Unable to make payment

STOP pretending it is sth on customer end, I have the same issue since June, clearly you guys want to make our lives miserable, I considering switching to the AT&T PRepaid service

Wow, 4 years later and they still have the same issue. Worst service ever... EVER! 

For the last 3 months I’ve  needed to refill I’ve had this problem. Trying 2 different computer 3 different browser and different card, the form highlights as red right away saying the card number is not valid. 

I'm still having issues making payments via cc or checking account online, keeps saying "Enter Valid details", this has been happening for the last several months when they went with new online format. It's frustrating for this is the way I pay my bills, ONLINE.  When are they going to get this bug fixed...customers shouldn't have to keep waiting or deal with these issues when trying to make payments. Keep it simple.  No one seems to understand when I call to get assistance.

It's the programming department...FIX this BUG!!!!

I also cannot pay my bill.  I have been trying for 3 days now.  Online I see "Enter a valid card number".  On the phone it says it can't process the payment with the card number I provided.  I am using the same card I've used every single time for the past how many years.  I have tried Chrome, Edge and Internet Explorer.  I have tried using the T-Mobile app on my iPhone, and it gives me the same error.  If T-Mobile wants their money, they need to fix this.

Their difficulty with input formatting extends beyond cc numbers...they can't get it right with phone numbers either.  Phone numbers, think about that. Anyway, about a year ago I couldn't logon using the same saved account info I always used, which was my phone number with parens and dashes in the number.  Strip those out, logging in using the same old password worked just fine.

Not exactly high on the list of troubleshooting steps these days.  In fact, I'll bet the last time I had web form input validation or formatting problems with a credit card or phone number I was probably using Netscape over dial up.

Now I can't pay a bill because the pay by cc goes to the list of saved payment methods, but none can be selected. I can delete or add all the cards I want, just can't use any of them.  Maybe a server has a bad floppy drive, who knows.

I knew this thread is old but the for some reason I’m having the same issue last month. I paid my bill and it said please contact T-Mobile but they still took the money off my bank and I tried to pay my bill this month and it says please enter a different card, but they still took the money off and nobody doesn’t know where the money went to. This is crazy. 

Hi, 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.

I have solved my problem and hope to help everyone.
Let me talk about my situation first: I changed my number a month ago. I have used the previous number for nearly three years without any problems. The problem was the first recharge after I changed my number. t mobile Card number is invalid. Please try again.
mmmmmmmm......I entered the account with the previous number and deleted all registered credit cards. Then enter the new (current) number to add recharge, no problem at all! ! ! !
When you want to change to a new number, the clerk should remind you to log in to your account to delete all credit cards. After all, you don’t use this account anymore, do you?

same.

For the last 3 months I’ve  needed to refill I’ve had this problem. Trying 2 different computer 3 different browser and different card, the form highlights as red right away saying the card number is not valid. 

Just ran into an issue today that sounds exactly the same, I entered 3 different valid card numbers, both Visa and Discover, into 3 different browsers, and was not able to successfully validate a card. Also the T-Mobile App seems to be down. This is for a prepaid plan.

I ended up having to go through the 611 payment over phone service, which worked well enough. Hopefully this is a temporary re-emergence of this issue and I can set up auto-pay later.

Same. 

Same issue. Can’t refill my account. It’s been suspended !!! I’m out of the US now and can’t even add the app on my phone - it shows wrong region . What to do??

Hmm that's a little odd. I did some checking on this and didn't find anything going on with the payment system. Are you able to try making the payment using the automated system or the MyAccount app?

I'm currently having the same issue, trying to pay my bill but I keep receiving an error "Enter a valid card number." I tried two different cards and I still get the same error.

Hey @mad_cow  and sorry it's giving you a rough time but let's get you some help. What browser are you using? Have you tired another browser? Is it just happening on the website or have you also tested the T-Mobile app to see if you can make a payment? Please let us know so we can help. Thanks!

I have the same problem - for some reason the system does not show the credit card you guys have on file and forced me to add a new card - I enter a valid credit card number - and the validation states its not a valid credit card number

Using Firefox 54.4.1 (64bit)

I tried Safari - and there the existing credit card is shown, and payment went through without a problem

I am also unable to make a payment. However only on Chrome, Edge worked. Chrome not only does not allow any credit card number it will not show the ones you have saved either. This is on multiple computers. Please fix the issue.

Same here.. did not work with google chrome, but worked on edge.

I had trouble refill my phone from Denmark I could not get in to my account ,I got to the part where show the image ,but there were none.

and then try again after 24 hours ,the same happened every day, I am now past my dead.line and lost my money,

my soninlaw has away that make the browser think you are in USA , and it worked on my husbands account , but when we tried again for me

it failed .

Since it's not working on Chrome, have you checked to see if there are any updates for that browser? You could also try clearing the history for it and giving it another shot to see if that helps. If this is still an issue, please let me know. Thanks!

My issue somehow fixed itself two days later for no reason at all. I had tried Firefox and Chrome and both had not worked, but now they work. Weird.

That's great news that yours is working @mad_cow .

Has anyone checked out the payment option to see if it's working? Please keep us posted.

Same issue when making a payment "Enter a valid card number" keep displaying in red.  I've tried Firefox and Edge browsers and different credit cards.  But making a payments using my iPhone appears to be working.

It seems those new "green" TMobil cards are useless thru the TMobil system. I spent 50.00 to pay for another month of service at a Walgreen's store and tried to activate it thru phone, TMobil app, and even thru the chat with a representative and it couldn't go thru with them trying to activate it themselves The manager at the store where I bought it said it was processed the right way, and they don't refund money. The new TMobil green cards come with a 15 number pin and not with the usual 10 like before, so it seems to me that their system is not up to date and it's screwed. I talked to a representative for a second time and he told me that he was going to credit me 50.00 for the next month.I just came to check my TMobil account after midnight to see if I was credited for those 50.00 as their representative said and it hasn't been done, and my phone service expires in about 12 hours. It's unbelievable how a big corporation like TMobil can't tackle and solve a problem within their system.

I posted this for anyone who has the same issues and see that it's not an isolated incident!
