Hello @Yudai I think that there may be an issue with your account. I’m sure a T-Mobile moderator will be able to assist you resolving this issue. I expect they will get back to you after the weekend.

Hold on help is coming ;-) 

Hi @Yudai, welcome on our Community! Thanks voor mentioning this, I'll be happy to help you! You have to manually delete your old Pre-Paid subsciption in the app, because it's nog longer active. You can then add your current subscription to your My T-Mobile account by clicking on the button '’abonnement toevoegen'’ or in English '’add subscription'’. When you click on it, you will be asked for your phone number and an SMS with a verification code. If you enter this in your My T-Mobile account, your new subscription will me added and you can view all your data. 

Can you let me know if it worked? I'd like to hear it from you! 

Kind regards, 

Pharwin

Dear all,

Thank you for your help!

It worked somehow, but there are many issues on the system apparently.

Hopefully it will be improved soon!
