Works ok, but simple improvements could make it better

I do like the convenience of only carrying one phone. The call quality is good and the texting feature works well.

Why not a higher score? The first thing that I’m certain annoys everyone: stop asking me about my call experience every time I make a call. I don’t need the extra notification constantly. Occasionally is fine, but every call is so tedious.

I would like to be able to review texts or see the number that called while I’m on the line. You can’t navigate through the app while on a call.

I haven’t been able to open the app in several weeks. The app starts to open and then goes black. Thankfully I can still make calls from my cellphone app.

Very stressed

Jenn Neubeck has hacked into my T-Mobile account for over two years and nothing has been done. Fraud has been working on it since September and haven't heard anything from them. She has opened digits in my name using me and my sons phones listens to our conversations and tracks me. Stole money opened accounts in my name and spread my name and personal information all over the dark web. I've been a customer of 23 years and never been treated so bad and had my privacy and identity taken away

No Survey!

There is a really annoying banner that appears after every single phone call asking for feedback about call quality. I HAVE ZERO DESIRE TO TAKE A FREAKIN SURVEY AFTER EVERY PHONE CALL. GET RID OF IT!
