[UPDATE] The good news is that T-Mobile has reached out to us and clarified the situation; there's nothing to worry about. This was just a glitch and did not impact a lot of users. Here is a full statement:
There was no cyberattack or breach at T-Mobile. This was a temporary system glitch related to a planned overnight technology update involving limited account information for fewer than 100 customers, which was quickly resolved.
[ORIGINAL STORY] T-Mobile is one of the biggest phone carriers in the U.S. and has some compelling offerings for those who are on the network. The speeds and coverage are excellent, too. So, there is no doubt that most users would want to use this carrier. However, it appears that the service has gone through another breach, and this time, it appears to be within the app where users have started seeing other users' personal information.
Disabling your credit card is the right way until T-Mobile handles this data breach
Highlighted by two sources, it appears that the Bill and More tabs in the official T-Mobile app on both Android and iOS are showing third-party information to some of its customers. This information looks like it belongs to other customers, and the scary part is that it includes their current credit balance, purchase history, and the last four digits of their credit card, along with expiration dates, phone numbers, and addresses. It is safe to say that this is not something to take lightly and could potentially cause a lot more harm.
We'll get to the bottom of what information you're seeing through your app and ensure everything is correct. Please send a DM so we can sort this out and ensure your information continues to stay protected. ^CharlesOpacki https://t.co/8DIvLVByJj

This is not the first time T-Mobile has experienced a data breach. Earlier this year, the carrier faced a breach that ended up impacting 37 million accounts. Then, there was another breach back in April, and now we are looking at this rather scary breach.
Sadly, at the time of writing, we don't really know what can be done to prevent any harm. If you have your credit card added, we suggest disabling it until the situation is resolved. T-Mobile formerly made an announcement telling the customers that things are under control. We hope that no significant damages are done because this sort of leak could end up financially harming many consumers.
