Cancel Prepaid Accout + Number Transfer


    Hey guys,


    my t-mobile prepaid sim-card ended today and I'm going to switch to another service which is related to the office I'm working now.

    - Do I have to cancel my prepaid contract or is it going to end automatically after some time if I don't pay the fee? (after what time?)

    - I don't find an account number, my bill only says ******731, I can't find anything else. My new service needs an number to be able to transfer.


    Thank you very much!
