Hi everyone,

I currently have a prepaid eSIM and requested a replacement physical SIM. After about a week, the replacement SIM arrived at my address. However, I’m unable to activate it online through the O2 website. The system shows the following message:

SIM-Aktivierung nicht möglich

Der Vorgang kann aktuell nicht gestartet werden. Bitte versuche es in Kürze erneut. Sollte der Fehler weiterhin bestehen, kontaktiere bitte den Kundenservice.”

 

I called the English hotline for support, but they told me that they only handle contract plans. For prepaid SIMs, only the German hotline is available, unfortunately, I don’t speak German.

Has anyone experienced this issue before or know what I should do? Any advice would be really appreciated!

Thank you!

Hi ​@RubyNguyen 

welcome to our community. Pleasure to meet you here. 🙂

Did you follow the advice of Bumer and got in touch with our o2 Prepaid Chat?

If so, did you succeed? Or is there anything left to be asked?

Greetings and thanks to Bumer for assistance

​@o2_Manga I did contact them, but the support can not solve my issue unfortunately. They have to raise a ticket to the technician, it has been 3 days since then and still nothing happen :(
