“Terrible app and service — App and service is terrible. Have to use the app to set up or switch phone and internet over. But the service is so slow the app won’t load and customer service refuses to just manually enter your information to get phone/internet service set up. It would have taken me 5 minutes to switch over and verify my address, however the app is so slow and customer service is so bad it took multiple…” — ★☆☆☆☆ · English“Worst Cell Service — Take away the Wi-Fi and you can’t scroll nothing you can’t watch more than two seconds of a video before it stops and buffers like it’s 2008. Take away the WiFi and the network can’t operate sluggish, buffering, video call drops if even connected. Why should I pay for internet if I have to use my home internet. Maps , buffering stop back to map quest sheets. Network resets , hours on the phone…” — ★☆☆☆☆ · English“TLife — I was not able to view the fuel rewards button. Its not responsive. The app frozen.

“Kids Sync App doesn’t work — With all of the app updates I can no longer find all of my kids watch features and it no longer accurately tracks and customer service is lacking in person they send you online and they say just reset it lol” — ★★☆☆☆ · English“After recent update — Google Maps in sync up devices do not work so gps tracking is useless” — ★☆☆☆☆ · English“Avoid this App, Avoid T-Mobile — This app is the worst thing I have ever been FORCED to use, and it's the reason we are leaving T-Mobile. It's literally that terrible. They force you to use it, and I can rarely find my daughters Sync-up watch. They force you to talk to support on here, and the AI they make you use is the worst. Bring Jon Legere back, the new leadership is running the company into the ground. PS - Any…” — ★☆☆☆☆ · English

“App forgets login information — The app always forgets my login information (esp. Face ID) along with my router admin password. Doing anything requires re-installing the app.” — ★☆☆☆☆ · English“Useless and Frustrating — The most wasteful, time consuming app ever made. You cannot do anything important on it and it logs you out every time you stop using it. Their biometric Face ID used for login is terrible and has NEVER (not one time) worked for me despite successfully setting it up 3 separate times.” — ★☆☆☆☆ · English“Always states my credentials are incorrect — Have to consistently log in and provide PIN, only to be told my credentials are incorrect. My primary account holder has suddenly changed various times without me changing.” — ★★☆☆☆ · English

“Impossible to resolve issues — Hyperlinks in support pages dont work. Chat function doesnt work. Hard to connect with a live person. That person hardly speaks english when you do connect. They cant explain your problems or dont have the authority to fix them. Promotions are a wash and lock you in, all while rate increase inexplicably.” — ★☆☆☆☆ · English“App chat refresh — Application is crashing frequently when we are chatting with the agent” — ★☆☆☆☆ · English“Unbelievably Worthless App — I wish I could upload a video of trying to use this app. When trying to chat with tech support, the app completely glitches, infinite spinner, and can’t even type into the chat interface. The keyboard incessantly closes while typing, can’t even type a full word before the keyboard vanishes” — ★☆☆☆☆ · English

“Benefits didn’t show up — After updating the app, my T-Mobile Tuesdays benefits completely disappeared. My husband’s phone still shows several offers he can claim, but I don’t have any. I used to receive weekly benefits, so this is very frustrating.” — ★☆☆☆☆ · English“More and more flaky with each update. — Nothing makes you feel all warm and fuzzy inside like T-Life telling you “You’re not eligible for these benefits!” even after years of being a T-Mobile Home Internet customer. Yes, if you log in all over again every time you open the app, you can eventually get to T-Life Tuesday Benefits, but the moment you close the app and open it again, it treats you like the red-haired…” — ★★☆☆☆ · English“App Issues — I really like the app and receiving free items and also playing the games to try and win prizes. But I really dislike the fact that the app logs you out and when trying to log back in it gives you a hard time to get back in the only time I can actually use my app is every Tuesday. I almost feel like it’s false advertisement, I almost had my last week of choosing coupons to redeem so that I didn’t can…” — ★★☆☆☆ · English
