Hi,
Today I received the internet modem from KPN - Is there any possibility to activate internet faster (the activation date is 19th February). The modem and the Wi-Fi is visible to my devices but it doesn’t work. Also I haven’t got my “klantnumber” so i cannot use acount on KPN webpage.
Hi 
Unfortunately it isn't possible to activate the services earlier than communicated. Thankfully it's only two days away so hopefully you'll be able to manage without internet at home until then.
Your customer number should be on the contract you received. It should start with either a 9 or a 6.
If it's not on there, try checking in your MijnKPN. You can follow your KPN orderstatus on your MijnKPN account too, so hopefully there's more information for you there. 
If you have any further questions, don't hesitate to ask!
