Telekom has changed cell phone settings?

I recently signed a new contract with Telekom and when I inserted the SIM card, the settings on my mobile phone were changed and some Telekom apps were downloaded. My question: How can I undo the settings on my Huawei P30. For example, my standard alarm tone has been changed and I can't find a setting to change it.

In any case, it would be great if someone could help me.
