Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
Are you able to receive phone calls? Have you tried another SIM-card in your Xperia Z1 to see if you experience the same behaviour?
others also cant call me..
I'll check an other sim card later..
Okay, keep us updated! 
now i checked another sim card from another provider.. and it works..
It does not sound related to a problem with your phone if it works with another SIM-card. I would suggest that you contact your network provider to see if you can order a new SIM-card and hopefully it will work fine.
