Hi @TR Ribes, thanks for creating a topic for this issue, I can definitely get your account to work! It seems that your current account is still connected to your old cable Internet subscription. Do you want to create a separate account for your new subscription or do you want to replace the old subscription with the new one in your My T-Mobile account?

• To create a new account, please register it via: Account registreren.
• To replace the old subscription, please send me a private message with your new email address.

Either way this will be solved for you!
