  If you encounter an invalid MMI code on T-Mobile while buying or selling cryptocurrencies, the first step is to check your network connection. Make sure you have a stable internet connection and try again. If the issue persists, you can try restarting your device and attempting the transaction again. If the problem still persists, you may need to contact T-Mobile customer support for further assistance.

  When you come across an invalid MMI code on T-Mobile while buying or selling cryptocurrencies, don't panic! This issue can sometimes occur due to network connectivity problems. Firstly, make sure you have a good signal and try again. If that doesn't work, you can try clearing the cache of the app you're using for the transaction. If the problem still persists, reach out to T-Mobile support and they should be able to help you resolve the issue.
