Hello @Kokkanis nice to meet you here in our community. 
Can you describe your order please? What, when and where have you placed your order? 

kindly regards
Michael

I placed an order for an eSIM 3 weeks ago.  O2 send me mail saying I can activate my sim.  But until today the letter with the sim did not come.  Ihre Auftragsnummer lautet: XXXXXXXX

Hello @Kokkanis ,

maybe there is just some kind of misunderstanding here, if you ordered a change to an eSIM, then you won’t get a physical SIM send to you. What exactly have you ordered, an eSIM or a classical simcard?

Kind regards, Sven

Can I find my barcode for eSIM somewhere in o2.de??

Hello @Kokkanis ,
thank you for your answer. Which tarifplan are you using and how have you ordered the eSim Card? 
Have you only tried it once? Dit you received a notice of confirmation of your order placement? 

kindly regards? 
Michael

@Kokkanis i hope that everything is fine for you. 
If there is anything we can do for you, keep us informed. 

kindly regards
Michael
