Unable to purchase phone online

I have the same problem!! And I do not want to pay the $20 fee when I should be able to do it myself

So is this ever going to be fixed? I have the same problem. Tried on Firefox, Chrome, Edge and mobile app. Very frustrating.

June 12 and still happening. Tried to upgrade both phones on our account and crapped out in the store purchase process after Select Phone > Add to Cart > Choose Number > Select Accessories screen on PC and Mac.

My existing phones are paid off, so in theory, I should be a flight risk you want to rope back into another 24-month contract, but you're not making this easy sale easy.

Here's the screen I get after choosing "Skip accessories:"

This is happening to me as well--chrome, edge, phone, chromebook, whatever.  Hard to give away my money this way.  If i had wanted to go to the store, i would have done that. The convenience of online ordering just went sideways.

Having the same issue, have talked to a representative on the phone twice and even did a two hour long Chat with a support tech on the website. Still unable to get the system or website to give me my upgrade. This is beyond outrageous and it looks like this has been going on for well over a year without a fix. This is complete crap. Looks like they also stopped monitoring these Support threads.

@tmo_elesa​ @tmo_mike_c​ So you are saying you have had this "technical" issue since Nov 2018 and its still not resolved.  You should just tell your customers that it is not possible to upgrade/order phones over the internet and that they need to goto the store so you can charge them the $20 upgrade fee and see if you can convince them to purchase another more expensive devise or expensive plan, I get you run a business but dont waste your customers time spending hours trying to see if its a browser issue when this is probably just a way to get people to the store.  If that's NOT the case then you have serious issues with your development staff who cant fix a customer facing problem for over 8 MONTHS.

@magenta644033 try calling in to order it, worked with me and went smoothly, explain to them that this is a known issue and they shouldnt charge you the $20 upgrade fee.

Thank you! I called and was able to place the order over the phone (they

also waived the fee). The representative was also very helpful in

explaining exactly how the promo works and was very knowledgeable. A

significantly better experience compared to the website/app or in store.

If you're looking at this in 2019, hopefully this helps you! I found out the issue was my card. For some reason, the system wouldn't let my Discover credit card complete the order. When I swapped over to a Visa the order went though fine. Sucks because I wasted a Messaging Expert's time but hopefully this explains the mystery for some people. Try a different card maybe?

I think I have found a solution to this issue.  After dealing with this for 6.5 hours with a retail store, online messaging, telephone CSR's and finally the TMobile Twitter Support team, I tried using an old ZIP CODE while checking out..... and it worked.  I moved over a year ago... I used my current address, but changed the ZIP CODE in the billing portion to my old zip, and it worked.  I have had the same issue with Chevron gas as well..... my address is current in all of my banking institutions and bills.  This was an enormous hassle and waste of time - this needs to be corrected immediately - there is no reason so many people should be having these issues due to a faulty payment services system.
