Hello I have a few questions regarding the Prepaid Max 999gb Plan. I have just bought the sim for this plan at the O2 Store and registered an account in the Mein O2 app, My questions are:

• I linked my German Bank Account and gave permission for Direct Debit (Sepa Mandate) in the App. Will I be automatically charged monthly (automatic top up of the prepaid credit) once my plan expires (after 28 days), thus the plan will be automatically reset and restarts anew?
• If not, is there an option for me to automatically do this ?
