Ok, I don’t normally give poor feedback, but I’m hoping my feedback makes this app better. The concept is brilliant and necessary for people like me that want the comfort of a business line and a personal line on the same phone. With that said, the app just doesn’t do basic things. I am not an app developer by any stretch, but you gotta go back to basics. Get general. A line within a phone is being done by many different companies, but come on, it’s T-mobile, you guys have figured out some pretty basic needs of the consumer across the company, I would really love to see it applied here. KISS, keep it simple SERIOUSLY! Something as simple as clicking on a text and having it show as read is not happening. Sent a text last night and nobody got it. Had to uninstall and reinstall the app to get it to actually work. I click on the line and I get a weird message that says client is setting it up. I don’t even know what that means. These are basic things that I can in other apps (not separate phone line apps, but other apps in general that have a chat feature). I am anxiously looking forward to when I can come back and update my review and my rating.

Needs real investment

This is a critical app and a major reason I chose and stay with T-mobile. I understand from one of the T-Mobile Engineers that there is finally a thought to invest real resources in making this a great app which is really promising. I am glad to hear that because I was worried they would abandon it which would cause myself and many others to leave T-Mobile.

Having said all that the iOS app continues to be plagued with problems especially on the text messaging side. For a time I could not input the phone numbers to send a text message ... the app would just crash. Responding to texts worked fine. That problem was apparently fixed with an update.
Everything seemed to be working ok, but after some recent update I can no longer send text messages to any international numbers just returns a “failed” result. Domestic works fine and I can receive all texts, and I can receive all texts from anywhere ... but not reply internationally!

This seems specific to the iOS app as it works fine from my desktop Digits app.
I suspect this issue will get fixed ... but have no idea when the next app update will roll out.
Frustrating. Hopefully T-Mobile will get this Digits App which I view as a vital offering, sorted. Hope to update the review then. This should be a 5star app.

Problems after problems, can I give it a negative star??

I’ve had Digits since December of 2017. Since day 1, it’s been one problem after another. You’d think that after 1+ years, they’d improve the app and the purpose of its use. I use this for work and 3/4 of the time, it stalls, freezes, suddenly quits, “line not active” pops up, or when I log out and back in, it shows all my read messages as unread so I end up having 90+ unread messages that I now have to go back and “read”. The voicemail feature is also whack; can’t delete voicemails after reviewing... some days it work and some days it doesn’t. I’ve even had ALL of my texts deleted and vanished therefore having to start all over. I’ve called at least 1-2 times a week since having Digits and it’s always been the same “oh, we are so sorry for your frustration with this, we are working hard to improve the app”. So many problems, that I’ve eventually stopped calling it in. Of course, now I can’t delete it because all of my staff have my # and I don’t want to get a new #/phone. Digits is useless. If you don’t have it yet, please save yourself some sanity and DO NOT DOWNLOAD DIGITS.
