.2
Waste of dataThis doesn’t work properly and neither does the fiber optic cables. It’s horrible and when they send someone to fix it they don’t know the problem either..TheyaskedmetoratethisVersion: 25.2.2
Horrible appThe app tells me I don’t have an account but I can sign in via the web page. I was using it just fine for two weeks but now it’s crapped out on me. It was great up until now..BshiddkekdVersion: 25.2.0
Love T-mobile Fiber. Hate this app.T-Mobile Fiber is amazing. This app, not so much. It is horrendously slow. It times out. A lot.
Has the potential to be good but that requires investing in app devs that know what they’re doing. This is a reskin of the Calix app so yeah. It’s just bad..ValienVersion: 25.2.0
TerribleApp never works. Always get a popup telling you to either update the app or contact customer service. Neither of which solve the issue..Ec149Version: 25.2.2
App randomly lost my account and made the re setup a nightmareThe app randomly said my account couldn’t be found even though my T-Mobile Fiber service was already installed and working. It then told me to make a new account and re-add my router, but required a QR code or manual device details that most people probably don’t keep after installation.
I had to dig up the original router box from last year just to find the MAC address, serial number, and QR code. The app also didn’t show my exact router model, so I had to guess the closest one. That is not user-friendly at all.
For an internet service app, this should be much smoother. If the router is already tied to my service, the app should be able to recover it automatically through my T-Mobile account instead of acting like I’m setting everything up from scratch again. Very frustrating experience..Von plays YtVersion: 25.2.2

Bad serviceWe’ve had T-Mobile for years. Got Lumos fiber. Had at least 6 techs come out. It’s always dropping. Every tech complains about the last tech so it seems they all suck. About to cancel this service since I work from home..Rm robotVersion: 25.2.2
The app never worksI have had T-Mobile fiber for about 6 months now and it sucks. That app NEVER works and the service is always out. I have been without internet for 2 days now. I am currently looking up a different provider in my area..IamCremeVersion: 25.2.2
Poor serviceAfter being on T-Fiber for 3 months I have to say it sucks. Open the account & all my info is there but one thing: an ability to pay on this app or on the T-Life app. I had to call 3 months in a row to pay. They couldn’t find my account though it’s all on the T-Fiber app. I lost my service because the live support can’t find my account. I gave them all of my info. Now I’m out of service & will be going to another service provider. It’s not having the money to pay but not being able to pay. T-Mobile charges a lot but the quality sucks. Bye.Kalip1971Version: 25.2.2

Dumps settings randomlyTwo months after configuring the router and mesh satellites this app lost all configuration settings and login info. I had to sign up a second time and now it can’t find one of my satellites. Customer service for T-Fiber sucks so if you’re not network savvy I would avoid this. It’s not reliable..JljesseVersion: 25.2.2
