Leben in Deutschland

Hello, God bless you and make you healthy! I have a question, these new laws that are being created in Germany, are they new for all immigrants or anyone who is new? If it's for everyone, I came to Germany almost a year ago, but I still don't have the documents, and I opened the anti-racism course a few days ago. Shiparks is with them and they have made some contracts, such as for sports, I bought a phone and SIM card, and I have to pay them every month, how will I pay it? It will take my bank account, I will open a new one, how? .. I am a little worried, I hope you give a detailed answer, thank you
