Hello @Raye Chang, if you didn'’t get the activation code, you can request a new one. If you use this link: https://mijn-bestelling.kpn.com/activatie/resend_actcode/

Hello , when i put my sim number and my post code , it says that it finds nothing with this number.

i just receive the post-courrier with id verification , i didn’t receive any e mail to activate my sim , what should i do 

Normally if you receive the simcard by post courier, the sim is already activated. You can start using the simcard on the date you agreed with us. 

Thats what i did , put the sim in my phone , but nothing works

Then there is someting strange going on @Elias40dam, can you fill in your profile? After you've done that, i can look what is going on with your subscription.
