I was having the same issues and pissed of as everyone else complaining here but decided to try a few things before starting to cry.
I was having technical difficulties try again later error when I try to load money into the card after adding the packs. I realized that my Amex Bluebird card that I was trying to load money into was not a supported card and that was the reason for the error. Next thing, I went to a T-Mobile store and purchased a TMobile debit card which was advertised as a supported card. I gave it another try but no still getting the same error. Finally, I went to the TMobile website and registered my card. One more try and Bingo!! The card was loaded.
Folks, if you are getting the technical difficulties error. The reason is that you are either using an unsupported card type or your card is not activated. I thought my card was activated when I purchased and loaded my first $20 in TMobile store however the card is not actually activated until you go to the website and get it registered. So if you are trying to load money after purchasing the card in the store; first you need to go the providers website and activate your card then it should work.
Hope this was helpful.
