Hello!
When I started to use my sim Card M Tarif was activated and I was using that one. Then I cancelled it and started to use S Tarif but now I want to Change it again but I’m not able to do it from the Website. I did the earlier Change on the Website but this one it tells me to contact the costumer Service. How can I solve this Problem because at the Moment I don’t have any Tarife. Should I go to any O2 shop to solve it?
I appreciate your help.

welcome here in our community. 
I have activated o2 My Prepaid M for you and reimbursed the costs incurred during the time you did not activate a package yourself.

I couldn’t change anything myself so I visited one of the stores. Then I cancelled my prepaid Card and switched to a contract. Bceuase with a contract I’ll have more Internet with same amount of Money.
Have a nice day!
