Hello @nick.ks.bae,

thank you for your enquiry with us

Actually, I don't know exactly what you mean by your question. Of course, you can use your prepaid card for longer than 1 year. As long as your card is still in use and you continue to top up the credit, it will remain active.
However, if you have not topped up your card after 6 months at the latest, it will be deactivated and can no longer be used.

Does that answer your question?
If not, then write us a little more detail about what exactly you mean

Kind regards
Jessica

Thanks for your detailed answer.

I’m thinking to buy 1 year prepaid sim for my kid.

Just wnated to know if my kid can keep using this longer than an year and I suppose it’s possible if I pay for coming year in advance.

Thanks again!!

Hi @nick.ks.bae,
thank you very much for your reply. Of course, the SIM card can be used for more than one year. For this purpose, it is only necessary to recharge the SIM card. How to do that, you can find in our english articles https://hilfe.o2online.de/english-o2-community-broadband-dsl-70/faq-section-and-overview-of-our-services-79700 .
Kind regards
