I understand the need for MB's directly. I'm just like you when it comes to using data . Whenever you try to activate a bundle is your previous 100% used? It should be 100% used otherwise you can't activate another. Also do you use My T-Mobile app or the website when ordering more MB's? When you face issues with the app I would suggest to use the website. Usually that works right away. I see you activated another GB bundle. So have data again.
If you face any troubles in the future, please let us know!
