Unable to make payment

This is still not working..  Please either fix this now or undo whatever genius untested changes were made that screwed it up, test it on your own time and make sure it works before you re-deploy those changes.

Gracias

For those still having this problem, I may have found a temporary work around.

Use the T-Mobile app on your phone to access your account, and make a payment from there. I tried this on a whim earlier and it worked.

Not a great solution, but until the website is fixed this may save you some trouble.

For the third month in a row this is still a problem. I'm on the newest release of Chrome on Mac OS High Sierra.

I have a valid credit card on file but it doesn't show up in the list and I cannot add a new card.

I'm able to use Safari as a work around.

There are errors and deprecation notices that show up in the JavaScript console within Chrome, likely meaning the software being used is out of date. This should not be a 3 month fix. At the very least create a patch or work around until you can update the entire system.

Chrome is the most popular browser. Letting this persist for so long makes me question how much you value your customers since it creates a frustrating user experience.

I understand that your development team is probably really busy but this is important and likely impacts a lot more people than are posting on here.

Unbelievable isn't it? doesn't give one much confidence in T-moble, this should not be happening. I had to use their messaging system to alert people that this was even happening. THey finally got my account straightened out but I wonder where my personal data was for a few week.

T-Mobile... this is unprofessional. spend some money and get some quality software people onboard.  You customers should not have their personal data messed with, your customers should not be you beta testers.

Yes this is the way I've been paying for the last three months but not my preferred method. Thanks for the tip to help others

EXACT same problem today for me as well!  Tried on different browsers, the phone, app, etc. with no luck.  Hopefully we get a response!

I'm having the same problem: all my saved payment info is gone, and when I try entering routing/account numbers or card numbers, I get a "Enter a valid [card/account/etc] number" message. I tried paying via the app on my iPhone (which has worked every month over the last two years), and paying online (Safari 11.01) without success.
I was finally able to make a payment when I used Chrome (63.0.3239.84), but it's annoying that I can't do it from my phone like always.

Having this same problem thats only started since T mobile has upgraded their website. have never had a problem in the past. I know the card is valid because i JUST used it at the ATM. I know the number is being entered right and attempted to several times. but still im being told to enter a valid card number. I have tried on both the website and mobile app and having same problem so clearly its not the browser its t mobile having the problem. I only have one card if T mobile wants me to pay my bill they should fix their system

I've now started having the same problem. The stored card that I've been using for years isn't there, and attempting to enter new card information fails with "enter a valid card number" in red. (I've tried multiple cards, and I've verified several times that I typed in the number correctly.) I'm experiencing this bug with desktop Chrome, and with the browser on my phone.

T-Mobile: do you have an estimate for when the bug in your web site will be fixed?

Yep, same problem here.

Doesn't work on:

Chrome (fully updated)

Firefox (fully updated)

Brave browswer (fully updated)

Mobile app (fully updated)

Just get the "enter valid bank information" in red. It's definitely valid!
