O2 Prepaid Monthly to Annual

Hi @Dorady ,
thanks for sharing your request regarding switching the tarif plan. 💙

The Jahreskarten offer is a special offer which can ordered directly at o2-freikarte.de
If you allready have this option, you are able to extend the duration for a further year. 

Switching from another tarif plan to the Jahreskarten offer is not possible, sorry. 

best regards
Michael

If I order it, what will happen to my current number? I want to retain it
