Hello @g.b., welcome to our community! I totally understand that you want your new sim card working, let's look at a solution together! Is your old sim card still working? Then I can help you with this. I have to do an extra verification by SMS. If you can share the code with me, I can help you with the activation of your new sim card.
When did you request the new sim card? When I get the number, I see that it is a Prepaid connection. Can that be correct? I only see that the address information does not match what is known under the number in our system. Can you provide the correct zip code + house number in your profile?
I'd love to hear from you!
